Super Precision Angular Contact Ball Bearings S7211 ACDGC/P4A

Super Precision Angular Contact Ball Bearings S7211 ACDGC/P4A

The S7211 ACDGC/P4A is a super precision angular contact ball bearing with a 55mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and sealed design ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 11858 lbf and reaches speeds of 34000 RPM, making it suitable for high-performance applications. The phenolic cage adds durability while keeping weight low at just 0.62kg.

Its P4A tolerance class guarantees precise performance, and the grease lubrication simplifies maintenance. The bearing operates in temperatures from -30°C to 110°C.

Ideal for machine tools or spindle applications, it can be paired in back-to-back, face-to-face, or tandem arrangements. Interchangeable with SKF bearings, it offers a reliable solution for precision engineering needs.
