Super Precision Angular Contact Ball Bearings S71922 ACE/HCP4ADGA

Super Precision Angular Contact Ball Bearings S71922 ACE/HCP4ADGA

The S71922 ACE/HCP4ADGA is a super precision angular contact ball bearing with a 110mm bore and 150mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This sealed bearing handles radial loads up to 14040 lbf and reaches speeds of 10000 RPM, thanks to its phenolic cage and grease lubrication. The extra-light preload (Class A) minimises friction for high-precision applications.

Designed for universal matching, it comes as a set of two bearings for versatile arrangements (back-to-back, face-to-face, or tandem). Ideal for machine tools or high-speed spindles where precision and reliability matter.

Weighing 1.43kg, it operates in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
