Super Precision Angular Contact Ball Bearings 71926 ACD/P4ADFC

Super Precision Angular Contact Ball Bearings 71926 ACD/P4ADFC

The 71926 ACD/P4ADFC is a super precision angular contact ball bearing with a 130mm bore and 180mm outer diameter, crafted from durable chrome steel. It measures 130mm by 180mm by 48mm, making it a compact yet robust unit.

With a 25° contact angle and moderate preload, it handles radial loads up to 31500 lbf and spins smoothly at speeds up to 7500 RPM. The phenolic cage ensures quiet operation and long service life.

Its open design allows for easy lubrication, while the matched arrangement of two bearings (DF) provides stability under angular loads. Ideal for high-precision applications like machine tool spindles or industrial pumps.

Weighing 3.1kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for exceptional accuracy. Interchangeable with SKF bearings for convenient replacements.
