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.
