Super Precision Angular Contact Ball Bearings S7008 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings S7008 ACD/P4ADGA

The S7008 ACD/P4ADGA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 5850 lbf and spins smoothly at speeds up to 41,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 25° contact angle makes it ideal for handling combined radial and axial loads.

This bearing comes in a matched set of two, allowing universal mounting in back-to-back, face-to-face, or tandem configurations. Perfect for high-speed applications like machine tool spindles or precision equipment.

Weighing just 0.39kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance class for exceptional precision.
