SKF tapered roller bearings are rolling elements that support radial and axial loads in one direction, with high load capacity. They are used in applications with combined forces, such as gearboxes, reducers, wheel axles and industrial machinery. MR Accesorios Industriales sells and distributes this line in Buenos Aires, Argentina, and advises you on choosing the right part number for your equipment.
The designation of these bearings combines a series and bore number with the suffix /QDF. For example, 33015/QDF corresponds to series 33015, 33019/QDF to 33019 and 33217/QDF to 33217. The number identifies the size and geometry of the bearing; the QDF suffix is part of the part number and does not change how the series is read. To order the replacement, simply provide the full part number as it appears on the drawing or on the part.
In Argentine industry, these bearings appear in gearboxes, reducers, wheel axles of road and agricultural equipment, machine tools and conveyors. They are also found in process pumps, mills and material handling equipment. Their ability to combine radial and axial loads makes them suitable for assemblies where the shaft works with forces in two directions, provided the arrangement and fit specified by the equipment manufacturer are respected.
To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Assembly requires precise alignment of the cones and cups, and control of the axial clearance according to the equipment specifications. Lubrication must be suitable for the working temperature and speed, and sealing the assembly prevents the entry of contaminants. If the assembly is in pairs, respect the face-to-face or back-to-back arrangement indicated in the manual.
When replacing a tapered roller bearing, equivalent part numbers from other brands are often found. Interchangeability depends on the main dimensions and the contact angle matching, so it is advisable to compare the full designations. If you have the part number from another brand or an unidentified part, send us the data and we will tell you the compatible equivalent. We can also quote the exact size you need.
