Constant Section (CS) Bearings NB060AR0

Constant Section (CS) Bearings NB060AR0

The NB060AR0 is a constant section bearing with a 6″ bore and 6.625″ outer diameter, featuring a slim 0.3125″ width. Made from chrome steel with brass cage, it’s designed for angular contact loads and offers smooth operation.

This bearing handles dynamic radial loads up to 1088 lbf and static thrust loads up to 2710 lbf, suitable for moderate-speed applications. Its 30° contact angle provides stability under combined loads.

The open design allows easy lubrication, while the Endura-kote plating enhances durability. It works in temperatures from -30°C to 110°C and meets RoHS standards.

Ideal for precision equipment like robotics or medical devices where space is limited. Interchangeable with KAYDON bearings, it’s a practical choice for replacements or upgrades. Weighing just 0.44 lbs, it’s lightweight yet robust.
