Super Precision Angular Contact Ball Bearings 7210 CD/P4ADT

Super Precision Angular Contact Ball Bearings 7210 CD/P4ADT

The 7210 CD/P4ADT is a super precision angular contact ball bearing with a 50mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 16380 lbf and operates smoothly at speeds up to 41000 RPM.

With a 15° contact angle and matched arrangement of two bearings, it offers excellent stability for angular loads. The phenolic cage ensures durability while keeping the weight low at 0.92kg.

Its open design allows for easy lubrication, and it performs reliably in temperatures from -30°C to 110°C. The P4A tolerance class guarantees precise operation.

Ideal for high-precision applications like machine tool spindles or industrial pumps where accuracy and speed are crucial. Interchangeable with SKF bearings for convenient replacement.
