Super Precision Angular Contact Ball Bearings 7009 CD/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 7009 CD/HCP4AQBCA

The 7009 CD/HCP4AQBCA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched set of four bearings for balanced performance.

This bearing handles radial loads up to 17122 lbf and reaches speeds of 46000 RPM, thanks to its ceramic balls and phenolic cage. The extra-light preload ensures smooth operation with minimal friction.

Its open design allows for easy lubrication, while the P4A tolerance class guarantees high precision. Ideal for applications like machine tool spindles or high-speed robotics where accuracy is key.

Weighing 0.8kg, it operates reliably in temperatures from -30°C to 110°C. The interchangeable design with SKF bearings makes it a practical choice for replacements or upgrades.
