Shaft Locking Styles

Set screw locking bearing Eccentric locking collar bearing Adapter sleeve locking bearing
Set Screw Locking

The industry standard for bearing mounting. Two set screws on the bearing inner race are tightened to grip the shaft to achieve a secure hold.

Eccentric Locking Collar

A collar with an off-center counter-bored recess. When mated with the bearing race and twisted, locks to the shaft without screws.

Adapter Sleeve Locking

A tapered sleeve is placed on the shaft and driven up into the bearing bore creating an interference fit. The sleeve is tightened and secured with a large nut. This design is ideal for preventing fretting on high speed equipment such as fans and blowers.



Housings

Flanges for every application

2-Bolt Pillow Block 2-Bolt Flange 4-Bolt flange Piloted Flange 3-Bolt Bracket Tap Base Pillow Block
Grey Cast Iron

The standard housing: 35 ksi grey cast iron with an enamel paint exterior finish, machined with a precise H7 bearing seat. Provides reliable service for most industrial applications.

304 Cast Stainless Steel

Manufactured with extra smooth walls that will shed contamination and resist rust, machined with a precise H7 bearing seat. Provides excellent corrosion resistance and strength that will not be compromised by chipping, scratching or heating of the surface.

Split Cast Ductile Iron

Maximum strength and durability in a split 65-45-12 ductile iron casting and a precise H7 bearing seat. The split design allows for rapid exchange of the bearing without the need to reset the flange alignment. Ductile iron naturally weathers and resists further oxidation for long term service in harsh conditions.

Special Treatment Options

Custom Grease For Sealed Bearings

User-selected or recommended grease applied to new bearings - ready to go out of the box.

Dry Carbon Solid Lubrication

Dry, non-stick, high temperature lubrication, rated for service from -250°F to 660°F. Available for most ball bearings with a metal cage separating the balls or rollers. Learn More

Anti Corrosion/Anti-Wear Treatment

Steel nitriding and sealing, a hard ceramic case for all bearings surfaces that self-lubricates and resists scuffing, micro-welding, corrosion, and particulate abrasion. Provides a significant service life extension when poor lubrication, liquid corrosives, start/stop rotation, or high temperatures are present. Learn More
