Super Precision Angular Contact Ball Bearings 7011 CE/HCP4ADBA

Super Precision Angular Contact Ball Bearings 7011 CE/HCP4ADBA

The 7011 CE/HCP4ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, designed for high-speed applications. Its 15° contact angle and ceramic balls ensure smooth operation under radial loads up to 6210 lbf.

The matched pair arrangement (DB) with extra light preload reduces vibration, making it ideal for machine tools or spindles. The phenolic cage and chrome steel rings offer durability while maintaining low friction.

With a maximum speed of 34,000 RPM, this bearing performs reliably in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees precision for demanding industrial uses.

Weighing 0.72kg, it’s a robust yet lightweight solution for applications requiring high accuracy and speed. The open design allows easy lubrication, extending its service life.
