Super Precision Angular Contact Ball Bearings 7009 ACEGA/P4A

Super Precision Angular Contact Ball Bearings 7009 ACEGA/P4A

The 7009 ACEGA/P4A 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 25° contact angle and is designed for angular contact loads, handling up to 2722 lbf dynamically.

This bearing spins smoothly at speeds up to 46,000 RPM, thanks to its phenolic cage and lubricated design. Its extra-light preload (Class A) ensures minimal friction and precise operation.

With a temperature range of -30°C to 110°C, it’s suitable for demanding environments. The P4A tolerance class guarantees exceptional accuracy for high-performance applications.

Ideal for machine tools or spindle drives, it’s interchangeable with SKF bearings. Weighing just 0.24kg, it’s lightweight yet robust. Universal matching options (back-to-back, face-to-face, or tandem) offer flexibility in assembly.
