Super Precision Angular Contact Ball Bearings S7012 ACE/HCP4ADBA

Super Precision Angular Contact Ball Bearings S7012 ACE/HCP4ADBA

The S7012 ACE/HCP4ADBA is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This sealed unit comes pre-greased and can handle speeds up to 31,000 RPM, making it suitable for high-performance applications. The phenolic cage provides stability while keeping weight low at just 0.8kg per bearing.

Designed as a matched pair (DB arrangement), these bearings offer extra light preload for precise motion control. They perform reliably in temperatures from -30°C to 110°C.

Ideal for machine tool spindles or high-speed robotics where accuracy is crucial. The P4A tolerance class guarantees consistent performance, while being interchangeable with SKF equivalents for easy replacement.
