Constant Section (CS) Bearings K08020AR0

Constant Section (CS) Bearings K08020AR0

The K08020AR0 is a slim, angular contact ball bearing measuring 80mm by 120mm by 20mm, crafted from durable chrome steel. It handles radial loads up to 3785 lbf and static thrust loads up to 8201 lbf, with a smooth operation up to 110°C.

Its single-row design and open seal make it easy to maintain, while the brass cage ensures reliable performance. The 30° contact angle provides stability for angular loads.

This bearing is interchangeable with KAYDON models, ideal for compact machinery or precision equipment where space is limited. Its lightweight 0.69kg build suits applications needing both strength and a slim profile.

Compliant with RoHS standards, it’s a practical choice for industrial or automation settings requiring consistent performance.
