Constant Section (CS) Bearings NG055AR0

Constant Section (CS) Bearings NG055AR0

The NG055AR0 is a constant section bearing measuring 5.5″ by 7.5″ with a slim 1″ width, made from durable chrome steel. Its angular contact design handles radial loads up to 7192 lbf and static thrust loads of 16240 lbf, suitable for moderate-speed applications.

The brass cage ensures smooth operation, while the open seal allows easy lubrication. With a 30° contact angle, it manages combined loads effectively in temperatures from -30°C to 110°C.

This bearing is interchangeable with KAYDON models, offering a reliable alternative. Its chromium plating adds corrosion resistance, ideal for machinery requiring thin-section bearings.

Weighing 4.73 lbs, it’s robust yet compact for its size. Compliant with RoHS standards, it’s a practical choice for industrial equipment or precision mechanisms.
