The double row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single frame, allowing 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 spindles and mining equipment. MR Accesorios Industriales sells the NTN line with technical advice to select the correct part number according to the application.

The designation of these NTN bearings is structured with a prefix and two sets of numbers separated by slashes. For example, in E-67791D/67720/67721D, the prefix E indicates a special execution, while the numbers identify the dimensions and internal design of each row. Suffixes such as D indicate variants in the roller design or heat treatment. Each complete part number defines a specific assembly, so it is essential to respect the nomenclature when requesting a quote.

In Argentine industry, these bearings are used in mining equipment, cement plants, steel mills and machine tool manufacturing. They are also found in large gearboxes, overhead cranes and power transmission systems that operate with combined loads and require high precision. Their ability to support axial loads in both directions makes them suitable for applications where other types of bearings do not perform in the same way.

To select the correct bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting requires careful alignment and proper adjustment of the internal clearance, which is usually regulated by shims or lock nuts. Lubrication must be the one indicated by the manufacturer, and sealing will depend on exposure to dust or moisture. Incorrect mounting can reduce the service life of the bearing.

Double row tapered roller bearings may have equivalents across different brands, but each manufacturer defines its own tolerances and load capacities. Therefore, if you need to replace a bearing from another brand, the best option is to send us the complete part number or the main dimensions so we can quote you the equivalent NTN option. Not all series are interchangeable without verifying the fits.
