Super Precision Angular Contact Ball Bearings 7020 CE/HCP4ADBA

Super Precision Angular Contact Ball Bearings 7020 CE/HCP4ADBA

The 7020 CE/HCP4ADBA is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-quality chrome steel and ceramic balls. It handles radial loads up to 16380 lbf and reaches speeds of 20,000 RPM, making it suitable for high-performance applications.

Its 15° contact angle and matched arrangement (2 bearings DB) provide excellent stability and precision. The phenolic cage ensures smooth operation, while the extra-light preload (Class A) reduces friction.

This bearing is ideal for machine tools or spindle systems where accuracy is crucial. It operates in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation.

Weighing 2.25kg, it’s robust yet manageable. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for convenient replacements.
