About Ball and Roller Bearings

Open

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.
