About Ball and Roller Bearings

Combination Ball/Needle-Roller Bearings
A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.

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. Bearings take on the shape of their housing and may be oblong prior to installation.
Open bearings dissipate heat more efficiently than sealed bearings.

Precision Needle-Roller Bearings
Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
Sealed bearings block out dust and other contaminants.
Shaft liners allow you to use the bearing on unhardened and unground shafts.
