Constant Section (CS) Bearings KB080AR0

The KB080AR0 is a slim, angular contact ball bearing with an 8-inch bore and 8.625-inch outer diameter, crafted from durable chrome steel. Its compact 0.3125-inch width makes it ideal for space-saving designs while handling radial loads up to 1284 lbf.

With a 30° contact angle, it manages thrust loads effectively, supporting up to 3260 lbf statically. The open design and brass cage ensure smooth operation and easy maintenance.

This bearing suits applications requiring precise angular contact, such as robotics or medical equipment. Its ABEC-1 tolerance and thin section design offer reliable performance in tight spaces.

Weighing just 0.57 lbs, it’s lightweight yet robust. Compliant with RoHS standards, it operates smoothly in temperatures from -30°C to 110°C. Interchangeable with KAYDON models, it’s a practical choice for replacements.
