Constant Section (CS) Bearings SA055AR0

Constant Section (CS) Bearings SA055AR0

The SA055AR0 is a slim, stainless steel angular contact bearing measuring 5.5″ in bore and 6″ in outer diameter, with a thin 0.25″ width. Its stainless steel construction and brass cage offer durability and smooth operation.

Designed for angular loads, it handles radial loads up to 715 lbf and static thrust loads of 1800 lbf. The 30° contact angle ensures stable performance in demanding applications.

This open-type bearing is easy to maintain and works in temperatures from -30°C to 110°C. It’s interchangeable with KAYDON models, making replacements straightforward.

Ideal for precision equipment where space is limited, such as robotics or medical devices. Compliant with RoHS standards and weighing just 0.25 lbs, it’s both lightweight and reliable.
