Constant Section (CS) Bearings NG250AR0

Constant Section (CS) Bearings NG250AR0

The NG250AR0 is a constant section bearing with a 25″ bore and 27″ outer diameter, featuring a slim 1″ width. Made from chrome steel with a brass cage, it’s designed for angular contact loads and offers smooth operation.

This bearing handles dynamic radial loads up to 15239 lbf and static loads up to 49280 lbf, making it robust for heavy-duty applications. Its 30° contact angle ensures stable performance under combined loads.

The open design allows easy lubrication, while the chromium plating adds corrosion resistance. It operates in temperatures from -30°C to 110°C, suitable for varied environments.

Ideal for machinery requiring precise motion control, like robotics or industrial equipment. Compliant with RoHS standards, it’s interchangeable with KAYDON bearings for convenient replacements.
