Precision Needle-Roller Bearings
 |  |
Bearing |
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.
Shaft Liners—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.

Corrosion-Resistant Flanged Screw-Clamp Bushings
 |  |
Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Nickel-Plated Steel—Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.
Stainless Steel—Stainless steel bushings have excellent corrosion resistance and can withstand prolonged exposure to moisture.
