Super Precision Angular Contact Ball Bearings S71912 CE/P4ADBA

Super Precision Angular Contact Ball Bearings S71912 CE/P4ADBA

The S71912 CE/P4ADBA is a super precision angular contact ball bearing with a 60mm bore and 85mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 5962 lbf and spins smoothly at speeds up to 32,500 RPM.

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

This matched set of two bearings (DB arrangement) offers stable performance under angular loads. Suitable for machine tools or high-speed spindles where accuracy is key.

Weighing 0.37kg, it operates in temperatures from -30°C to 110°C. Compliant with P4A tolerance class for exceptional precision.
