Super Precision Angular Contact Ball Bearings S71916 ACD/P4ADBB

Super Precision Angular Contact Ball Bearings S71916 ACD/P4ADBB

The S71916 ACD/P4ADBB is a super precision angular contact ball bearing with an 80mm bore and 110mm outer diameter, crafted from durable chrome steel. Its compact 32mm width makes it suitable for tight spaces, while the 25° contact angle ensures efficient load handling.

This sealed bearing set (two matched units) handles radial loads up to 12578 lbf and spins smoothly at 28,000 RPM. The phenolic cage and grease lubrication provide quiet, long-lasting performance in temperatures from -30°C to 110°C.

The light preload (Class B) reduces vibration, ideal for high-precision applications like machine tool spindles or medical equipment. Its P4A tolerance class guarantees consistent accuracy under demanding conditions.

Weighing 0.76kg, this SKF-interchangeable set balances strength and precision. The sealed design keeps contaminants out, reducing maintenance needs in dusty or humid environments.
