Constant Section (CS) Bearings NC300AR0

Constant Section (CS) Bearings NC300AR0

The NC300AR0 is a constant section bearing with a 30-inch bore and 30.75-inch outer diameter, featuring a slim 0.375-inch width. Made from chrome steel with brass cage, it’s designed for angular contact loads and offers smooth operation.

This bearing handles dynamic radial loads up to 3561 lbf and static radial loads up to 17960 lbf, making it suitable for moderate-speed applications. Its 30° contact angle ensures stable performance under combined loads.

The open design and chromium plating provide durability and easy maintenance. It works in temperatures from -30°C to 110°C and is interchangeable with KAYDON bearings.

Ideal for machinery requiring thin-section bearings, such as robotics or precision equipment. Weighing 3.02 lbs, it’s lightweight yet robust for its size, complying with RoHS standards.
