Constant Section (CS) Bearings KA047AR0

Constant Section (CS) Bearings KA047AR0

The KA047AR0 is a slim, angular contact ball bearing measuring 4.75″×5.25″×0.25″, made from durable chrome steel with a brass cage. It handles radial loads up to 657 lbf and static thrust loads of 1640 lbf, suitable for moderate-speed applications.

Its open design allows easy lubrication, while the 30° contact angle provides stable performance under angular loads. The bearing operates smoothly in temperatures from -30°C to 110°C.

This model is interchangeable with KAYDON bearings, making it a practical choice for replacements. Ideal for precision equipment like robotics or medical devices where space is limited.

Weighing just 0.22 lbs, it’s lightweight yet robust for its thin profile. Compliant with RoHS standards for safe use.
