Super Precision Angular Contact Ball Bearings 7011 ACE/HCP4ALDGA

Super Precision Angular Contact Ball Bearings 7011 ACE/HCP4ALDGA

The 7011 ACE/HCP4ALDGA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 5850 lbf and spins smoothly at speeds up to 34,000 RPM.

Its 25° contact angle and ceramic balls reduce friction, while the phenolic cage ensures quiet operation. The bearing comes pre-lubricated and works in temperatures from -30°C to 110°C.

Designed for universal matching, it can be arranged back-to-back, face-to-face, or tandem. Ideal for high-precision applications like machine tools or spindle drives.

Weighing 0.72kg, it’s a robust yet lightweight choice. Compliant with P4A tolerance standards for exceptional accuracy.
