Super Precision Angular Contact Ball Bearings S71910 ACD/P4ADGC

Super Precision Angular Contact Ball Bearings S71910 ACD/P4ADGC

The S71910 ACD/P4ADGC is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 4680 lbf and spins smoothly at speeds up to 34,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle and universal matching allow flexible arrangements like back-to-back or face-to-face.

This bearing is ideal for high-precision applications like machine tool spindles or robotics, where accuracy and speed matter. It operates reliably in temperatures from -30°C to 110°C.

Weighing just 0.27kg, it’s lightweight yet robust. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
