Super Precision Angular Contact Ball Bearings 71914 ACBGA/HCP4A

Super Precision Angular Contact Ball Bearings 71914 ACBGA/HCP4A

The 71914 ACBGA/HCP4A is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. Its 25° contact angle ensures smooth handling of combined radial and thrust loads.

With ceramic balls and a phenolic cage, it spins quietly at speeds up to 28,000 RPM while handling dynamic radial loads of 2925 lbf. The extra light preload (Class A) provides precise operation in demanding applications.

This open-design bearing comes lubricated and works in temperatures from -30°C to 110°C. It’s universally matchable for back-to-back, face-to-face, or tandem arrangements.

Ideal for high-speed machine tools or precision spindles where accuracy is crucial. Weighing 0.33kg, it meets P4A tolerance standards for exceptional performance.
