About Ball and Roller 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.

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.

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.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good 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.

Precision Stainless Steel Ball Bearings

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

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

Plastic Ball Bearings

Made of slippery plastic, these bearings do not require lubrication and have excellent corrosion and chemical resistance.

High-Load Plastic Ball Bearings

With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings.

Water-Resistant Plastic Ball Bearings

Made of PVDF, these bearings resist moisture absorption, so they won’t warp in underwater applications.

High-Temperature Plastic Ball Bearings

These PEEK bearings operate in temperatures almost twice as high as our other plastic ball bearings.

Flanged Ball Bearings

The flange ensures proper positioning inside a tube or housing.

Lubrication-Free Plastic Flanged Ball Bearings

Install these acetal bearings in caustic environments and where lubrication can’t be used. They have good all-around corrosion and chemical resistance.

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.

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.

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.

Low-Profile Mounted Ball Bearings

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