Self-Aligning Ball Bearings
With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open 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.
