SKF 3204 ATN9 2 Row Ball Bearing - 20 mm ID, 47 mm OD 20.6 mm Race Width

This ball bearing is a double-row angular contact design intended to support combined radial and axial loads in rotating assemblies. It features grooved steel races and bearing steel balls, with an open-end configuration suitable for installations where exposure is acceptable. The bearing is designed for high-speed operation and compatibility with equipment requiring RoHS-compliant components.

• 14000 r/min limiting speed enables high-speed operation
• 30° contact angle improves axial load capacity
• CN internal clearance reduces internal preload variability
• 20.4 kN dynamic load rating supports heavy dynamic loads
• 12.9 kN static load rating maintains positional stability under static thrust
• Non-metallic cage reduces friction and lowers noise

• Suitable for high-speed spindle assemblies
• Ideal for precision gearboxes requiring axial support
• Used with pump shafts operating at elevated speeds
• Can be used for rotary indexing tables
• Appropriate for machine-tool headstocks

The rolling elements are manufactured from bearing steel and run within steel raceways.

The non-metallic cage minimises lubrication-related metal wear and can extend re-lubrication intervals in compatible environments.

Grooved race profiles combined with a 30° contact angle distribute axial forces across both rows to manage thrust.

An open end permits direct access to the rolling elements for inspection and re-lubrication but offers less contamination protection than sealed variants.
