Super Precision Angular Contact Ball Bearings S71922 ACDGC/P4A

Super Precision Angular Contact Ball Bearings S71922 ACDGC/P4A

The S71922 ACDGC/P4A is a super precision angular contact ball bearing with a 110mm bore and 150mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 13162 lbf and operates smoothly at speeds up to 10000 RPM.

Its sealed design keeps lubrication in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The bearing works reliably in temperatures from -30°C to 110°C.

With a 25° contact angle and moderate preload, it’s ideal for high-precision applications like machine tool spindles or robotics. The P4A tolerance class guarantees exceptional accuracy.

Weighing 0.88kg, it’s part of a matched set for universal mounting options (back-to-back, face-to-face, or tandem). Compliant with industry standards, it’s interchangeable with SKF bearings for easy replacement.
