Constant Section (CS) Bearings KA075AR0

Constant Section (CS) Bearings KA075AR0

The KA075AR0 is a slim, angular contact ball bearing with a 7.5″ bore and 8″ outer diameter, designed for precision applications. Its thin 0.25″ width and open construction make it ideal for compact spaces while handling radial loads up to 857 lbf.

Made from durable chrome steel with a brass cage, it offers smooth operation and long service life. The 30° contact angle efficiently manages combined loads, including static thrust up to 2190 lbf.

This bearing is interchangeable with KAYDON models, providing a reliable alternative. Suitable for use in robotics or medical equipment where space and precision are key.

It operates in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation. Compliant with RoHS standards, it weighs just 0.34 lbs for easy handling.
