Super Precision Angular Contact Ball Bearings S7211 ACD/HCP4ATBTC

Super Precision Angular Contact Ball Bearings S7211 ACD/HCP4ATBTC

The S7211 ACD/HCP4ATBTC is a super precision angular contact ball bearing with a 55mm bore and 100mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 25650 lbf and reaches speeds of 34000 RPM, making it suitable for high-performance applications.

Its sealed design and phenolic cage ensure smooth operation with minimal maintenance, while the moderate preload (Class C) enhances stability. The bearing operates efficiently in temperatures from -30°C to 110°C.

This set includes three matched bearings arranged in a TBT configuration, ideal for applications requiring high precision and load distribution. Commonly used in machine tools or spindle systems where accuracy is crucial.

Weighing 1.55kg, it’s robust yet manageable for its size. The P4A tolerance class guarantees exceptional precision, and it’s interchangeable with SKF bearings for easy replacement.
