Super Precision Angular Contact Ball Bearings 71912 ACE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71912 ACE/HCP4ADGA

The 71912 ACE/HCP4ADGA is a super precision angular contact ball bearing with a 60mm bore and 85mm outer diameter, crafted from chrome steel for durability. It features a 25° contact angle and ceramic balls for smooth operation.

This bearing handles radial loads up to 5648 lbf and spins at speeds up to 33,000 RPM. Its extra light preload (Class A) ensures minimal friction, while the phenolic cage offers quiet performance.

The universal matching design allows flexible arrangements (back-to-back, face-to-face, or tandem). Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing 0.32kg, it operates in temperatures from -30°C to 110°C. Comes as a matched set of two bearings for balanced performance. Compliant with P4A tolerance standards for exceptional accuracy.
