Super Precision Angular Contact Ball Bearings 71922 ACEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71922 ACEGA/HCP4AL

The 71922 ACEGA/HCP4AL 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 radial loads up to 8482 lbf.

This open-design bearing spins efficiently at speeds up to 10,000 RPM and works in temperatures from -30°C to 110°C. The phenolic cage adds stability, while the extra-light preload reduces friction for high-precision tasks.

Ideal for machine tools or high-speed spindles, it’s part of a matched set of four bearings for versatile arrangements. Weighing 0.7kg, it meets P4A tolerance standards for reliable performance.

Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades in demanding applications. The lubricated design ensures easy maintenance and long service life.
