Super Precision Angular Contact Ball Bearings 71911 ACEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71911 ACEGA/HCP4AL

The 71911 ACEGA/HCP4AL is a super precision angular contact ball bearing with a 55mm bore and 80mm outer diameter, designed for high-speed applications. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 3330 lbf.

This open-type bearing comes pre-lubricated and can handle speeds up to 39,000 RPM, making it suitable for demanding environments. The phenolic cage adds durability while keeping weight low at just 0.14kg.

With a P4A tolerance class, it offers exceptional accuracy for precision machinery. The bearing works in temperatures from -30°C to 110°C and can be paired in back-to-back or face-to-face arrangements.

Ideal for spindle drives or high-precision tools where speed and accuracy matter. Interchangeable with SKF bearings for easy replacement.
