Super Precision Angular Contact Ball Bearings 71930 ACD/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71930 ACD/HCP4ADGA

The 71930 ACD/HCP4ADGA is a super precision angular contact ball bearing with a 150mm bore and 210mm outer diameter, designed for high-performance applications. Its 25° contact angle and ceramic balls ensure smooth operation under heavy radial loads up to 40050 lbf.

This open-type bearing comes pre-lubricated and can handle speeds up to 11000 RPM, making it suitable for demanding environments. The phenolic cage provides durability while keeping weight manageable at 4.16kg.

Its universal matching design allows flexible arrangements like back-to-back or face-to-face mounting. Ideal for machine tools or high-speed spindles where precision is key. The P4A tolerance class guarantees consistent performance in temperatures from -30°C to 110°C.

Sold as a matched set of two bearings, it’s interchangeable with SKF models for easy replacement. The chrome steel rings and ceramic balls offer a balanced combination of strength and smooth rotation.
