Constant Section (CS) Bearings NB110AR0

The NB110AR0 is a thin-section angular contact bearing with an 11″ bore and 11.625″ outer diameter, featuring a compact width of just 0.3125″. Made from chrome steel with a brass cage, it’s built for durability and smooth operation.

This bearing handles radial loads up to 1540 lbf and static thrust loads of 4000 lbf, with a 30° contact angle for balanced performance. Its open design allows easy lubrication, and it operates smoothly in temperatures from -30°C to 110°C.

The Endura-kote plating adds extra corrosion resistance, while the ABEC-1 tolerance ensures reliable precision. Ideal for applications like robotics or aerospace where space is limited but performance is key.

Weighing only 0.78 lbs, it’s lightweight yet robust. Compliant with RoHS standards, it’s interchangeable with KAYDON bearings for easy replacements.
