Super Precision Angular Contact Ball Bearings 71910 CE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 71910 CE/HCP4AQBCA

The 71910 CE/HCP4AQBCA is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from high-quality chrome steel. Its 15° contact angle and ceramic balls ensure smooth operation under angular loads.

Designed for extra light preload (Class A), it handles dynamic radial loads up to 7605 lbf and spins at speeds up to 46,000 RPM. The phenolic cage provides durability while keeping weight low at just 0.44kg.

This open-type bearing comes in a matched set of four (QBC arrangement), optimised for high-precision applications. Ideal for machine tools or spindle systems where accuracy and speed are critical.

It operates reliably in temperatures from -30°C to 110°C and is interchangeable with SKF equivalents. The lubricated design ensures long service life with minimal maintenance.
