The TIMKEN double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on the same shaft, designed to support radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, mining equipment and heavy machinery. MR Accesorios Industriales supplies this line backed by more than 80 years in the industry.

The designation of this series is identified by the suffix TD, which indicates double row. Examples such as 688TD, 19146TD, 71457TD and 93826TD show that the base number identifies the size and geometry of the assembly, while the final letters indicate the two-row configuration. The TDIT series is the TIMKEN catalogue reference for this family. To select the correct part number, take into account the shaft diameter, the loads and the mounting type.

These bearings are used in industries such as mining, cement, steel and in the manufacture of agricultural and road machinery in Argentina. They are found in gearboxes, support rollers, overhead cranes and crushing equipment. Their ability to support combined loads and moments makes them suitable for mountings requiring high rigidity and rotational precision.

For a correct selection, consider the sealing: these bearings can be mounted with radial shaft seals or seals depending on the environment. Lubrication must be adequate for the operating speed and temperature. Alignment between the shaft and the housing is critical to avoid additional stresses. Internal clearance must be verified according to the mounting. In double row mountings, preload adjustment is commonly required to ensure the rigidity of the assembly.

Regarding equivalences, double row tapered roller bearings from different brands can be interchanged if dimensions and load capacity match. It is important to verify tolerances and internal design, as they may vary between manufacturers. To find the right replacement, it is advisable to compare the main dimensions and operating conditions. MR Accesorios Industriales advises you to choose the compatible option.
