Set Screw Collar Ball Bearings
Slip these bearings onto a shaft and secure with the included set screws, no special tools required. All have an extended inner ring for additional shaft support.
Bearings with a black-oxide steel ring have some corrosion resistance.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.

Clamp-On Collar Ball Bearings
Quickly secure these bearings onto shafts with the clamp-on collar for a concentric, mar-free hold. Tighten the single screw on the locking collar around its inner ring on your shaft to center and secure the shaft in the bearing bore. The collar’s firm grip reduces vibration and noise in your system. The steel rings on these bearings have a black-oxide finish for some corrosion resistance.

Washdown Set Screw Collar Ball Bearings
Secure these bearings in washdown areas, such as food, beverage, pharmaceutical, and chemical plants, by tightening the set screw onto a shaft—no additional collar needed. Similar to 304 stainless steel, the nickel-coated steel rings on these bearings won’t break down from water. The extended inner ring increases shaft support. All of these bearings have NSF registered H1 lubrication, which is certified for incidental contact with food.
