The double row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single unit, designed to support combined radial and axial loads in both directions. It is used in applications that require high load capacity and rigidity, such as gearboxes, machine tool spindles and mining equipment. NTN is a leading brand in bearings, and MR Accesorios Industriales will quote it for you on WhatsApp.

The designation of these bearings follows a scheme where letters and numbers indicate construction characteristics. For example, in T-E-HM252349D/HM252310/HM252310D, the T-E prefix indicates a double row design with assembled cup and cone; HM identifies the dimension series; the numbers HM252349D, HM252310 and HM252310D correspond to the cone, the cup and the auxiliary cone respectively. The D suffix indicates an internal modification, such as a lubrication hole or a special treatment. Knowing this nomenclature helps identify the correct part.

These bearings are used in Argentine industries such as metallurgical, cement, mining and machine tool. They are present in speed reducers, main spindles of lathes and milling machines, backup rollers in rolling mills and material handling equipment. Their ability to support combined loads and their rigidity make them suitable for assemblies where precision and durability are required.

To select the right bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Installation must guarantee precise alignment and adequate internal clearance, since an incorrect fit can reduce service life. Lubrication must be the one recommended by the manufacturer, and sealing must protect against contaminants. In assemblies with two bearings, it is common to perform an axial adjustment to achieve the desired clearance.

NTN double row tapered roller bearings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as Timken or SKF, as long as the dimensions and capacities are verified. In general, the HM and similar series are standard, but it is essential to confirm the exact equivalence. If you have doubts, contact us with the part number and we will advise you.
