Super Precision Angular Contact Ball Bearings S71911 CB/HCP4ADGA

Super Precision Angular Contact Ball Bearings S71911 CB/HCP4ADGA

The S71911 CB/HCP4ADGA is a super precision angular contact ball bearing with a 55mm bore and 80mm outer diameter, designed for high-speed applications. It features a 15° contact angle and sealed design, offering smooth operation with ceramic balls and a phenolic cage.

This bearing handles radial loads up to 3668 lbf and spins at speeds up to 34,000 RPM, making it suitable for demanding tasks. Its extra-light preload ensures minimal friction, while the universal matching allows flexible arrangement in back-to-back, face-to-face, or tandem setups.

The chrome steel rings and ceramic balls provide durability, and the grease lubrication simplifies maintenance. Ideal for precision machinery like spindles or CNC equipment, it operates in temperatures from -30°C to 110°C.

Weighing 0.36kg, this matched set includes two bearings for balanced performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF models for easy replacement.
