Super Precision Angular Contact Ball Bearings 71922 ACE/HCP4ALDT

Super Precision Angular Contact Ball Bearings 71922 ACE/HCP4ALDT

The 71922 ACE/HCP4ALDT is a super precision angular contact ball bearing with a 110mm bore and 150mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 14040 lbf and operates smoothly at speeds up to 10000 RPM.

Its 25° contact angle and ceramic balls reduce friction, while the phenolic cage ensures quiet performance. The matched pair design (DT arrangement) offers stability for high-precision applications.

This bearing is lubricated for easy maintenance and works in temperatures from -30°C to 110°C. Ideal for machine tools or spindle drives where accuracy and speed are crucial.

Weighing 1.4kg, it meets P4A tolerance standards for reliable performance. Interchangeable with SKF bearings, making replacements straightforward.
