Super Precision Angular Contact Ball Bearings 7208 ACD/P4ADGC

Super Precision Angular Contact Ball Bearings 7208 ACD/P4ADGC

The 7208 ACD/P4ADGC is a super precision angular contact ball bearing with a 40mm bore and 80mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 11700 lbf and operates smoothly at speeds up to 41000 RPM.

With a 25° contact angle and universal matching design, it offers excellent stability for paired arrangements. The phenolic cage ensures durability while keeping the bearing lightweight at just 0.75kg.

Its open design allows for easy lubrication, and it performs reliably in temperatures from -30°C to 110°C. Ideal for high-precision applications like machine tool spindles or robotics where accuracy is key.

The bearing comes in a matched set of two, suitable for back-to-back, face-to-face, or tandem configurations. Interchangeable with SKF bearings, it’s a versatile choice for demanding industrial uses.
