Super Precision Angular Contact Ball Bearings S7009 CE/P4ADBB

Super Precision Angular Contact Ball Bearings S7009 CE/P4ADBB

The S7009 CE/P4ADBB 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 pair (DB arrangement) for balanced performance.

Designed for angular contact loads, it handles up to 4680 lbf dynamically and spins smoothly at speeds up to 41,000 RPM. The sealed design and grease lubrication make it low-maintenance and durable.

Its phenolic cage and tight tolerances (P4A class) ensure quiet, precise operation. Ideal for high-speed applications like machine tool spindles or precision equipment.

Weighing 0.5kg, this bearing operates reliably in temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings, offering a practical replacement option.
