SKF 2 Row Angular Contact Ball Bearing 45 mm ID 85 mm OD 30.2 mm Race Width 3209 ATN9

SKF 3209 ATN9 is a high-quality 2 Row Angular Contact Ball Bearing with a 45 mm inside diameter, 85 mm outside diameter, and 30.2 mm race width, designed for industrial applications requiring combined radial and axial load handling. It features a durable steel ball construction with a non-metallic cage to reduce friction and mass. The open end design facilitates maintenance operations such as inspection and re-lubrication.

The bearing has a 30° contact angle enabling matched axial load support, suitable for demanding environments including compact gearboxes, electric motors, spindle systems requiring high rpm, rotary indexing mechanisms, and pump shaft assemblies under axial load. The parallel bore type fits cylindrical shafts with interference or transition fits, ensuring secure installation.

With a static load rating of 41.5 kN and a dynamic load rating of 52 kN, this bearing is engineered to sustain heavy stationary and high-cycle loads. It supports a limiting speed of up to 7,500 rpm, making it suitable for high-speed rotation applications. The CN internal clearance permits thermal expansion, enhancing reliability in variable temperature conditions.

Double row angular contact design provides combined radial and axial load handling. 30° contact angle offers matched axial load capacity. Non-metallic cage reduces mass and friction. Steel balls deliver hardness and fatigue resistance.
