The TIMKEN TDI series tapered roller bearing is a double row assembly designed to withstand combined radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, drive shafts and industrial equipment. MR Accesorios Industriales carries this line.
The TDI series designation is complemented by the part number of each assembly. In the example 389DE, the letters DE identify the double row configuration with matched cone and cup. This nomenclature allows quick recognition of the bearing type and its internal arrangement, making selection easier compared with other tapered roller variants.
In Argentine industry, TIMKEN TDI series bearings are used in speed reducers, mills, presses, cranes and mining equipment. Their ability to withstand combined loads makes them suitable for drive shafts and support rollers in steel, cement and oilseed plants, where continuous service demands are high.
To select correctly, take into account radial and axial load, rotation speed and environmental conditions. Mounting requires precise alignment and proper adjustment of internal clearance, since tapered rollers work with a defined preload. Lubrication must be as specified by the manufacturer and sealing, if applicable, must protect against contaminants.
Double row tapered roller bearings can be interchanged between brands if the main dimensions and load capacity match. However, each manufacturer defines its own tolerances and clearances, so it is advisable to verify the equivalent with a specialist before replacing. MR Accesorios Industriales advises you to find the compatible alternative.
