High-performance seal

Bonded nitrile rubber seal with an engineered interface to the inner ring.

Lubrication delivery system

precision-machined lubrication groove and holes in the outer ring of the bearing.

Precision formed flinger

provides the first level of protection against contamination.

Hardened and ground seal land

Helps protect against abrasive wear, extending seal life.

Outer ring with spherical outside diameter

engineered fit between bearing and housing to improve bearing life.

Wide inner ring

improved shaft support over narrow rings, improving bearing life and reducing misalignment.

Cast-iron housing incorporates iso 185 grade 200 (astm a48 class no. 30) cast iron.

Engineered balls and cage

steel cage provides effective ball guidance and high temperature service capability.

Set screw angle

120-degree angle minimizes inner ring distortion for smoother-running bearing.

1. Ensure that the shaft is clean, free from burrs, straight and of proper diameter. The bearing should not be mounted on a worn section of the shaft. Using shafts with hardnessgreaterthanhRC45willreduceeffectiveness oflockingdevices.Seetable2onpage9forsuggested shaft tolerances.

2. Installthesuppliedgrease fitting into the threaded lubrication hole on the housing. Align the bearing in its housing and slide the unit into position on the shaft.

3. boltthehousingtightlytoits mounting supports using an appropriately sized fastener and suggested bolt torque (table4onpage9).Flat washers should be used when installing any kind of housed unit. Washers should be properly sized to bolt diameter.

4.Lockthebearingtotheshaft by tightening each inner ring set screw incrementally to suggested torque levels(table3onpage9).

Ball bearing housed units are available in a wide variety of sizes and housing styles to accommodate a complete range of operating conditions.

These units generally have cast-iron housings and are designed for mounting on straight shafts with a slip fit. The set screw locking mechanism provides ease in mounting.

INSTALLATION

for additional timken product warnings, visit www.timken.com/warnings.

Failure to observe the following warnings could create a risk of death or serious injury.

Proper maintenance and handling practices are critical. Always follow installation instructions and maintain

proper lubrication.

Overheated bearings can ignite explosive atmospheres. Special care must be taken to properly select, install,

maintain and lubricate housed unit bearings that are used in or near atmospheres that may contain explosive levels of combustible gases or accumulations of dust such as grain,

coal, or other combustible materials. Consult your equipment designer or supplier for installation and

maintenance instructions.

Do not use excessive force when mounting or dismounting the unit.

Follow all tolerance, fit and torque recommendations.

Always follow the Original Equipment Manufacturer’s installation and maintenance guidelines.

Ensure proper alignment.

Never weld housed units.

Do not heat components with an open flame.

Do not operate at bearing temperatures above 121°C (250°F).

warning

Failure to follow these cautions may result in property damage.

If hammer and bar are used for installation or removal of a part, use a mild steel bar (e.g., 1010 or 1020 grade). Mild steel bars are less likely to cause release of high-speed fragments from the hammer or bar or the part being installed or removed.

Do not use damaged housed units.

The following tables provide useful installation details related to shaft tolerance and torque for set screws and bolts.

TECHNICAL DATA
