Super Precision Angular Contact Ball Bearings 71922 ACD/P4ADGC

Super Precision Angular Contact Ball Bearings 71922 ACD/P4ADGC

The 71922 ACD/P4ADGC is a super precision angular contact ball bearing with a 110mm bore and 150mm outer diameter, crafted from high-grade chrome steel. Its 25° contact angle and moderate preload ensure smooth handling of combined radial and axial loads.

With a dynamic radial load capacity of 21510 lbf and speeds up to 10000 RPM, it performs reliably in demanding conditions. The phenolic cage reduces friction and wear, while the open design allows for easy lubrication.

This bearing comes in a universal matched set of two, suitable for back-to-back, face-to-face, or tandem arrangements. Ideal for high-precision applications like machine tool spindles or aerospace systems where accuracy is crucial.

Weighing 1.72kg, it operates efficiently in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for seamless replacements.
