NACHI 5209

The Double Row Angular Contact Ball Bearing with a 20° contact angle is designed to accommodate bi-directional axial, radial, and moment loads within a single bearing unit. This configuration effectively combines two single-row bearings positioned back-to-back, allowing for a more compact axial space requirement. The bearing measures 45 mm in bore diameter, 85 mm outside diameter, and has a width of 30.2 mm.

With a dynamic load capacity of 51,000 N and a static load capacity of 39,000 N, this bearing is suitable for various applications requiring reliable performance under significant loads. It operates efficiently at limiting speeds of 5,500 rpm when lubricated with grease and 7,500 rpm with oil. The open configuration allows for easy maintenance and lubrication access.
