Clamp-On Collar Ball Bearings
With the clamp-on collar, quickly fasten these bearings to shafts for a concentric, mar-free hold. To centre and lock the shaft in the bearing bore, tighten the lone screw on the locking collar around its inner ring. The tight fit of the collar lessens system noise and vibration. These bearings' steel rings feature a black-oxide coating to help them withstand corrosion.
