Super Precision Angular Contact Ball Bearings 7209 ACD/P4ADFC

Super Precision Angular Contact Ball Bearings 7209 ACD/P4ADFC

The 7209 ACD/P4ADFC is a super precision angular contact ball bearing with a 45mm bore and 85mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently handles combined radial and axial loads, with a dynamic radial load capacity of 14918 lbf.

Designed for high-speed applications, it spins smoothly up to 41000 RPM and operates in temperatures from -30°C to 110°C. The phenolic cage ensures quiet performance and reduces friction, while the open design allows easy lubrication.

This matched set of two bearings (arranged face-to-face) offers moderate preload for stability in demanding setups. Ideal for precision machinery like spindles or CNC equipment where accuracy and speed are crucial.

Weighing 0.82kg, it’s robust yet manageable for its size. Compliant with P4A tolerance class, it’s interchangeable with SKF bearings for reliable replacements.
