Constant Section (CS) Bearings NB035AR0

Constant Section (CS) Bearings NB035AR0

The NB035AR0 is a constant section bearing with a 3.5″ bore and 4.125″ 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 radial loads up to 801 lbf and static thrust loads of 1930 lbf, with a 30° contact angle for balanced performance. Its open design allows easy lubrication, while the Endura-kote plating adds durability.

Ideal for applications requiring precise movement, such as robotics or medical equipment. The ABEC-1 tolerance ensures reliable performance in temperatures from -30°C to 110°C.

Weighing just 0.27 lbs, it’s lightweight yet robust, and interchangeable with KAYDON bearings for easy replacements. Compliant with RoHS standards for safe use.
