Super Precision Angular Contact Ball Bearings 71914 CD/P4ADBC

Super Precision Angular Contact Ball Bearings 71914 CD/P4ADBC

The 71914 CD/P4ADBC is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. It measures 32mm in width and comes as a matched pair for balanced performance.

This bearing handles radial loads up to 12578 lbf and spins smoothly at speeds up to 24000 RPM, thanks to its 15° contact angle and phenolic cage. It operates efficiently in temperatures from -30°C to 110°C.

Its open design allows easy lubrication, while the moderate preload ensures stable operation under angular loads. The P4A tolerance class guarantees high precision for demanding applications.

Ideal for machine tools or high-speed spindles where accuracy is crucial. Weighing 0.66kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings for convenient replacements.
