Super Precision Angular Contact Ball Bearings 7022 ACD/HCP4ADBC

Super Precision Angular Contact Ball Bearings 7022 ACD/HCP4ADBC

The 7022 ACD/HCP4ADBC is a super precision angular contact ball bearing with a 110mm bore and 170mm outer diameter, designed for high-performance applications. Made from chrome steel and ceramic balls, it offers excellent durability and smooth operation.

With a 25° contact angle and moderate preload, it handles both radial and axial loads efficiently, up to 37800 lbf dynamically. Its phenolic cage ensures stability at speeds up to 10000 RPM, making it suitable for demanding environments.

The open design allows easy lubrication, while the matched pair arrangement (DB configuration) enhances load distribution. Ideal for machine tools or high-speed spindles where precision is key.

Weighing 3.27kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for consistent performance.
