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 delivers 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 backed by more than 80 years in the Argentine market.

The designation of these bearings follows NTN nomenclature for double row tapered rollers. The prefix E- indicates an improved design with higher load capacity. Codes such as LM258649D, LM274449D or LM665949D correspond to the cone (inner ring) with two rows, while references LM258610, LM274410 or LM665910 identify the single cup (outer ring). The suffix D 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 request a quote for both components together.

These bearings are used in applications requiring high load capacities and rigidity, such as large gearboxes, cement mills, ore crushers, port cranes and earthmoving equipment. In Argentina, they are common in the Puna mining industry, 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 allows replacing two single row bearings in a reduced space, simplifying assembly and increasing the precision of the assembly.

To select the right bearing, it is key to consider radial and axial load, rotation speed and environmental conditions. Assembly 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 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 suitable 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 dimensions and load capacities are respected. It is important to verify the complete designation and tolerances, since small differences in design can affect performance.
