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.

Flanged Screw-Clamp Bushings
A mounting flange prevents movement during tightening. These bushings are 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.

Quick-Grip Flanged Hydraulic Bushings
Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold. Since you don’t have to tighten multiple screw clamps individually, these bushings are quick to adjust and more likely to stay aligned on your shaft. They’re also good for shock loads. A mounting flange prevents movement during tightening. Use a hex key to tighten.
Note: To avoid deforming the sleeve walls, make sure to fully tighten the screw.
Stainless steel bushings have excellent corrosion resistance in most environments.
