Angular Contact Ball Bearing – 3209 ATN9

The 3209 ATN9 is a double row angular contact ball bearing engineered for high-speed, high-load applications where compact design is essential. Its back-to-back configuration allows it to support significant radial and axial forces while reducing required axial space compared to two single row bearings.

With a 45 mm bore, 85 mm outside diameter, and 30.2 mm width, this bearing delivers a basic dynamic load rating of 52 kN and a static load rating of 41.5 kN. It operates reliably with a CN axial internal clearance at reference speeds up to 7,500 r/min and limiting speeds of 7,500 r/min.

Constructed from premium bearing steel with non-metallic cages, the 3209 ATN9 is suitable for industrial machinery, pumps, and gearboxes that require robust load handling, high-speed operation, and compact installation.
