Constant Section (CS) Bearings NC180AR0

The NC180AR0 is a constant section bearing with an 18″ bore and 18.75″ outer diameter, featuring a slim 0.375″ width. Made from chrome steel with a brass cage, it’s built for durability and smooth operation.

This angular contact bearing handles radial loads up to 2707 lbf and static thrust loads of 7280 lbf, making it suitable for moderate-speed applications. Its 30° contact angle provides stable performance under combined loads.

The open design and chromium plating (Endura-kote) offer corrosion resistance while allowing easy maintenance. It’s interchangeable with KAYDON bearings, simplifying replacements.

Ideal for machinery requiring thin-section bearings, such as robotics or precision equipment. Works in temperatures from -30°C to 110°C and meets RoHS standards. Weighs 1.83 lbs for easy handling.
