Super Precision Angular Contact Ball Bearings S7212 ACD/P4ADBA

Super Precision Angular Contact Ball Bearings S7212 ACD/P4ADBA

The S7212 ACD/P4ADBA is a super precision angular contact ball bearing with a 60mm bore and 110mm outer diameter, designed for high-speed applications. Its 25° contact angle and sealed design ensure smooth operation under radial loads up to 19890 lbf.

Made from chrome steel with a phenolic cage, it handles speeds up to 32,500 RPM and temperatures from -30°C to 110°C. The extra light preload (Class A) reduces friction, making it energy-efficient.

This matched set of two bearings (DB arrangement) offers stable performance in demanding conditions. Ideal for machine tools or spindle drives where precision and reliability are key.

Weighing 1.65kg, it’s compatible with SKF bearings for easy replacement. The grease lubrication simplifies maintenance.
