Angular Contact Ball Bearing – 3210 ATN9

The 3210 ATN9 is a double row angular contact ball bearing designed for high-speed and high-load applications where compactness is essential. Its back-to-back arrangement allows it to support significant radial and axial loads in both directions while reducing required axial space compared to a pair of single row angular contact bearings.

Featuring a 50 mm bore, 90 mm outside diameter, and 30.2 mm width, this bearing has a basic dynamic load rating of 51 kN and a static load rating of 42.5 kN. With a CN axial internal clearance, it operates reliably under varying load conditions and maintains performance at reference speeds up to 8,000 r/min and limiting speeds of 7,000 r/min.

Constructed from premium bearing steel with non-metallic cages, the 3210 ATN9 is ideal for industrial machinery, pumps, and gearboxes where compact design, high-speed capability, and robust load handling are critical.
