Constant Section (CS) Bearings KG070AR0

Constant Section (CS) Bearings KG070AR0

The KG070AR0 is a constant section bearing with a 7″ bore and 9″ outer diameter, featuring a slim 1″ width. Made from chrome steel with a brass cage, it’s designed for angular contact loads and handles dynamic radial loads up to 8035 lbf.

Its open design and ABEC-1 tolerance ensure smooth operation, while the 30° contact angle provides stability under thrust and moment loads. The bearing works in temperatures from -30°C to 110°C and comes pre-lubricated for easy use.

This model is interchangeable with KAYDON bearings, making it a versatile choice for replacements. Ideal for applications requiring thin-section bearings, such as robotics or precision machinery.

Weighing 5.87 lbs, it’s robust yet lightweight for its size. Compliant with RoHS standards for safe and reliable performance.
