Super Precision Angular Contact Ball Bearings S7020 ACD/P4ATBTB

Super Precision Angular Contact Ball Bearings S7020 ACD/P4ATBTB

The S7020 ACD/P4ATBTB is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, measuring 72mm in width. Made from high-quality chrome steel, it’s designed for angular contact loads and comes in a matched set of three bearings.

With a 25° contact angle and sealed design, it handles dynamic radial loads up to 38700 lbf and spins smoothly at speeds up to 16250 RPM. The phenolic cage ensures durability and reduces friction.

Its light preload (Class B) and P4A tolerance class make it ideal for high-precision applications like machine tools or spindle drives. The sealed design keeps grease in and contaminants out, extending its lifespan.

Weighing 3.82kg, this bearing operates in temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings, offering a reliable alternative for precision machinery.
