NTN double row tapered roller bearings are high-capacity units designed to withstand radial and axial loads in both directions. Their construction with two rows of tapered rollers and inclined raceways allows superior performance in demanding applications. They are used in industrial machinery, mining, cement and steel equipment, where precision and durability are critical. MR Accesorios Industriales sells this line.

The designation of these bearings follows the NTN nomenclature for double row tapered rollers. The E- prefix indicates an improved design with higher load capacity. Part numbers that begin with LM and end in D correspond to the cone (inner ring) with two rows, while references without the D suffix identify the single cup (outer ring). The D suffix indicates an internal modification, such as a stronger cage or a surface treatment. In the examples, the combination of cone and cup defines the complete assembly, so it is essential to quote both components together.

These bearings are used in applications where high load capacities and rigidity are required, such as large gearboxes, cement mills, ore crushers, port cranes and earthmoving equipment. In Argentina, they are common in the mining industry of the Puna, in cement plants and in the steel sector. They are also found in machinery for the oilseed industry and in railway equipment. Their double row design makes it possible to replace two single row bearings in a reduced space, simplifying mounting and increasing the precision of the assembly.

To select the right bearing, it is key to consider the radial and axial load, the rotation speed and the environmental conditions. Mounting requires careful alignment and adequate lubrication, whether with grease or oil, depending on the application. Sealing is essential to prevent contamination by dust or particles, so evaluating the use of additional radial shaft seals is recommended. Internal clearance must be adjusted according to the equipment tolerances; excessive clearance can generate vibrations and reduce service life. Correct installation with appropriate tools and temperature control during operation ensure optimal performance.

As for equivalents, NTN double row tapered roller bearings can be interchanged with those of other leading brands, such as Timken, SKF or FAG, as long as the dimensions and load capacities are respected. It is important to verify the complete designation and the tolerances, since small differences in design can affect performance. If the customer has a part number from another brand, at MR Accesorios Industriales we can indicate the equivalent NTN reference. We also offer technical advice to select the best option for the application.
