High-Load Tapered-Roller Bearings
Double rows of tapered bearings support large shafts with heavy loads. They also handle thrust loads in either direction as well as radial loads. All come assembled and ready to use.

Precision Needle-Roller Bearings
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Open bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants.
Shaft liners allow you to use the bearing on unhardened and unground shafts.

Self-Centering Screw-Clamp Bushings
A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.
