Mounted Ball Bearings with Two-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with a set-screw shaft mount secure to shafts with no need for an additional collar. They can be used for bi-directional shaft rotation when applications require reversing action. The set screw may cause some marring on the shaft.
Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction.

High-Temperature Mounted Ball Bearings with Two-Bolt Flange
Synthetic grease enables these bearings to operate in temperatures up to 400° F—nearly double the maximum temperature of standard mounted ball bearings with two-bolt flange. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
