The double row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single mounting, designed to support 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 supplies the TIMKEN brand in Buenos Aires, Argentina, and advises you on choosing the correct part number for your application.

The designation of this series is read by the prefix HM followed by a base number and the suffix D, which indicates double row. For example, HM231116D, HM237542D and HM252311D share the structure: the letters identify the dimension family and the number the combination of diameter and width. The suffix D indicates that it is a two-row bearing, unlike single row bearings. Within the TDO, TDI and TNA series, each variant defines the arrangement of the cones and cups.

These bearings are used in industries such as metallurgy, cement, mining and heavy machinery manufacturing. In Argentina, they are commonly found in speed reducers, rolling mill rolls, mill shafts and material handling equipment. Their ability to support combined loads and moments makes them suitable for mountings where alignment is critical. They are also used in overhead cranes and power transmission systems that require high rigidity and durability.

To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. Sealing is key: if there is contamination, choose variants with integrated seals. Lubrication must be suitable for the working temperature, and mounting requires precise alignment to avoid additional stresses. Internal clearance is adjusted according to the type of application, and it is essential to follow the manufacturer's recommendations for mounting and commissioning.

Regarding equivalences and interchangeability, double row tapered roller bearings from different brands may differ in dimensions and capacities. Always verify the critical dimensions: bore, outside diameter and overall width. The TIMKEN TDO series has equivalents in other brands, but there is no universal correspondence. Therefore, when requesting a quote, it is important that you provide the complete part number or the exact dimensions so we can offer you the compatible alternative.
