Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
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.

Make up for imperfections and gaps between your bearing and shaft for a tight fit. These bearing adapter sleeves are the most common way to mount a bearing with a tapered bore onto a cylindrical seat. They work with both straight and stepped shafts. Secure using the included lock nut.
