Super Precision Angular Contact Ball Bearings 71914 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings 71914 ACEGA/HCP4A

The 71914 ACEGA/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 efficiently handles combined radial and thrust loads, while the ceramic balls reduce friction for smoother operation.

This open-design bearing supports speeds up to 31,000 RPM and operates in temperatures from -30°C to 110°C. The phenolic cage ensures stability, and the extra-light preload (Class A) minimises vibration during high-speed use.

Ideal for precision applications like machine tool spindles or high-performance motors, it’s interchangeable with SKF bearings. Weighing 0.27kg, it’s lightweight yet robust, with a P4A tolerance class for exceptional accuracy.

The bearing can be paired in back-to-back, face-to-face, or tandem arrangements for versatile setups. Compliant with industry standards, it’s a reliable choice for demanding engineering environments.
