Super Precision Angular Contact Ball Bearings S7009 CE/P4ADBA

Super Precision Angular Contact Ball Bearings S7009 CE/P4ADBA

The S7009 CE/P4ADBA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from durable chrome steel. Its compact 32mm width and sealed design make it suitable for high-speed applications, reaching up to 41,000 RPM.

With a 15° contact angle and matched arrangement of two bearings, it handles both radial and angular loads effectively. The phenolic cage ensures smooth operation, while the extra-light preload enhances precision.

Grease-lubricated and sealed for protection, it performs reliably in temperatures from -30°C to 110°C. Ideal for machine tools or spindle drives where accuracy and speed are key.

Weighing 0.5kg, this bearing is interchangeable with SKF models, offering a practical replacement option. Compliant with P4A tolerance standards for consistent performance.
