Constant Section (CS) Bearings NC140AR0

Constant Section (CS) Bearings NC140AR0

The NC140AR0 is a constant section bearing measuring 14″ by 14.75″ with a slim 0.375″ width, made from durable chrome steel. It handles angular contact loads with a 30° contact angle and supports radial loads up to 2347 lbf.

Its open design and brass cage ensure smooth operation, while the chromium plating adds extra corrosion resistance. The bearing works in temperatures from -30°C to 110°C and comes pre-lubricated for easy use.

This model is interchangeable with KAYDON bearings, making it a practical choice for replacements. Ideal for applications requiring thin-section bearings, such as robotics or precision machinery.

Weighing 1.43 lbs, it’s lightweight yet sturdy. Compliant with RoHS standards for safe and reliable performance.
