Constant Section (CS) Bearings NB180AR0

Constant Section (CS) Bearings NB180AR0

The NB180AR0 is a constant section bearing with an 18″ bore and 18.625″ outer diameter, featuring a slim 0.3125″ width. Made from chrome steel with brass cage, it’s built for angular contact loads and offers smooth operation.

This bearing handles dynamic radial loads up to 2038 lbf and static loads up to 8660 lbf, with a 30° contact angle for stability. Its open design allows easy lubrication, and it works in temperatures from -30°C to 110°C.

The thin-section design saves space without sacrificing strength, while the chromium plating adds corrosion resistance. It’s interchangeable with KAYDON bearings, making replacements straightforward.

Ideal for applications requiring precise motion control, like robotics or aerospace systems. Weighing 1.26 lbs, it’s lightweight yet durable for its size. Compliant with RoHS standards for safe use.
