Super Precision Angular Contact Ball Bearings S7011 CB/HCP4ADGA

Super Precision Angular Contact Ball Bearings S7011 CB/HCP4ADGA

The S7011 CB/HCP4ADGA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, measuring 36mm wide. Made from chrome steel with ceramic balls, it offers smooth operation and durability.

This bearing handles radial loads up to 5062 lbf and spins at speeds up to 34,000 RPM, thanks to its phenolic cage and grease lubrication. Its 15° contact angle ensures stable performance under angular loads.

The sealed design keeps contaminants out, while the universal matching allows flexible arrangement (back-to-back, face-to-face, or tandem). It’s interchangeable with SKF bearings for easy replacement.

Ideal for high-speed applications like machine tool spindles or precision equipment. Compliant with P4A tolerance standards, it operates in temperatures from -30°C to 110°C. Weighing 0.8kg, it’s robust yet manageable for its size.
