Constant Section (CS) Bearings SB042AR0

Constant Section (CS) Bearings SB042AR0

The SB042AR0 is a slim stainless steel bearing measuring 4.25″ in bore and 4.875″ in outer diameter, with a compact width of just 0.3125″. It’s designed for angular contact loads and fits snugly in tight spaces.

Made from durable stainless steel with a brass cage, it handles dynamic radial loads up to 891 lbf and static loads up to 2150 lbf. Its 30° contact angle provides stable performance under combined loads.

This open-design bearing is easy to maintain and works in temperatures from -30°C to 110°C. It’s interchangeable with KAYDON models, making it a versatile choice for replacements.

Ideal for precision applications like robotics or medical equipment where slim profiles and reliable performance are key. Compliant with RoHS standards, it’s a safe and practical option.

Weighing only 0.31 lbs, it’s lightweight yet sturdy for its size. The ABEC-1 tolerance ensures smooth operation without unnecessary complexity.
