Extra-Clearance Mounted Ball Bearings
Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases. All have a set screw for securing them to shafts without having to use a collar. The screw lets shafts rotate in both directions, so they’re good for applications where you need to reverse.

Easy-Align Mounted Ball Bearings with Two-Bolt Flange
An elongated mounting hole on one side of the flange lets you adjust the position of these bearings without having to remove your shaft. You only need to loosen the bolt instead of removing it to adjust. They’re self-aligning to compensate for shaft misalignment.
