Super Precision Angular Contact Ball Bearings 7009 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings 7009 ACD/P4ADGA

The 7009 ACD/P4ADGA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 9945 lbf and operates smoothly at speeds up to 41,000 RPM.

With a 25° contact angle and universal matching design, it offers flexibility for back-to-back, face-to-face, or tandem arrangements. The phenolic cage ensures durability and reduces friction during high-speed rotations.

This bearing is preloaded for extra light performance, making it ideal for precision applications like machine tool spindles or high-speed robotics. It works reliably in temperatures from -30°C to 110°C.

Weighing 0.47kg, it comes as a matched set of two bearings for balanced performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF models for easy replacements.
