Constant Section (CS) Bearings ND042AR0

Constant Section (CS) Bearings ND042AR0

The ND042AR0 is a constant section bearing measuring 4.25″×5.25″×0.5″, designed for angular contact loads. Made from durable chrome steel with a brass cage, it handles radial loads up to 1876 lbf and static thrust loads up to 4420 lbf.

Its thin-section design with Endura-kote plating offers smooth operation, while the 30° contact angle ensures stability under moment loads. The open seal type allows for easy lubrication and maintenance.

This bearing is interchangeable with KAYDON models, making it a versatile choice for replacements. Ideal for applications requiring precise angular contact, such as robotics or medical equipment.

Weighing just 0.84 lbs, it’s lightweight yet robust, with a temperature range of -30°C to 110°C. Compliant with RoHS standards for safe use.
