Constant Section (CS) Bearings KA065AR0

Constant Section (CS) Bearings KA065AR0

The KA065AR0 is a slim, angular contact ball bearing measuring 6.5″ in bore and 7″ in outer diameter, with a compact width of just 0.25″. Made from chrome steel, it’s lightweight at 0.3 lbs yet handles radial loads up to 788 lbf and thrust loads up to 2000 lbf.

Its open design and brass cage ensure smooth operation, while the 30° contact angle provides stability under combined loads. The bearing works in temperatures from -30°C to 110°C and meets ABEC-1 tolerance standards.

This model is interchangeable with KAYDON bearings, making it a practical choice for replacements. Ideal for applications requiring slim profiles, such as robotics or precision machinery where space is limited.

Compliant with RoHS standards, it comes pre-lubricated for easy installation. The thin section design offers reliable performance without adding bulk.
