Super Precision Angular Contact Ball Bearings S7012 ACD/P4AQBCD

Super Precision Angular Contact Ball Bearings S7012 ACD/P4AQBCD

The S7012 ACD/P4AQBCD is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel. It handles heavy radial loads up to 22725 lbf and spins smoothly at speeds up to 32,500 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 25° contact angle and heavy preload (Class D) provide excellent stability for high-precision applications.

This set includes four matched bearings (QBC arrangement), ideal for spindle or machine tool use. It performs reliably in temperatures from -30°C to 110°C.

Weighing 1.63kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement. Perfect for demanding industrial or aerospace applications where precision matters.
