Constant Section (CS) Bearings SC300AR0

Constant Section (CS) Bearings SC300AR0

The SC300AR0 is a thin-section angular contact bearing with a 30″ bore and 30.75″ outer diameter, crafted from durable stainless steel. Its slim 0.375″ width makes it ideal for space-constrained applications while handling radial loads up to 3561 lbf.

The single-row design with a 30° contact angle ensures smooth operation under angular loads. The brass cage adds strength, and the open seal allows for easy lubrication.

This bearing suits precision equipment like robotics or medical devices where low friction is key. It operates reliably in temperatures from -30°C to 110°C.

Weighing 3.02 lbs, it’s interchangeable with KAYDON models, offering a practical replacement option. Compliant with RoHS standards for safe use.
