PRESENT STATUS OF TECHNOLOGY

1.1 INTRODUCTION

The technology used is conventional type in unorganized sector. But the

organized sector players are using state of the Art Technology to manufacture the

bearings as per the global standards. The unorganized sector players are also

gradually switching over to technology up gradation.

The cluster units at Jaipur for bearing and Bearing component

manufacturing units are employing conventional technology, but with the cluster

level intervention the units have initiated technology. upgradation by employing

CNC Machine for turning, grinding, finishing, testing, etc.

The machining operation involved in manufacture of antifriction bearings

include forging of the rings, turning, heat-treatment, face and outer dia -grinding,

Bore and track grinding, finish and super finishing grinding , Demagnetizing,cleaning, inspection assembly and packaging, etc.

The Product

The Bearing is a machine element used in rotating parts of virtually every

machine. Bearing permit smooth low friction rotary or linear movement between

two surfaces. It employs either a sliding or a rolling action. If we could reduce

friction by only 10% in all the rolling bearing in use today, it would mean an energysaving equivalent to the combined out put of Not less than 25 large Nuclear Power

Stations. Bearing can be broadly classified into two segments:-

• Bimetal

• Antifriction – Bearings

Bimetal bearings (also known as engine bearings) are primarily used in engines

of automobiles or machines. The bearings are meant to reduce the friction

between the moving parts of the engine crankshaft or crank shaft or associated

support surfaces.

Antifriction Bearings include Ball Bearings and Roller Bearings. Roller bearings

can further be subdivided into tapered roller. Cylindrical roller, Needle roller, thrustbearings and other special application bearings. The main components of an

antifriction bearing are the inner race (ring), the other race (ring) the rolling

elements, cages (retainers) and seals. The following are the major types of

bearing.

a. Ball bearing

b. Cylindrical roller bearing

c. Taper roller bearing

d. Needle roller bearing

Further classification of these major categories is given below:

Single row deep groove ball bearings

Maximum capacity type ball bearings

Single row angular contact ball bearings

1.2 INDUSTRY OVERVIEW:

The bearing Industry in India can be divided into three segments; the

organized sector, comprising 12 leading manufacturers, located at Rajasthan,

Gujarat, Maharastra, Andhra Pradesh, Karnataka, Tamil Nadu, West Bengal and

Jharkhand primarily cater to the OEM Segment which are predominantly

automotive, Railway and other Industrial users. The unorganized sector includes

the small scale manufacturers and manufacturers of spurious bearings. The

unorganized sector contributes to about 18% of the total Industry turn over. The

unorganized sector players have a strong regional presence and mainly cater to

the needs of the replacement markets. The Indian bearing Industry is estimated at

Rs. 100 billion. The domestic Industry caters to the 74 % of total demand for

common varieties & sizes. The organized sector units contribute around 53% of

the Industry sales. The imports are about 26% of the total demand of the industry,


10/70

10

while about 18% import comes through official channels. There is also estimated

8% illegal imports. Legal imports generally represent the specialized / super

precision bearings not manufactured in India. Illegal imports generally represent

the entry of spurious imports of bearings. The legal imports are about Rs.1 8.00

billion while the spurious imports is about Rs. 8.00 billion.

The small scale units manufacturing bearing are mainly concentrated in

Rajasthan and Gujarat having 15 and 50 units respectively. The bearing

manufacturing units are also present in Delhi, Punjab, and Maharastra. The state

of Rajasthan has major concentration of about 100 bearing components

manufacturing units with 1000 to 1200 Vendors carrying out turning job work.

There are substantial No. of component manufacturing units in Gujarat,

Maharastra, West Bengal and Punjab also. The bearing component manufacturing

units are the vendors of organized sector, and unorganized sector bearing

manufacturing units for supply of inner & outer races, balls, rollers, cages, seals,

retainers & rivets. These components are also exported to Europe, United States

of America and other global customers.

There are about 450 to 500 number of spurious bearing assembling units situated in the

State of Punjab, Delhi and Gujarat, eating the market of organized & unorganized sector

players.

A number of global bearing manufacturers have established their units in

India through joint ventures or 100% ownership and more are expected to follow

1.7 Manufacturing Process

These are following three methods which are being used by units manufacturing

bearing races (Soft Turned).

