About Ball and Roller Bearings

More

Ultra-Thin Ball Bearings

Open

Shielded

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.

440 stainless steel bearings are more corrosion resistant than steel bearings.

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.
