Super Precision Angular Contact Ball Bearings 71912 ACB/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71912 ACB/HCP4ADGA

The 71912 ACB/HCP4ADGA is a super precision angular contact ball bearing measuring 60mm by 85mm by 26mm, crafted from chrome steel with ceramic balls for enhanced performance. It handles radial loads up to 3578 lbf and can spin at speeds up to 33,000 RPM, making it suitable for high-speed applications.

With a 25° contact angle and universal matching, it offers flexibility in arrangements like back-to-back or face-to-face setups. The phenolic cage ensures smooth operation, while the extra light preload (Class A) reduces friction.

Ideal for precision machinery like CNC spindles or high-speed motors, this bearing operates in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees exceptional accuracy, and the lubricated design ensures long service life.

Weighing just 0.36kg, it comes in a matched set of two bearings for balanced performance. Compliant with industry standards, it’s a reliable choice for demanding engineering applications.
