About Ball and Roller Bearings

Mounted Ball Bearings

Ball bearings operate with less friction than other bearings, so they can run at higher speeds.

Low-Profile Mounted Ball Bearings

Designed with a thin, compact housing, these bearings are good for space-constrained applications.

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.

Extra-Clearance Mounted Ball Bearings

Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases.

Permanently Lubricated Mounted Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication.

High-Speed Mounted Ball Bearings

These bearings have the highest speed ratings of any mounted ball bearing that we offer.

Ultra-Corrosion-Resistant Mounted Ball Bearings

Use these bearings in corrosive environments and under water.

Food Industry Mounted Ball Bearings

The lubricant in these mounted ball bearings is NSF registered H1 and FDA compliant for incidental contact with food.

Washdown Mounted Ball Bearings

Meeting IP69K for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants.

Permanently Lubricated Washdown
Compact-Base Mounted Ball Bearings

These bearings are rated IP69K as able to withstand washdown environments such as food, pharmaceutical, and chemical plants. Their fluoropolymer-coated housing is as corrosion resistant as 304 steel and safe for contact with food.

High-Temperature Mounted Ball Bearings

Synthetic grease or graphite enables these bearings to operate in high temperatures.

Insert Bearings

Swap out worn inserts instead of replacing the entire mounted unit.

Mounted Bearings with Three-Bolt Flange

With all three mounting holes on one side, you can position the bearing above or below the mounting surface.

High-Temperature Ball Bearings

Made with either PEEK or graphite, these ball bearings work in applications that are too hot for most other ball bearings.

Mounted Linear Bearings

Corrosion-Resistant Mounted Linear Ball Bearings

Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance.

Adjustable Mounted Linear Ball Bearings

Use the adjustment screw in the housing to tighten or loosen the snugness (also known as preload) of the bearing to your shaft.

Mounted Linear Ball Bearings

Choose ball bearings for debris-free environments and when speed is a necessity. They operate with less friction than sleeve bearings, so you can run them at higher speeds.

High-Load Mounted Linear Ball Bearings

Designed to handle heavy loads, these bearings have the highest load capacities of any mounted linear ball bearings we offer.

Mounted Linear Ball Bearings
for Support Rail Shafts

Mount these bearings on a support rail shaft for applications requiring maximum rigidity.

High-Load Mounted Linear Ball
Bearings for Support Rail Shafts

Designed to handle heavy loads, these bearings have higher load capacities than comparable standard mounted linear ball bearings for support rail shafts.

Corrosion-Resistant Mounted Linear
Ball Bearings for Support Rail Shafts

Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance.