BAR ROUTE :-

Bar route method is considered to be most economical method

manufacturing of soft turned Bearing Races. The following steps are involved in

this method. For the Inner Diameter upto 25mm , this method is more economical

as compared to the other method. That is why this method is more popular and it's

estimated that 70% of Bearing Races soft turning upto 25 mm I.D. size and 50%

Races of the total quantity of soft races manufactured by using this manufacturing

technology. Beyond 25mm I.D. this method is not much cost effective

Bar Turning

Ready for dispatch for further operation

This process technology is preferably being used for the outer Dia of 25mm or

higher size. Apart 40% of the total volume of Soft Races turning is being produced

by using above mentioned method in the cluster.


23/70

23

Forging Method:-

Bearing Races are manufactured by Hot Forging Method. The operation of Drilling,

parting, and trepanning are not required while using Forging Method. The Metallic

closed Dies are used in Hot Forging Method. This method is more suitable andeconomical for outer Dia of 30 mm and above size. In the cluster Approx. 10% of

Bearing Races are produced by using Forging Method. The Forged Bearing Races

are machined/finished as Indicated in the earlier method.

Further Operation for Bearing Manufacturing

The Bearing Outer & Inner Races manufactured by using any one of the

method mentioned above are then supplied to large scale and small scale Bearingmanufacturing Unit. The further sequence of operation for manufacturing of

Bearing are as under

Metal Shields - Bearing Metal Shields is protective closures which retains lubricants and assistin preventing contaminants from reaching internal surfaces.

Dust

Shields - The aperture usually found in the top cover housing is sealed to form a barrier toassist prevention of airborne contamination into the contact area

Shielded Bearings - A shielded bearing has a metallic shield on the backside andShielded bearings are not sealed bearings. With the shielded type of bearing, grease mayenter the bearing readily, but dirt is restricted by the close fitting shields. If there is noshield on the backside of this bearing, the excess grease can escape into the innerbearing cap of the equipment bearing housing.

Assembly : Assembly of various items, performing additional functions (greasing,marking, etc.) During each of these steps, the bearing manufacturing process layout iscarried out in compliance with total quality (self-inspection, SPC and TPM).

The following section present on Analysis of Business operation for the Bearing

and Bearing Component Cluster Jaipur. The following factors have been taken into

consideration in the Analysis.

• Raw Material

• Technology (Machinery & Production)

• Quality Standard

• Product & Marketing

• Entrepreneur & their Enterprises.

• Finance & working capital.

• Man Power Requirement

• Infrastructural Facilities.

• Business Development Service.

The raw material SAE 52100 Spherodised bearing steel only available from few Indian

Supplier.

• Indian Seamless Metal Tube, PUNE

• Indian Seamless Steel & Alloy, PUNE

• Mahindra Ugine Steel Company Khapoli.

Internationally, the accent is on achieving higher and higher quality levels of bearings.

Higher precision, minimum handling damages and maximum cleanliness are the thrustareas for development. Individual units have their own grading of quality. SKF, for

example, designates t, as Q77, Q66, Q55, where Q66 is reported as the prevalent level

and Q55 as the level aimed at International manufacturers are moving towards special

bearings, and sub assemblies involving bearings, where production of small batch

quantities becomes more attractive.

High rates and consistency of productivity have been achieved by the manufacturers

abroad by line manufacture. The market demands there, permit mass production

techniques and thereby bring in economies in production.

- As regards materials, closer grade and specification ratings are emphasised.

- Upgrading of technology has generally come not from within or from market forces

but usually from the collaborator's insistence, if the latter has stakes, either financial or

through its name.

The following testing facilities are not available in most of the cluster units.

• Chemical examination of steel.

• Non Destructive Testing of Material.

• Metallographic

The Machinery and equipment used by majority of SSI units for manufacturing of Bearing

Races are of sub standard and obsolete. Even the SSI Bearing manufacturing units are

using the second Hand Imported Grinding & Honing Machine which are having Lesser

Tolerance Accuracy so the bearing manufactured by these units are not preferred by

International Industrial Buyer.

The Product require high degree of precision the manufacturer are unable to

maintain Accuracy with in 2 microns. In accordance with the standard of International

Market. The existing plant & machinery can give accuracy with 4 microns.

The profile cutting operation of Bearing Races is not properly done due to Non

Availability of optical profile grinder.

Therefore lot of technological intervention need to be done in the area of

Machinery and Production in order to make final product as per International Standard.

The following observation need technological Intervention:-

(1). Use of Kerosene for Splash Cleaning for Assembled Bearing and Swab Cleaning

of Individual Parts.

