Super Precision Angular Contact Ball Bearings 71914 ACD/P4ADBC

Super Precision Angular Contact Ball Bearings 71914 ACD/P4ADBC

The 71914 ACD/P4ADBC is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and matched pair design (DB arrangement) ensure smooth handling of combined radial and axial loads.

This bearing supports dynamic radial loads up to 11858 lbf and reaches speeds of 28000 RPM, thanks to its phenolic cage and lubricated design. It operates reliably in temperatures from -30°C to 110°C.

The open seal allows for easy maintenance, while the P4A tolerance class guarantees exceptional precision. Ideal for high-speed applications like machine tool spindles or precision gearboxes.

Weighing 0.66kg, this matched set of two bearings offers balanced performance. It’s interchangeable with SKF models, making replacements straightforward.
