SKF tapered roller bearings handle combined radial and axial loads, with a tapered roller and raceway design that distributes forces effectively. They are common in industrial machinery where both load types occur. MR Industrial Accessories supplies this line to customers across the United States, Canada, Mexico and South America.
The part number combines a basic series number with a suffix that indicates the execution. For instance, 31320 XJ2/DF, 31322 XJ2/DF and 31324 XJ2/DF belong to series 31320, 31322 and 31324, respectively, and all carry the XJ2/DF suffix. When ordering, provide the complete designation exactly as it appears on the drawing or the old bearing.
These bearings suit applications involving combined loads and moments. Typical uses include gearboxes, drive shafts, food industry machinery, mining equipment, cranes and roller systems. Their ability to operate in both directions makes them a practical choice for assemblies where space is tight.
Selection depends on radial and axial load, rotation speed and environmental conditions. Correct installation calls for careful alignment and adequate lubrication to prevent premature wear. If the bearing is mounted with an interference fit on the shaft, follow the manufacturer's recommendations for mounting and axial fixing. Clean seats and the right tools are essential.
When comparing with other brands, similar designations often differ in their suffixes. If you have a part number from another manufacturer, we can help you identify an interchangeable option. Send us the number and we will confirm a compatible alternative or quote the exact part you need.
