Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.

Bearing with concentric lock use adapter sleeves (sold separately) to lock onto shafts in a way that enables high running speeds with little vibration. They work for applications that require reversing because they allow shafts to rotate in both directions.
