Super Precision Angular Contact Ball Bearings S7008 ACD/P4ADBA

Super Precision Angular Contact Ball Bearings S7008 ACD/P4ADBA

The S7008 ACD/P4ADBA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and sealed design ensure smooth operation under angular loads.

This matched set of two bearings (DB arrangement) handles radial loads up to 5850 lbf and spins at impressive speeds up to 41,000 RPM. The phenolic cage and grease lubrication provide quiet, long-lasting performance.

With extra light preload (Class A) and P4A tolerance, it offers exceptional accuracy for demanding applications. Ideal for high-speed spindles or precision machinery where minimal vibration is crucial.

Weighing 0.39kg, this compact unit operates reliably in temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings, making maintenance straightforward.
