Ball Bearings
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Food Industry Permanently Lubricated Stainless Steel Ball Bearings

Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and ring that eliminates the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Combination Ball/Needle-Roller Bearings


A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.

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.

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.

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.
