Super Precision Angular Contact Ball Bearings S7209 CD/P4ADBA

Super Precision Angular Contact Ball Bearings S7209 CD/P4ADBA

The S7209 CD/P4ADBA is a super precision angular contact ball bearing with a 45mm bore and 85mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched set of two bearings for balanced performance.

This model handles radial loads up to 15795 lbf and operates smoothly at speeds up to 46000 RPM. Its phenolic cage and grease lubrication ensure quiet, long-lasting performance even in demanding conditions.

The sealed design keeps contaminants out, while the extra-light preload (Class A) minimises friction. Ideal for high-precision applications like machine tool spindles or robotics, where accuracy is key.

Weighing 0.84kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, this bearing offers reliable interchangeability with SKF equivalents. Works in temperatures from -30°C to 110°C.
