Super Precision Angular Contact Ball Bearings S71913 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings S71913 ACD/P4ADGA

The S71913 ACD/P4ADGA is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and sealed design ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 7178 lbf and spins at speeds up to 31,000 RPM, thanks to its phenolic cage and grease lubrication. It operates efficiently in temperatures from -30°C to 110°C.

Designed for universal matching, it comes in a set of two, suitable for back-to-back, face-to-face, or tandem arrangements. Its extra-light preload (Class A) ensures minimal friction and precise performance.

Ideal for high-precision applications like machine tool spindles or robotics, where accuracy and durability are key. Weighing 0.42kg, it’s a robust yet lightweight choice for demanding setups.
