Constant Section (CS) Bearings ND055AR0

Constant Section (CS) Bearings ND055AR0

The ND055AR0 is a constant section bearing measuring 5.5″×6.5″×0.5″, made from durable chrome steel with a brass cage. It handles angular contact loads and fits inch-based systems, interchangeable with KAYDON models.

With a 30° contact angle, it supports dynamic radial loads up to 2145 lbf and static thrust loads up to 5160 lbf. Its ABEC-1 tolerance ensures reliable performance, while the open design allows easy lubrication.

The thin-section Endura-kote plating reduces friction and extends lifespan. It operates smoothly in temperatures from -30°C to 110°C, making it versatile for various conditions.

Ideal for applications requiring precise angular contact, such as robotics or rotary tables. Its lightweight design (1.06 lbs) and chromium-plated surface offer a balance of strength and corrosion resistance.
