Super Precision Angular Contact Ball Bearings S71911 CD/P4ADT

Super Precision Angular Contact Ball Bearings S71911 CD/P4ADT

The S71911 CD/P4ADT is a super precision angular contact ball bearing with a 55mm bore and 80mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 7020 lbf and spins smoothly at speeds up to 34,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 15° contact angle and matched arrangement (2 bearings) provide stability for high-precision applications.

This bearing is preloaded for better performance and fits systems requiring P4A tolerance. Ideal for machine tools or spindles where accuracy and speed are crucial.

Weighing 0.37kg, it’s robust yet compact. Works in temperatures from -30°C to 110°C and is interchangeable with SKF models for easy replacement.
