Constant Section (CS) Bearings NC042AR0

Constant Section (CS) Bearings NC042AR0

The NC042AR0 is a constant section bearing measuring 4.25″×5″×0.375″, made from durable chrome steel with a brass cage. It handles angular contact loads with a 30° contact angle and supports radial loads up to 1194 lbf.

Its thin-section design and open construction make it easy to maintain, while the chromium plating adds extra corrosion resistance. The bearing operates smoothly in temperatures from -30°C to 110°C.

This model is interchangeable with KAYDON bearings, offering a reliable replacement option. Ideal for applications requiring precise motion control, such as robotics or medical equipment.

Weighing just 0.46 lbs, it’s lightweight yet robust for its size. Compliant with RoHS standards for safe use.
