Timken double row tapered roller bearings are assemblies that combine two rows of tapered rollers in a single unit, allowing them to support radial and axial loads in both directions. They are used in applications requiring high load capacity and rigidity, such as gearboxes, drive shafts and mining equipment. MR Accesorios Industriales supplies this line with the backing of more than 80 years in the industry.

The designation of these Timken bearings is organized by series. The TDO series corresponds to double row assemblies with two cones and a common cup, and it is the one that groups examples such as HM120848, HM227519 or HM321245. The alphabetic prefixes (HM, HH, etc.) identify families of dimensions and capacities, while the following numbers define the size. The 2TS-IM and 2TS-DM series are double row variants with specific mounting configurations. To correctly interpret each code, it is best to consult with the technical team at MR Accesorios Industriales.

These bearings are used in industries that demand strength and durability. In Argentina, we find them in mill gearboxes, presses, cranes, road and railway equipment, and in the oil industry. They are also used in support rollers for kilns and in construction machinery. Their double row design makes them suitable for supporting high radial loads and axial loads in both directions, which reduces the need for additional bearings.

To select the right bearing, take into account the radial and axial load it must support, the rotation speed and environmental conditions. Sealing is key: if there is dust or moisture, it is advisable to choose configurations with seals. Lubrication must be as specified by the manufacturer, and mounting requires precise alignment to avoid undue stresses. Incorrect adjustment can reduce bearing life. If you need advice, the MR team can help you choose the best option.

Regarding equivalences, Timken bearings can be interchanged with those of other recognized brands, but it is essential to verify dimensions and load capacities. Not all codes are directly interchangeable; sometimes the mounting must be adjusted. Therefore, it is always advisable to consult a specialist before replacing one bearing with another of a different brand. MR Accesorios Industriales supplies the Timken line and can guide you on the best alternative for your equipment.
