Super Precision Angular Contact Ball Bearings S7011 CD/P4ADBA

Super Precision Angular Contact Ball Bearings S7011 CD/P4ADBA

The S7011 CD/P4ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 14332 lbf and spins smoothly at speeds up to 34000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 15° contact angle and extra-light preload make it ideal for high-precision applications.

This matched pair (DB arrangement) offers excellent stability under angular loads. Suitable for machine tools or spindle drives where accuracy and low friction are key.

Weighing 0.76kg, it operates in temperatures from -30°C to 110°C. Compliant with P4A tolerance class for superior performance.
