TIMKEN 2TS-DM series double row tapered roller bearings are two-row units that combine two cones and a single cup, designed to carry radial and axial loads in both directions. They are used where the arrangement requires rigidity and load capacity in a confined space, such as gearboxes, road machinery axles and transmission equipment. MR Accesorios Industriales supplies them in Buenos Aires, Argentina.

The designation of these bearings starts with the letters JY followed by a five-digit number and the suffix -Q. In the examples JY12021-Q, JY13013-Q, JY14016-Q, JY20020-Q, JY23028-Q, JY24050-Q and JY28056-Q, the numeric block identifies each size within the family, while the -Q suffix indicates the execution variant of the assembly. The 2TS-DM series groups these double row assemblies, and each part number refers to a specific combination of cone, cup and internal geometry.

In Argentine industry they appear in gearboxes, reducers, agricultural machinery axles, road equipment and conveyors. They are also found in machine tool spindles and rolling mill rolls, where the double row allows load to be taken in both directions without adding components. As pre-assembled units, they simplify shaft design and reduce the number of parts to mount compared with two single bearings paired together.

To select the correct part number, start from the radial and axial loads, the rotational speed and the space available in the housing. During mounting, alignment between shaft and housing is critical: angular misalignment accelerates wear on the raceways and rollers. Lubrication must be chosen according to temperature and operating conditions, and sealing must protect the rolling zone from dust and water, especially in outdoor applications.

Between brands, double row tapered roller bearings are interchanged by mounting dimensions and load capacity, not by commercial part number. Each manufacturer builds its combinations with its own nomenclature, so equivalence is established by comparing shaft diameter, outer diameter, total width and internal arrangement. If you need to replace a TIMKEN with another brand, send us the dimensions or the part number and we will indicate the compatible alternative.

If you have the part number JY12021-Q, JY13013-Q, JY14016-Q, JY20020-Q, JY23028-Q, JY24050-Q or JY28056-Q, or any other reference from the 2TS-DM series, send it by WhatsApp to MR Accesorios Industriales and we will quote it promptly. We can also advise you on the lubrication and sealing that best suit your equipment.
