Super Precision Angular Contact Ball Bearings S71919 CDGA/P4A

Super Precision Angular Contact Ball Bearings S71919 CDGA/P4A

The S71919 CDGA/P4A is a super precision angular contact ball bearing with a 95mm bore and 130mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 11115 lbf and operates smoothly at speeds up to 21000 RPM.

Its sealed design keeps grease 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 15° contact angle and extra light preload, it’s ideal for high-precision applications like machine tool spindles or high-speed motors. The P4A tolerance class guarantees exceptional accuracy.

Weighing just 0.6kg, it’s part of a matched set of four bearings, suitable for universal matching in back-to-back, face-to-face, or tandem arrangements. Interchangeable with SKF models for easy replacements.
