Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with eccentric lock have a collar that you twist in one direction to grip and the other to release. Compared to bearings with a set screw, they’re easier to install, require less adjustment over time, and are better for high-speed applications. But, they only work on shafts that spin in one direction.

High-Temperature Mounted Ball Bearings
Synthetic grease or graphite enables these bearings to operate in high temperatures. They have an extended inner ring for additional shaft support. Seals block out dust and contaminants.
Bearings with graphite operate in temperatures up to 660° F, three times that of standard ball bearings, so they're a good choice for use in industrial ovens. However, they’re only for low-speed applications.

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.

Mounted Ball Bearings with Four-Bolt Flange
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Set screw bearings secure to shafts as you tighten their screw. They don’t need a collar, but the screw leaves some marring on shafts. Use them in applications where shafts rotate in both directions.
Eccentric lock bearings are quick to install—twist them in one direction to tighten and the opposite to loosen. They’re better than set screw bearings for high speed applications, but they only work with shafts that rotate in one direction.
