Constant Section (CS) Bearings NA047AR0

Constant Section (CS) Bearings NA047AR0

The NA047AR0 is a thin-section angular contact bearing measuring 4.75″ by 5.25″ with a slim 0.25″ width, made from durable chrome steel. It handles radial loads up to 657 lbf and static thrust loads of 1640 lbf, suitable for moderate-speed applications.

Its single-row design with a 30° contact angle ensures smooth operation, while the brass cage adds durability. The open seal type allows for easy lubrication and maintenance.

This bearing is interchangeable with KAYDON models, making it a versatile choice for replacements. Ideal for precision equipment like robotics or medical devices where space and weight are critical.

Weighing just 0.22 lbs, it’s lightweight yet robust. Compliant with RoHS standards, it operates in temperatures from -30°C to 110°C. The chromium plating offers extra corrosion resistance for long-term use.
