Super Precision Angular Contact Ball Bearings S7009 CD/P4ADBA

Super Precision Angular Contact Ball Bearings S7009 CD/P4ADBA

The S7009 CD/P4ADBA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes sealed for protection, with two bearings in a back-to-back arrangement.

This model handles radial loads up to 10530 lbf and spins smoothly at speeds up to 46000 RPM, thanks to its phenolic cage and grease lubrication. Its extra-light preload ensures minimal friction during operation.

The sealed design keeps contaminants out, while the P4A tolerance class guarantees high precision. Ideal for applications like machine tool spindles or high-speed robotics where accuracy is key.

Weighing 0.47kg, this matched set offers reliable performance in temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings for easy replacements.
