The double row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single mounting, which allows it to support radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, machine tool shafts and mining equipment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, with more than 80 years of experience in the industry.

The designation of these NTN bearings is made up of several codes that identify each component of the assembly. For example, in E-LM247748D/LM247710/LM247710DA, the prefix E- indicates a special execution, followed by LM247748D which corresponds to the double row inner cone, LM247710 to the single outer ring and LM247710DA to the double outer ring. The series is recognized by the letters LM and the suffixes D and DA that indicate double row configurations. The examples E-LM772749D/LM772710/LM772710DA follow the same logic.

These bearings are used in industries such as metallurgy, cement, mining and heavy machinery manufacturing. In Argentina, they are commonly found in speed reducers, machine tool spindles, overhead cranes and earthmoving equipment. Their double row design makes them suitable for supporting combined loads and tilting moments, so they are also used in support rollers and rotary tables.

To select the right bearing, take into account the radial and axial load capacity it must support, the rotation speed and the environmental conditions. Mounting requires precise alignment and adequate lubrication, generally with grease or oil, depending on the application. Sealing is essential to prevent contamination by dust or particles, so it is recommended to evaluate the use of additional seals or bearings with integrated seals.

As for equivalents, double row tapered roller bearings from other brands can be interchanged if the main dimensions and the arrangement of the rows match. It is important to verify the complete part number and the tolerances, since small differences can affect operation. MR Accesorios Industriales can advise you on interchangeability and source the exact reference you need.
