Super Precision Angular Contact Ball Bearings S7011 CB/HCP4ADBA

Super Precision Angular Contact Ball Bearings S7011 CB/HCP4ADBA

The S7011 CB/HCP4ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 5062 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, 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 stability under angular loads. Suitable for machine tools or high-speed spindles where accuracy is key.

Weighing 0.8kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for exceptional precision.
