Constant Section (CS) Bearings NF250AR0

Constant Section (CS) Bearings NF250AR0

The NF250AR0 is a constant section bearing with a 25″ bore and 26.5″ outer diameter, featuring a slim 0.75″ width. Made from chrome steel with brass cage, it’s built for durability and smooth operation.

This angular contact bearing handles radial loads up to 9585 lbf and static thrust loads of 26100 lbf, making it suitable 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 extra corrosion resistance. It operates well in temperatures from -30°C to 110°C.

Ideal for industrial machinery or robotics where space is limited but high load capacity is needed. Compliant with RoHS standards, it’s a reliable choice for replacements, interchangeable with KAYDON bearings. Weighing 10.5 lbs, it balances strength and manageability.
