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.
Bearings with nickel-plated cast iron housing are more corrosion resistant and durable than bearings with a cast iron housing.

Low-Profile Mounted Ball Bearings with Two-Bolt Flange
Designed with a thin, compact housing, these bearings are good for space-constrained applications. Seals block out dust and contaminants.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.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.
Self-aligning bearings compensate for shaft misalignment.

Food Industry Mounted Ball Bearings with Two-Bolt Flange
The lubricant in these mounted ball bearings is NSF registered H1 and FDA compliant for incidental contact with food. Bearings are self-aligning to compensate for shaft misalignment.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.
Stainless steel bearings are more corrosion resistant than steel bearings.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Extreme-Temperature Dry-Running Mounted
Sleeve Bearings with Two-Bolt Flange
Capable of handling temperatures from -400° to 750° F, these graphalloy bearings have the widest temperature range of any of our mounted bearings. They are self-aligning to compensate for shaft misalignment.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.
