Super Precision Angular Contact Ball Bearings 71914 CD/HCP4ATGA

Super Precision Angular Contact Ball Bearings 71914 CD/HCP4ATGA

The 71914 CD/HCP4ATGA is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. Its 15° contact angle and ceramic balls ensure smooth operation under high speeds.

This bearing handles radial loads up to 16672 lbf and spins at speeds up to 24000 RPM. The phenolic cage and extra-light preload (Class A) reduce friction for efficient performance.

Its open design allows easy lubrication, and it works in temperatures from -30°C to 110°C. The universal matching feature lets you arrange bearings back-to-back, face-to-face, or tandem.

Ideal for high-precision applications like machine tool spindles or aerospace components. Weighing 0.85kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings for easy replacements.