(2). Inspection of Contamination level of the Bearing not inspected.

(3). Dust free Room/Assembly shop of Bearing not maintained.

(4) Erroneous measurement of parallelism, concentricity, flatness, taper, straightness,

radial and Axial clearance.

(5) Non Uniform Temp. in Shaker Hearth Furnace

(6) Mar Quenching Oil is being used for Quenching, but Mar Quenching Salt is not the

practice.


31/70

31

(7) Blackening Salt is full of Contamination.

(8) Sampling System is Erroneous.

(9) Roundness Testing is used for setting parameter of M/c.

(10) Micro Structure Like Type of Martensite, Retained Austenite, Benetic Structure , is

not being inspected.

(11) Sub-Zero Treatment is not being done in the cluster

(12) Micro Hardness measurement is not practice .

(13) Speed, Feed and Depth of cut for Turning and grinding are not optimum .

(14) Precision Measuring Instrument are all shop made.

(15) Fatigue Testing of Bearing not being carried out.

(16) No phosphating of Inner and outer ring .

(17) Go-No-Go gauges practice is not existed.

(18) Forging Dies are made of H 11 & H13 Hot Die Steel and Hot H21 & H 23 material.

The Quality of Bearing Races is concerned SSI Units have to follow the relevant

specification, drawing and other instruction provided by the purchaser. The system of

100% inspection is being followed without any process wastage. However some of the

Bearing manufacturer permit 1% process wastage. In the event of rejection the unit has

to make payment for loss of the raw material the Bearing Manufacturer.

The main defects of Ball Bearing Races are Track Centre out (for which Unit is 100

Micron) eccentricity in outer Dia and Track Dia or Base and Track Dia. The Radius form

on Outer Dia and base of race is not proper which Account for major rejection.

The gauge calibration facility are not available as the gauge are required to be calibratedperiodically in order to ensure the quality of product. The most of SSI/Artisan Unit of

Cluster do not have the well organized marketing channel and Demand forecasting

system and are facing marketing problem due to lack of availability of sufficient fund and

other resources required for Advertisement & Publicity, Credit required by the buyers,

Branding, Market Assessment etc.

Most of Artisan Units are having defective Product pricing system. The units are cutting

prices due to cut throat competition.


32/70

The Bearing Manufacturing SSI Units are only supplying to replacement market.

There is very vast scope to supply OEM & Other sector if they produce standard quality of

Bearing.

The Problem of duplicating and Reconditioning of old Bearing are another

Constraint in the Industry.

SSI Bearing Manufacturing Units are also facing challenge from Indian Large

Scale Bearing Manufacturer like SKF, NEI, TATA Bearing etc. as large scale unit have

made Huge Investment for Product Technologies, Collaboration from world leader of

Bearing Industry. Large Scale units have employed the professionally qualified work force

and producing at higher volume as compared to SSI Units, and hence taken a lead in all

the functional Area of Manufacturing, R & D, Marketing etc. More over these units areusing latest and Innovative technique to have their higher productivity, quality and

profitability. The SSI Units are far away and yet to adopt these technique tool for their

betterment 25 % of total demand for bearing industry is met by imports. While a part of

the imports come through official channels, there is also a huge volume of illegal imports.

legal Imports generally represent the specialized bearings not manufactured in India.

There are a large variants of imported bearings, each holding a small market share in

India. Though, the quality of bearings manufactured by large players in India is

comparable to world standards, domestic manufacture is not viable due to the small size

of the market segment.

It becomes uneconomical to manufacture such type of bearings as it includes huge

capital expenditure. Illegal imports generally represent the entry of spurious imports of

bearings. In the past, the Indian bearings industry was highly protected on account of

very high import duties ranging from 150% to 240% ad valorem. As a result, illegal

imports via smuggling and under invoicing of imports was the order of the day, accounting

for a high 45-50% of total imports. While duty rates have come down over the last few

years, a few countries like China, Russia, Eastern Europe dump their excess production

at a very low rate. This leads to a huge price differential between domestic and imported

bearings (almost 40-50%), encouraging imports.

• Most of the unit, the enterprise structure is proprietary or partnership type. The

proprietor/ partner himself look after the Management Aspect and Keep over all control of

the functioning of the unit and in most of the cases they do not posses the requiredtechnical/Managerial back ground.


33/70

33

• Technological Awareness of Entrepreneur are not upto the level. It need to be improved

so they can successfully compete the era of liberalization and globalization.

