Super Precision Angular Contact Ball Bearings 7207 ACD/HCP4ADBA

Super Precision Angular Contact Ball Bearings 7207 ACD/HCP4ADBA

The 7207 ACD/HCP4ADBA is a super precision angular contact ball bearing with a 35mm bore and 72mm outer diameter, crafted from chrome steel for durability. It features a 25° contact angle and comes in a matched pair for balanced performance.

This bearing handles radial loads up to 11115 lbf and spins smoothly at speeds up to 56000 RPM, thanks to its ceramic balls and phenolic cage. Its extra-light preload ensures minimal friction during operation.

The open design allows for easy lubrication, while the P4A tolerance class guarantees high precision. Ideal for applications like machine tools or high-speed spindles where accuracy is crucial.

Weighing 0.48kg, it operates efficiently in temperatures from -30°C to 110°C. The matched pair arrangement (DB) provides stability under angular loads.
