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

The designation of this NTN series consists of three parts separated by hyphens: the letter T, the letter E and a set of numbers with the suffix D. For example, in T-E-46791D/46720/46721D, the first block (46791D) identifies the inner cone, the second (46720) the cup and the third (46721D) the opposite cone. The final letter D indicates a design modification, generally related to geometry or surface treatment. This nomenclature allows each component of the assembly to be identified for replacement or inquiry.

In Argentine industry, these bearings are used in mining equipment, cement plants, crushing plants, mills, conveyor belts and agricultural machinery. Their ability to support combined loads and moments makes them suitable for high-demand applications, such as speed reducers, roller shafts and power transmission systems in environments with dust, vibration and variable temperatures.

To select the right bearing, take into account the radial and axial load, the rotation speed, the type of lubrication and the required sealing. The mounting must ensure precise alignment and correct fit between cone and cup. Lubrication can be with grease or oil, depending on the operating regime. It is essential to verify the internal clearance and mounting tolerances to avoid premature failures.

Double row tapered roller bearings may have equivalents with other brands, but it is essential to verify dimensions and tolerances before replacing.
