Super Precision Angular Contact Ball Bearings 7213 ACD/P4ADFB

Super Precision Angular Contact Ball Bearings 7213 ACD/P4ADFB

The 7213 ACD/P4ADFB is a super precision angular contact ball bearing with a 65mm bore and 120mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and comes in a matched set of two bearings arranged back-to-back (DF).

This bearing handles radial loads up to 23400 lbf and spins smoothly at speeds up to 36000 RPM. Its phenolic cage ensures quiet operation and durability, while the open design allows for easy lubrication.

With a light preload (Class B), it offers excellent accuracy and stability, making it ideal for high-precision applications. The P4A tolerance class ensures tight performance standards are met.

Suitable for machine tools, spindles, or other high-speed equipment where precision is key. It operates reliably in temperatures from -30°C to 110°C and weighs 2.05kg for its robust size. Interchangeable with SKF bearings for easy replacement.