Finance is the most critical problem of the Industry in term of shortage of finance,

delayed payments, difficulties in getting bank finance and additional requirement of credit.

• Units require to maintain large inventory and it's the experience of manufacturer that the

working capital need are not fully realized by the bank & financial institution and it directly

affect their market.

• The SSI Units faces common problem regarding availability of skilled man power, A

worker After working for a period of few year in this Industry leave the Job to start his own

turning unit or to get higher wages from another unit.

• There is no regular training facilities available where the manufacturer and worker

undergo need based training.

• The SSI Units also faces problem about less availability of trained man power such as

turner, tool maker etc.

- The Tiny/Artisan Units are scattered in Different Area. They are functioning under

rented shop and due to availability of lack of space, the placement of machinery &

handling of material with in the unit is not proper.

- Due to frequent power cuts production is hampered.

- There is dearth of quality BDS in the Area of technology, Marketing, Export, Health

& Safety etc.

• Networking among R & D Centre, Technical Training Centre, Testing Centre are not

present in cluster.

Bearing Steel :

The most common material used in the manufacture of bearing rings, balls

and rollers is Alloy steel conforming to specifications SAE 52100. This material hasbecome standard material for the industry all over the world. While the basicmaterial remains the same, the steel manufacturers all over the world have beenimproving this material in order to improve the life span and quality of the bearing.The Indian steel manufacturers although manufacturing steel to specifications SAE52100, are not able to meet the requirement of the bearing manufacturers in so faras purity and oxygen content is concerned. Therefore, bearing SteelManufacturers should be equipped with Vacuum Degassing & Vacuum OxygenDe-Carburising Equipment (LEYBOLD HERAEUS, Germany.) In order tomaintain Oxygen content < 15ppm . The tubes are tested to ensure that the steelis free from injurious imperfections such as piping, cracks, porosity, segregation orinjurious inclusions as referred to in ASTM-381.The inclusion rating is evaluated inaccordance with Plate III of ASTM E-45,The tubes are spheroidized and annealedto ensure that the microstructure consists of spheroidized commentate in a ferritematrix with carbide size conforming to Plates 2 to 4 as per IS 4398-1972 and CG2.1 - 2.3 as per SEP 1520-78.Spherodise annealing and normalising improves themachinability of the annealed hypereutectoid steel and improves its microstructure.To accomplish spherodise annealing and ormalising,temperature controlled energyefficient electrically heated furnace with a capacity of 6,000kg and oil firedfurnaces with capacities of 3,500kg to 4,000kg are being proposed for SME sector.

Forged Bearing Races

1.0 INTRODUCTION : The profile envisage to set up Automatic Hot &Cold Forming Forging Plant to manufacturer Bearing Races .Theoperation of Drilling, parting, and trepanning are not required whileusing Forging Method. The Metallic closed Dies are used in HotForging Method. This method is more suitable and economical forouter Dia of 30 mm and above size.. The Forged Bearing Races areturned /finished on turning Lines.

2.0 MARKET & DEMAND ASPECT : The demand for bearing industry is

derived from demand in two key user segments - automobile andindustrial sector growth. The automobile industry is the largest growth


47/70

47

driver for OEM market as it accounts for almost 45% of total bearingmarket.Engineering sector, which accounts for 28% of total share, holds thesecond growth driver. Considering the high reliance of bearing industryon automobile sector, the fate of bearing industry is largely dependenton production of vehicles.The demand of bearing is also linked to heavy-duty industrialapplication in rolling stock, rolling mills, heavy earth movingequipments and other heavy machinery, accounting for 21% of totalbearing market. However demand in the latter category is met throughimports and therefore does not have significant impact on domesticgrowth .Up Swing in Automobile Sector ,The Indian Automobile sector hasgrown 16.5% in FY03 contributed by export growth of 65.3% and

domestic growth of 14.8%. The automobile industry comprising ofcommercial vehicles, passenger cars, multi-utility vehicles, two/threewheelers and tractors has performed extremely well in FY03. Thesharp growth of this sector has been partly driven by the impact oflower interest rate on demand, intermediated by a competitive financialsector, which has steadily cut prices of automobile loans as interestrates went down.Infrastructure has received a fillip in last 2 years through N-S-E-Wcorridor and Golden Quadrilateral projects. The transformation of road

transport industry through these initiatives will lead to higher demandfor commercial vehicle industry. Passenger cars continue to grow indouble digit driven by rising aspiration levels and easy availability ofcheap finance. Within two wheelers, we expect motorcycle industrygrowth to continue on its growth path.After two bad years, the tractor industry is also likely to witness arevival with completion of inventory correction phase and goodmonsoons likely to drive demand. The positive outlook for auto sectoraugur well for bearings demand and we expect all segment of

automobile industry to report strong growth in the coming year.

