Super Precision Angular Contact Ball Bearings 7011 CDGA/HCP4A

Super Precision Angular Contact Ball Bearings 7011 CDGA/HCP4A

The 7011 CDGA/HCP4A is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from chrome steel for durability. Its 15° contact angle and ceramic balls ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 8932 lbf and spins at speeds up to 34,000 RPM, thanks to its phenolic cage and lubricated design. The extra-light preload (Class A) enhances precision in high-speed applications.

With a temperature range of -30°C to 110°C, it suits demanding environments. The P4A tolerance class guarantees exceptional accuracy. Ideal for machine tools or high-performance spindles where precision is key.

Weighing 0.32kg, it’s available in matched sets for universal mounting (back-to-back, face-to-face, or tandem). Interchangeable with SKF bearings for easy replacement.
