Super Precision Angular Contact Ball Bearings 7011 CD/HCP4ADGA

Super Precision Angular Contact Ball Bearings 7011 CD/HCP4ADGA

The 7011 CD/HCP4ADGA is a super precision angular contact ball bearing, measuring 55mm by 90mm by 36mm. Made from chrome steel with ceramic balls, it offers high performance and durability. Its 15° contact angle and universal matching design provide flexibility in arrangement.

This bearing handles dynamic radial loads up to 14332 lbf and spins smoothly at speeds up to 34000 RPM. The phenolic cage ensures stability, while the extra light preload (Class A) minimises friction for efficient operation. It works well in temperatures from -30°C to 110°C.

The open design allows easy lubrication, and the P4A tolerance class ensures precise performance. Ideal for high-speed applications like machine tool spindles or precision instruments. The matched set of two bearings supports various configurations (back-to-back, face-to-face, or tandem).

Weighing 0.63kg, it’s a robust yet lightweight choice for demanding setups. Compliant with industry standards, it’s interchangeable with SKF bearings for easy replacements.
