Constant Section (CS) Bearings KF250XP0

Constant Section (CS) Bearings KF250XP0

The KF250XP0 is a thin-section ball bearing with a 25″ bore and 26.5″ outer diameter, designed for four-point contact loads. Its compact 0.75″ width makes it ideal for space-constrained applications, while the chrome steel construction ensures durability.

This bearing handles dynamic radial loads up to 11909 lbf and static thrust loads up to 72650 lbf, suitable for heavy-duty machinery. The brass cage provides smooth operation, and it works in temperatures from -30°C to 110°C.

Its open design allows easy lubrication, and it meets RoHS standards for safety. The bearing is interchangeable with KAYDON models, offering flexibility for replacements.

Weighing 10.9 lbs, it’s a robust choice for applications like robotics or aerospace where precision and strength are key. The ABEC-1 tolerance ensures reliable performance in demanding conditions.
