Super Precision Angular Contact Ball Bearings S7209 CDGA/P4A

Super Precision Angular Contact Ball Bearings S7209 CDGA/P4A

The S7209 CDGA/P4A is a super precision angular contact ball bearing with a 45mm bore and 85mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 9518 lbf and operates smoothly at high speeds up to 46,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 15° contact angle provides excellent stability for angular loads.

This bearing is ideal for precision applications like machine tool spindles or high-speed motors. It comes pre-greased and works in temperatures from -30°C to 110°C.

Weighing 0.42kg, it’s robust yet manageable. The P4A tolerance class ensures top-tier accuracy, and it can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use.