Export Potential Exports of bearings companies has increased at a CAGR of 13% inlast seven years from 1995-96 to 2001-02 at Rs2.5bn.Big players inIndian ball and roller bearing have been already exporting a part oftheir production to developed countries like US, Europe etc. Domesticplayers are already sensing the outsourcing opportunity and haveinitiated the process of manufacturing a range of bearings for meetingthe requirements of global customers.The Indian bearing industry, especially the companies havingtechnical/ financial collaboration with global players like SKF Bearings,


48/70

48

FAG Bearings, Timken India, ABC Bearings and NRB Bearings areexpected to garner higher price in export market.The OEM and replacement market control the market dynamics ofBearing. The OEM and replacement market both account for 40% oftotal demand of Bearing Industry individually. The BearingManufacturer are only supplying to replacement market. There is vastmarket of OEM Sector The SSI Bearing Manufacturing units of clusterare mainly supplying to the replacement market of Bearing. On theother hand a number of SSI Races Manufacturing Units are supplyingthe Soft turned Bearing Races to the following large scale units. In theBearing & Bearing component manufacturers cluster Jaipur Approx.10% of Bearing Races are produced by using Forging Method.

sector if they produce standard quality of Bearing.

3.0 RAW MATERIALS : The raw material used in the Manufacturing ofbearing Races is SAE 52100 high Carbon Chrome bearing steel, whichhas composition similar to EN-31 (100 CR 6 As per BIS specification).The raw material for Bearing Races is in the form of Rods The Projectprofile envisage to perform job work of large scale Bearingmanufacturers.

4.0 MANUFACTURING PROCESS & SOURCE OF TECHNOLOGY :Manufacturing process begins by sending hot rolled bar materialthrough Induction Heaters to achieve the proper temperature neededfor forming the part. The material then proceeds into Hatebur 3 stationor 4 station hot former. Depending on the job specifications, thesemachines pancake the part, then form and punch the inside diameterthrough the product. Both machines possess the added feature ofcombination forging, which produces two parts at the same time thusreducing material waste.

At this point, depending on the application, the product can gothrough forge normalizing or spheroidize annealing furnaces, cold ringrolling process, shot blasting or visual inspection areas prior to theshipping area.

4.1 Quality System :

The tests are conducted as per I.S. & A.S.T.M. standards. In the Laboratory, testssuch as Chemical Composition, Including rating, carbide Bending, Grain Size and

other tests are conducted. Once the material s approves after spherodizedAnnealing, it is send for turning process where Inspection of pre-turned races isdone, continuous dimension inspection during turning process,100% CrackDetection testing,100% Visual Inspection for dent, forging spots, rust & Burr ofturned races is done. After getting approval material is transferred for dispatch.

5.0 BASIS OF PROJECT SELECTION : The spurt in prices of the importraw material-steel tubes, has compelled the industry to look for analternative form of material, which has been seen in forged/formedrings.The proposed . Hatebur machines are impressive not only for

their precision and flexibility, but also because of their ability toproduce large volumes of parts at a high production rate which in turnyields good production efficiency. In anticipating future demand &keeping view of global trend only such a plant may be a approvedvendor of large scale bearing manufacturers.The proposed proventechnology has already adopted by M/S Agrasen EngineeringIndustries Limited , Jaipur this technology , running very well , Hence it

justified the project selection.

6.0 PRESUMPTIONS: -(1) To improve the energy efficiency of the plant, it has to runcontinuously.The scheme is based on two shift of 75% efficiency 25 days/monthand 300days per annum(ii) Labour wages has been taken as per market rate. It is likely to vary

depending upon the location of the project .(iii) Rate of interest has been taken 12% on an average on fixed and

working capital. It is likely to vary due to financial outlay and thelocation of the unit.(iv) The operative period of the project is estimated to be about 8 yearsconsidering technology obsolescence.(v) Value of machinery & equipment is estimated on the basisQuotations received & prevailing cost of the local mkt.(vi) As the cost of raw Material is major part of working Capital and isvery high and as per the mrket trend the working capital is being takenfor 1.5 months only.
