Super Precision Angular Contact Ball Bearings 71922 ACDGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71922 ACDGA/HCP4AL

The 71922 ACDGA/HCP4AL is a super precision angular contact ball bearing with a 110mm bore and 150mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently manages both radial and axial loads, while the ceramic balls reduce friction for smoother operation.

This open-design bearing comes pre-lubricated and can handle speeds up to 10,000 RPM, making it suitable for high-performance applications. The phenolic cage ensures stability, even under dynamic radial loads of 13162 lbf.

With a tolerance class of P4A, it offers exceptional accuracy for precision machinery. Ideal for spindle assemblies or high-speed tooling, it operates reliably between -30°C and 110°C.

Weighing 0.73kg, it’s part of a universal matching set, allowing flexible arrangements like back-to-back or tandem configurations. Interchangeable with SKF bearings, it’s a versatile choice for demanding setups.
