Constant Section (CS) Bearings KB035AR0

Constant Section (CS) Bearings KB035AR0

The KB035AR0 is a slim, open-type angular contact ball bearing measuring 3.5″ in bore and 4.125″ in outer diameter, with a compact width of just 0.3125″. Made from chrome steel, it’s designed for angular loads and offers smooth operation.

This bearing handles radial loads up to 801 lbf and static thrust loads up to 1930 lbf, with a 30° contact angle for stability. Its brass cage ensures durability, while the ABEC-1 tolerance class provides reliable precision.

The open design allows easy lubrication, and it works in temperatures from -30°C to 110°C. Weighing only 0.27 lbs, it’s lightweight yet robust.

Ideal for applications requiring slim profiles, such as robotics or precision machinery. Compliant with RoHS standards, it’s interchangeable with KAYDON bearings for easy replacement.
