Constant Section (CS) Bearings KC090XP0

Constant Section (CS) Bearings KC090XP0

The KC090XP0 is a thin-section ball bearing measuring 9″×9.75″×0.375″, designed for four-point contact loads. Made from chrome steel with a brass cage, it offers a balance of strength and smooth operation.

It handles dynamic radial loads up to 2226 lbf and static thrust loads up to 11270 lbf, making it suitable for moderate to heavy-duty applications. The open design allows for easy lubrication and maintenance.

With a slim profile of just 0.375″ width, it fits neatly into compact spaces without sacrificing performance. Its ABEC-1 tolerance ensures reliable precision for most industrial uses.

Ideal for robotics, medical equipment, or aerospace applications where space is limited but performance is key. Compliant with RoHS standards, it operates smoothly in temperatures from -30°C to 110°C.

Weighing only 0.94 lbs, it’s lightweight yet durable for its size. Interchangeable with KAYDON bearings, it’s a practical choice for replacements or upgrades.
