Super Precision Angular Contact Ball Bearings 7022 ACE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 7022 ACE/HCP4ADGA

The 7022 ACE/HCP4ADGA is a super precision angular contact ball bearing with a 110mm bore and 170mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 16380 lbf and operates smoothly at speeds up to 16250 RPM.

With a 25° contact angle and universal matching design, it offers flexibility for back-to-back, face-to-face, or tandem arrangements. The phenolic cage ensures quiet performance and longevity, even in demanding conditions.

This bearing is lubricated for easy maintenance and works in temperatures from -30°C to 110°C. Its extra light preload (Class A) makes it ideal for high-precision applications like machine tools or spindle drives.

Weighing 3.86kg, it comes as a matched set of two bearings, interchangeable with SKF models. Perfect for setups requiring tight tolerances (P4A) and reliable angular contact performance.
