About Ball and Roller Bearings

Ball Bearings

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

Precision Ball Bearings

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

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

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.

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.

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.

Low-Profile Mounted Ball Bearings

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

Permanently Lubricated Mounted Ball Bearings

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