Super Precision Angular Contact Ball Bearings 7222 ACD/P4ADGB

Super Precision Angular Contact Ball Bearings 7222 ACD/P4ADGB

The 7222 ACD/P4ADGB is a super precision angular contact ball bearing with a 110mm bore and 200mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 62100 lbf and operates smoothly at speeds up to 16250 RPM.

With a 25° contact angle and universal matching design, it offers excellent stability for paired arrangements like back-to-back or face-to-face. The phenolic cage ensures durability and reduces friction during high-speed rotations.

This bearing is preloaded for light performance (Class B) and works in temperatures from -30°C to 110°C. Ideal for precision machinery, spindles, or applications requiring tight tolerances (P4A class).

Weighing 9.26kg, it comes as a matched set of two bearings, interchangeable with SKF models. Its open design allows easy lubrication for long service life.
