Constant Section (CS) Bearings NF070AR0

Constant Section (CS) Bearings NF070AR0

The NF070AR0 is a constant section bearing with a 7″ bore and 8.5″ outer diameter, featuring a slim 0.75″ width. Made from durable chrome steel, it’s designed for angular contact loads and offers smooth operation.

Its brass cage ensures reliable performance, while the open design allows for easy maintenance. The bearing handles radial loads up to 4932 lbf and static thrust loads up to 11770 lbf, making it robust for various applications.

With a 30° contact angle and ABEC-1 tolerance, it provides precise movement. The chromium plating adds extra durability, and it operates well in temperatures from -30°C to 110°C.

Ideal for machinery requiring thin-section bearings, such as robotics or precision equipment. It’s interchangeable with KAYDON models, offering flexibility for replacements. Weighing 3.16 lbs, it balances strength and lightweight design.
