Super Precision Angular Contact Ball Bearings 7009 ACEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 7009 ACEGA/HCP4AL

The 7009 ACEGA/HCP4AL is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 2722 lbf.

With a maximum speed of 46,000 RPM, this bearing is designed for high-performance applications. The phenolic cage adds stability, while the extra-light preload reduces friction for efficient spinning.

Its open design allows easy lubrication, and it operates reliably in temperatures from -30°C to 110°C. The P4A tolerance class guarantees precision, making it ideal for machine tools or high-speed spindles.

Weighing just 0.22kg, it’s lightweight yet robust. This bearing can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use. Interchangeable with SKF models, it’s a practical choice for replacements.
