Super Precision Angular Contact Ball Bearings 7213 CD/P4DBA

Super Precision Angular Contact Ball Bearings 7213 CD/P4DBA

The 7213 CD/P4DBA is a super precision angular contact ball bearing with a 65mm bore and 120mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched set of two bearings for balanced performance.

This bearing handles radial loads up to 24300 lbf and spins smoothly at speeds up to 32,500 RPM. Its phenolic cage ensures quiet operation and long service life, even under high-speed conditions.

The open design allows for easy lubrication, while the extra-light preload (Class A) ensures minimal friction. Ideal for precision applications like machine tool spindles or high-speed robotics.

Weighing 2.05kg, it’s robust yet manageable for its size. Compliant with P4 tolerance standards, it’s interchangeable with SKF bearings for reliable replacements. Suitable for temperatures from -30°C to 110°C.
