FAG Railway Bearings from Ningxia

With approx. 63,000 employees at more than 180 locations worldwide and consolidated

sales of 8.3 billion euros (2006), the Schaeffler Group with its brands INA, LuK and FAG is

a leading global bearing manufacturer and automotive supplier. Its Industrial Division

provides bearing solutions to some 60 different industrial segments via its Production

Machinery, Heavy Industries, Consumer Products and Power Transmission & Railway

business sectors.

An important Schaeffler Group location is FAG Railway Bearing (Ningxia) Co., Ltd.,

located in Yinchuan in the province of Ningxia/China. Here about 500 highly qualified

employees manufacture metric and inch dimension railway axlebox bearings (TAROL units)

of supreme international quality in more than 13,000 square meters of production space.

TAROL bearings are mainly used in locomotives and freight cars. FAG Railway Bearing

(Ningxia) Co., Ltd. also supplies these products to renowned railway system manufac-

turers outside China.

Moreover, the company reconditions used axlebox bearing units, also from various other

manufacturers, which is carried out in a workshop separate from the new bearing pro-

duction. The company’s most important customer is the Chinese Ministry of Railways.

Tapered Roller Bearing Units TAROL

T A R O L U n i t s

TAROL units (Tapered Roller Bearing) are

double row tapered roller bearings that are

supplied with factory-set clearance, greased

and sealed. The TAROL units are thus

supplied ready-to-fit and are pressed onto

the axle journal by means of a hydraulic

device. Individual parts, replacement

parts and housing adapters are available

by agreement.

TAROL units are used for axlebox bearing

arrangements on rail vehicles such as

goods wagons and passenger carriages.

They can be mounted quickly and easily:

The bearing is pressed onto the axle jour-

nal in a single operation and is secured

by means of additional parts and bolts.

Due to the press fit of the unit on an axle

journal of a diameter within the specified

tolerances, the bearing arrangement

achieves the necessary axial clearance.

TAROL units are filled as standard with

greases proven in practice. The greases

in the bearing units of metric dimensions

are certified in accordance with EN 12081.

A relubrication facility can be provided.

Upon request, we can supply TAROL units

with relubrication holes in the end cap or

outer ring. The relubrication holes in the

end caps have a screw plug or a lubrica-

tion nipple. The relubrication intervals are

defined in accordance with the application.

We supply TAROL units in inch dimensions

and metric dimensions for all standardised

axle journals on rail vehicles.
