Super Precision Angular Contact Ball Bearings S7022 CD/P4AQBCC

Super Precision Angular Contact Ball Bearings S7022 CD/P4AQBCC

The S7022 CD/P4AQBCC is a super precision angular contact ball bearing with a 110mm bore and 170mm outer diameter, crafted from high-grade chrome steel. It handles radial loads up to 65475 lbf and operates smoothly at speeds up to 16000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 15° contact angle and moderate preload (Class C) provide excellent stability for precision applications.

This bearing comes in a matched set of four (QBC arrangement), ideal for high-accuracy machinery like CNC spindles or grinding equipment. It works reliably in temperatures from -30°C to 110°C.

Weighing 7.98kg, it’s a robust choice for industrial use. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
