Super Precision Angular Contact Ball Bearings S71924 CD/P4AQBCC

Super Precision Angular Contact Ball Bearings S71924 CD/P4AQBCC

The S71924 CD/P4AQBCC is a super precision angular contact ball bearing with a 120mm bore and 165mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 45675 lbf and operates smoothly at speeds up to 11000 RPM.

Its sealed design keeps lubrication 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 high-precision applications.

This bearing comes in a matched set of four (QBC arrangement), ideal for spindle or machine tool use where accuracy is critical. It works well in temperatures from -30°C to 110°C and is interchangeable with SKF models.

Weighing 4.84kg, it’s robust yet precision-engineered for demanding environments. The grease lubrication simplifies maintenance, making it a practical choice for engineers.
