Constant Section (CS) Bearings NC080AR0

Constant Section (CS) Bearings NC080AR0

The NC080AR0 is a thin-section angular contact bearing with an 8-inch bore and 8.75-inch outer diameter, featuring durable chrome steel construction. Its compact 0.375-inch width makes it ideal for space-saving designs, while the brass cage ensures smooth operation.

This bearing handles radial loads up to 1708 lbf and static thrust loads of 4300 lbf, suitable for moderate-speed applications. The 30° contact angle provides stable performance under combined loads.

Its open design allows easy lubrication, and the chromium plating offers extra corrosion resistance. The bearing operates in temperatures from -30°C to 110°C.

Interchangeable with KAYDON models, it’s a practical choice for industrial machinery or robotics where precision and slim profiles are needed. Weighing just 0.84 lbs, it balances strength with lightweight design.
