Compact-Base Mounted Ball Bearings
Also known as tapped-base bearings, these ball bearings mount to surfaces from the bottom through threaded holes. Because of their narrow profile, they’re commonly used in tight-clearance spaces, including systems where multiple shafts are mounted close together.
Set screw shaft-mount bearings secure to shafts when you tighten the set screw, with no need for an additional collar. Set screws cause some amount of marring on shafts.

High-Speed Oil-Embedded Mounted Sleeve Bearings
A strong steel housing allows these bearings to handle higher speeds than standard oil-embedded mounted sleeve bearings. Startup friction causes the bearing to release a thin layer of oil on the bearing’s surface.
Bearings with an oil cup have a reservoir that distributes additional oil onto the bearing. A self-closing hinged cover keeps out contaminants.
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.

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.

Permanently Lubricated Washdown Mounted Ball Bearings with Four-Bolt Flange
Made to withstand frequent washdowns, these bearings are permanently lubricated, which means you’ll never have to add lubricant. Use them in hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants. With a 316 stainless steel housing, these bearings won’t rust from salt water, chlorine, or chemicals. All are lubricated with NSF registered H1 grease, which is certified for incidental contact with food.
Set-screw bearings secure to shafts as you tighten their screw. They don’t need a collar; however, the screws leave some marring on the shaft.
Concentric-lock bearings have a collar that centers and secures the shaft in the bearing bore. To install, tighten the single screw on the collar around its inner ring on your shaft. These bearings have a secure grip on the shaft that reduces vibration and noise.
