Super Precision Angular Contact Ball Bearings 7220 CD/HCP4ADGA

Super Precision Angular Contact Ball Bearings 7220 CD/HCP4ADGA

The 7220 CD/HCP4ADGA is a super precision angular contact ball bearing with a 100mm bore and 180mm outer diameter, crafted from durable chrome steel. Its 15° contact angle and ceramic balls ensure smooth operation under high speeds.

This bearing handles radial loads up to 57375 lbf and spins at speeds up to 16000 RPM. The phenolic cage and extra-light preload (Class A) reduce friction, making it ideal for precision applications.

Its universal matching design allows flexible arrangements like back-to-back, face-to-face, or tandem setups. The open seal type simplifies maintenance while maintaining performance.

Suitable for high-speed machinery like spindles or CNC equipment, it operates in temperatures from -30°C to 110°C. Weighing 5.27kg, it’s robust yet precise, meeting P4A tolerance standards.
