Constant Section (CS) Bearings KF120BR0K

Constant Section (CS) Bearings KF120BR0K

The KF120BR0K is a constant section bearing measuring 12″×13.5″×0.75″, made from durable chrome steel with a brass cage. It handles angular contact loads and fits into tight spaces thanks to its slim design.

With a 30° contact angle, it supports radial loads up to 6487 lbf and static thrust loads up to 16290 lbf. Its open design allows for easy lubrication and maintenance.

This bearing operates smoothly in temperatures from -30°C to 110°C. It’s interchangeable with KAYDON bearings, making it a versatile choice for replacements.

Ideal for applications requiring precision and space efficiency, such as robotics or medical equipment. Weighing 5.2 lbs, it’s robust yet manageable for its size. Compliant with RoHS standards for safe use.
