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.
