Super Precision Angular Contact Ball Bearings S71924 CE/P4A

Super Precision Angular Contact Ball Bearings S71924 CE/P4A

The S71924 CE/P4A is a super precision angular contact ball bearing with a 120mm bore and 165mm outer diameter, crafted from high-grade chrome steel. Its 15° contact angle efficiently manages both radial and axial loads, making it versatile for demanding setups.

This sealed unit comes pre-lubricated, reducing maintenance needs while supporting speeds up to 11,200 RPM. With a phenolic cage and P4 tolerance, it ensures smooth, quiet operation even under heavy loads (up to 10,688 lbf dynamically).

The bearing’s compact 22mm width and 1.14kg weight suit space-conscious applications. It performs reliably in temperatures from -30°C to 110°C.

Ideal for precision machinery like spindles or CNC tools, it’s interchangeable with SKF equivalents for easy replacement. The sealed design keeps contaminants out, extending service life.
