Super Precision Angular Contact Ball Bearings 7011 CD/P4ADFC

Super Precision Angular Contact Ball Bearings 7011 CD/P4ADFC

The 7011 CD/P4ADFC is a super precision angular contact ball bearing, measuring 55mm by 90mm by 36mm. Made from chrome steel, it features a 15° contact angle and comes as a matched pair (DF arrangement) for balanced performance.

It handles radial loads up to 14332 lbf and spins smoothly at speeds up to 34000 RPM. The phenolic cage ensures quiet operation and durability, while the open design allows for easy lubrication.

With a moderate preload (Class C), this bearing offers stable performance in high-precision applications. Its P4A tolerance class ensures tight dimensional accuracy for demanding setups.

Ideal for machine tools or high-speed spindles where precision is key. The matched pair design simplifies installation in applications requiring angular contact load support. Weighing 0.76kg, it’s robust yet manageable for its size.
