Super Precision Angular Contact Ball Bearings S7013 ACE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings S7013 ACE/HCP4AQBCA

The S7013 ACE/HCP4AQBCA is a super precision angular contact ball bearing with a 65mm bore and 100mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 11408 lbf and spins smoothly at speeds up to 31000 RPM.

Its sealed design keeps grease in place, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and extra-light preload (Class A) provide excellent accuracy for high-speed applications.

This set includes four matched bearings (QBC arrangement), ideal for precision machinery like spindles or CNC tools. It operates reliably in temperatures from -30°C to 110°C.

Weighing 1.64kg, it’s robust yet balanced for its size. Compliant with P4A tolerance standards, it’s a top choice for engineers needing consistent performance.

Interchangeable with SKF bearings, it simplifies replacements. Perfect for applications demanding low friction and high rotational accuracy.
