Super Precision Angular Contact Ball Bearings 7020 CE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 7020 CE/HCP4AQBCA

The 7020 CE/HCP4AQBCA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched set of four bearings for balanced performance.

With a dynamic radial load capacity of 26775 lbf, it handles high speeds up to 20000 RPM smoothly. The ceramic balls and phenolic cage reduce friction, ensuring quiet and efficient operation even under heavy loads.

Its open design allows for easy lubrication, while the extra-light preload (Class A) ensures precise alignment. Ideal for applications like machine tool spindles or high-speed robotics where accuracy is crucial.

The bearing operates reliably in temperatures from -30°C to 110°C and weighs 4.49kg. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for convenient replacements.
