Super Precision Angular Contact Ball Bearings 7009 ACD/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 7009 ACD/HCP4AQBCA

The 7009 ACD/HCP4AQBCA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 16380 lbf and reaches speeds of 41000 RPM, thanks to its ceramic balls and phenolic cage.

Its 25° contact angle and extra-light preload ensure smooth operation in high-precision applications. The open design allows for easy lubrication, while the P4A tolerance class guarantees consistent performance.

This set includes four matched bearings, ideal for applications requiring tight alignment, such as machine tool spindles or high-speed motors. The ceramic balls reduce friction, making it suitable for demanding environments.

Weighing 0.8kg, it operates efficiently in temperatures from -30°C to 110°C. Its compatibility with SKF bearings makes it a practical choice for replacements or upgrades.
