Super Precision Angular Contact Ball Bearings S7013 ACE/P4AQBCA

Super Precision Angular Contact Ball Bearings S7013 ACE/P4AQBCA

The S7013 ACE/P4AQBCA is a super precision angular contact ball bearing with a 65mm bore and 100mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 11408 lbf and operates smoothly at speeds up to 31000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and extra-light preload make it ideal for high-precision applications.

This set includes four matched bearings (QBC arrangement), offering consistent performance under angular loads. Suitable for machine tools or spindle systems where accuracy and speed are key.

Weighing 1.8kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s a reliable choice for demanding environments. Works in temperatures from -30°C to 110°C.
