About Ball and Roller Bearings

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.

Precision Needle-Roller Bearings

These bearings have higher radial load capacity, speed, and accuracy than standard needle-roller bearings.

Cylindrical Roller Bearings

With cylindrical rollers to distribute load over a large surface area, these bearings are often used to support heavy loads at high speeds in applications such as power generation and metal recycling.

Shaft Liners for Precision Needle-Roller Bearings

Adapt high-precision needle-roller bearings to use on unhardened, unground shafts.

One-Way Locking Needle-Roller Bearing Clutches

The needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. Also known as drawn-cup roller clutches.

Tapered-Roller Bearings

Found anywhere from machine tool spindles to conveyor rollers, these bearings have a two-piece design that allows for adjustment.

Spherical-Roller Bearings

Two rows of rollers give these bearings load capacities over five times higher than comparably sized tapered-roller bearings.

Face-Mount Crossed-Roller Bearings

Mounting holes on the inner and outer rings allow for fastening onto hollow joints and shafts.

Crossed-Roller Bearings

With a considerably larger ID than our Face-Mount Crossed-Roller Bearings, use these to run hydraulic lines, electrical wiring, and other components through the inside of the bearing.

Combination Ball/Needle-Roller Bearings

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle-roller bearing supports radial loads.

Needle-Roller Thrust Bearings

Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings.

Washers for Needle-Roller Thrust Bearings

Adapt needle-roller thrust bearings to use on unhardened, unground surfaces.

Tapered-Roller Thrust Bearings

Thick, tapered rollers stand up to extremely high thrust loads.

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.

High-Load Ball Bearings

Wider than our standard ball bearings, these rugged bearings are good for handling heavy loads at low speeds.

Light Duty Ball Bearings

Use these bearings where high speed and precision are not required.

Precision Ball Bearings

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

Self-Aligning Ball Bearings

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

Hex-Bore Ball Bearings

Mount these bearings onto a hex shaft.

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.

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.

Flanged Ball Bearings

The flange ensures proper positioning inside a tube or housing.

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.

Clamp-On Collar Ball Bearings

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

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.

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.

One-Piece Thrust Ball Bearings

In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

Thrust Ball Bearings

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components.

Thrust Ball Bearings for Shaft Ends

Use these bearings as miniature high-precision turntables. They have a unique design that allows your shaft to sit on top of the bearing rather than being inserted through it.

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 Bearings

Mounted Ball Bearings

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

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.

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.
