Constant Section (CS) Bearings KC045XP0

Constant Section (CS) Bearings KC045XP0

The KC045XP0 is a thin-section ball bearing with a compact design, measuring 4.5″ in bore and 5.25″ in outer diameter. Its slim 0.375″ width makes it ideal for space-constrained applications, while the chrome steel construction ensures durability.

This four-point contact bearing handles radial loads up to 1510 lbf and thrust loads up to 2380 lbf, performing well in various orientations. The brass cage provides smooth operation, and it’s pre-lubricated for easy use straight out of the box.

With an ABEC-1 tolerance class, it offers reliable precision for moderate-speed applications. The open design allows for simple maintenance and inspection.

Suitable for robotics or precision machinery, it operates in temperatures from -30°C to 110°C. Weighing just 0.48 lbs, it’s lightweight yet robust. Compliant with RoHS standards, it’s interchangeable with KAYDON bearings for easy replacement.
