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

Mounted Roller Bearings
Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.
Sealed bearings block out dust and contaminants.
