The double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on a common shaft, designed to withstand radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gear reducers, final drives and mining equipment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, and advises you on selecting the correct code for your application.

The designation of these bearings follows NTN nomenclature: the prefix E- indicates a special execution, followed by the size series (for example, M278749D) and the suffix that identifies the cone, the cup and the assembly. In the example code E-M278749D/M278710/M278710DAG2, the segments separated by slashes correspond to the cone, the cup and the complete assembly. The suffix D indicates a double row design, and AG may refer to a cage or treatment variant. Get to know the series by its letters and ask for the exact code shown on your equipment.

These bearings are used in industries in Argentina such as mining, cement, steel and earthmoving. They are found in speed reducers, gearboxes, support rollers, overhead cranes and railway equipment. Their ability to withstand combined loads and moments makes them suitable for assemblies where alignment is critical and high rigidity is required. MR Accesorios Industriales provides solutions for these applications with NTN's backing.

To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Assembly must guarantee precise alignment; it is recommended to check the internal clearance and use the appropriate lubricant according to temperature and contamination. Sealing is key: in dusty or humid environments, choose configurations with radial shaft seals. Lubrication can be grease or oil, and relubrication must follow the manufacturer's instructions. Assembly with a hydraulic press and calibration prevents damage to the raceways.
