Constant Section (CS) Bearings SB120AR0

Constant Section (CS) Bearings SB120AR0

The SB120AR0 is a slim stainless steel bearing with a 12-inch bore and 12.625-inch outer diameter, designed for angular contact loads. Its thin 0.3125-inch width makes it ideal for compact spaces, while the stainless steel construction ensures durability.

This single-row bearing handles dynamic radial loads up to 1623 lbf and static loads up to 5840 lbf, with a 30° contact angle for smooth operation. The brass cage enhances performance and longevity, even in temperatures from -30°C to 110°C.

Its open design allows easy lubrication, and the ABEC-1 tolerance ensures reliable precision. The bearing is interchangeable with KAYDON models, offering flexibility for replacements.

Weighing just 0.85 lbs, it’s lightweight yet robust. Suitable for applications requiring slim profiles and angular load handling, such as robotics or precision machinery. Compliant with RoHS standards for safe use.
