About Ball and Roller Bearings

Precision Stainless Steel Ball Bearings

Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.

Permanently Lubricated
Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Bearings are 440C stainless steel.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

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 race that eliminates the need for additional lubrication.

Precision Ball Bearings

For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.

Ball Bearings

These steel ball bearings handle higher loads than stainless steel and plastic bearings.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Hex-Bore Ball Bearings

Mount these bearings onto a hex shaft.

Square-Bore Ball Bearings

Mount these bearings onto a square shaft.

Electrically Insulated Ball Bearings

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing.

One-Way Locking Ball Bearing Clutches

Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction.

Tapered Bore Self-Aligning Ball Bearings

For use on tapered shafts and round shafts with adapter sleeves, these ball-bearings have a spherical raceway to compensate for shaft misalignment.

Self-Aligning Ball Bearings

With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.

Flanged Ball Bearings

The flange ensures proper positioning inside a tube or housing.

Precision Flanged Ball Bearings

When speed and accuracy matter most, opt for these bearings. They’re made to tighter tolerances than standard flanged ball bearings.

Self-Aligning Flanged Ball Bearings

No need to worry about precisely aligning these bearings—they swivel to compensate for up to 5° of shaft misalignment.

Flanged Ultra-Thin Ball Bearings

Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.

Set Screw Collar Ball Bearings

Slip these bearings onto a shaft and secure with the included set screws, no special tools required.

Panel-Mount Ball Bearings

Unlike other ball bearings, these do not need to be fully inserted into a housing. A spline around the outside of the bearing creates a permanent, secure hold in thin panels.

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.

Clamp-On Collar Ball Bearings

Quickly secure these bearings onto shafts with the clamp-on collar for a concentric, mar-free hold.

Washdown Set Screw Collar Ball Bearings

Secure these bearings in washdown areas, such as food, beverage, pharmaceutical, and chemical plants, by tightening the set screw onto a shaft—no additional collar needed.

Washdown Clamp-On Collar Ball Bearings

Designed to stand up to frequent washdowns, you can quickly secure these ball bearings onto shafts with the clamp-on collar in food, beverage, pharmaceutical, and chemical plants. The collar centers your shafts and secures them better than set screw ball bearings, which reduces vibration and noise.

Ball Bearings for Combined Loads

High-Speed Angular-Contact Thrust Ball Bearings

An ABEC-7 rating means these bearings are made to some of the tightest tolerances, so they operate at the highest speeds.

Angular-Contact Thrust Ball Bearings

Install these bearings for use with combined radial and thrust loads. They are often used in spindle applications and can be combined with cylindrical roller bearings to better handle radial loads.

Ultra-Thin Ball Bearings

These bearings have twice as many contact points as angular-contact ball bearings.

Mounted Ball Bearings with Two-Bolt Flange

Low-Profile Mounted Ball
Bearings with Two-Bolt Flange

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

High-Speed Mounted Ball
Bearings with Two-Bolt Flange

These bearings have the highest speed ratings of any mounted ball bearing in our offering.

Mounted Ball Bearings with Two-Bolt Flange

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

High-Temperature Mounted Ball
Bearings with Two-Bolt Flange

Synthetic grease enables these bearings to operate in temperatures up to 400° F—nearly double the maximum temperature of standard mounted ball bearings with two-bolt flange.

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.

Permanently Lubricated Washdown
Mounted Ball Bearings with Two-Bolt Flange

Permanently lubricated and IP69K certified for washdown environments, these mounted ball bearings are useful for hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants. Mount them using their two-bolt flange.

Mounted Ball Bearings

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

High-Speed Mounted Ball Bearings

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

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.

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.

High-Temperature Mounted Ball Bearings

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

Permanently Lubricated Mounted Ball Bearings

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

Food Industry Mounted Ball Bearings

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

Mounted Bearings with Three-Bolt Flange

Washdown Mounted Bearings
with Three-Bolt Flange

Rated IP69K for washdowns, these bearings stand up to frequent cleanings in food, beverage, pharmaceutical, and chemical plants.

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.

Mounted Bearings with Four-Bolt Flange

Mounted Roller Bearings with Four-Bolt Flange

The tapered rollers in these bearings support large shafts at high static loads.

Washdown Mounted Ball
Bearings with Four-Bolt Flange

With a four-bolt flange for mounting and an IP69K certification approving them for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants.

High-Temperature Mounted Ball
Bearings with Four-Bolt Flange

Synthetic grease enables these bearings to operate in temperatures up to 400° F—nearly double the maximum temperature of standard mounted ball bearings with four-bolt flange.

Food Industry Mounted Ball
Bearings with Four-Bolt Flange

Mounted Ball Bearings with Four-Bolt Flange

A bolt in each corner makes for a secure, even hold.

High-Speed Mounted Ball
Bearings with Four-Bolt Flange

These bearings have the highest speed ratings of any mounted ball bearing in our offering.

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.

Thread-Mount Bearings

Combine with threaded pipe to mount these bearings in a variety of positions without the need for a flat mounting surface.

Insert Bearings

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