Constant Section (CS) Bearings SF250AR0

The SF250AR0 is a constant section bearing measuring 25″×26.5″×0.75″, made from durable stainless steel with a brass cage. It handles angular contact loads and offers a 30° contact angle, suitable for precise applications.

With a dynamic radial load capacity of 9585 lbf and static radial load up to 34700 lbf, it’s built for stability under pressure. The open design allows easy lubrication, and it operates smoothly in temperatures from -30°C to 110°C.

Its thin-section Reali-Slim design saves space without sacrificing strength, making it ideal for compact machinery. The bearing is interchangeable with KAYDON models, simplifying replacements.

Weighing 10.5 lbs, it’s robust yet manageable for its size. Compliant with RoHS standards, it’s a reliable choice for industrial or precision equipment where space and performance matter.
