Super Precision Angular Contact Ball Bearings 7022 CD/P4ADBD

Super Precision Angular Contact Ball Bearings 7022 CD/P4ADBD

The 7022 CD/P4ADBD is a super precision angular contact ball bearing with a 110mm bore and 170mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 40050 lbf and operates smoothly at speeds up to 10000 RPM.

Its 15° contact angle and heavy preload (Class D) ensure stable performance under demanding conditions. The open design and phenolic cage make it easy to maintain while offering long service life.

This matched set of two bearings (DB arrangement) is ideal for high-precision applications like machine tool spindles or robotics. It works reliably in temperatures from -30°C to 110°C.

Weighing 3.95kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for convenient replacements.
