The double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on a common shaft, designed to support radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, final drives and mining equipment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The designation of this series is read in blocks: the initial letters E-M identify the double row tapered roller series; the number that follows, as in E-M255449D/M255410/M255410DA, corresponds to the cone-cup assembly. The suffixes D and DA indicate internal design variants, such as contact angle or fillet radius. Each block identifies the cone, the cup and the spacer, which are supplied as an assembly to guarantee the pre-adjusted axial clearance.

These bearings are used in industries in Argentina such as mining, cement, steel and oilseed. They are present in gearboxes of mills, crushers, conveyor belts, road machinery and earthmoving equipment. Their double row allows replacing two single row bearings in a single support, simplifying the design and mounting on shafts that require high rigidity and combined load capacity.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing and lubrication are critical: in environments with dust or humidity, lubrication with high-viscosity grease and suitable seals is recommended. Mounting must ensure precise alignment and correct axial adjustment; excessive or insufficient clearance shortens service life. Follow the manufacturer's instructions for pre-adjustment.

Double row tapered roller bearings can be interchanged between brands if the main dimensions and axial clearance match. When looking for equivalents, compare the complete part number and verify the tolerances and internal design. NTN offers this line with suffix variants that may differ from other manufacturers. If you have doubts, consult us with the original part number and we will indicate the compatible alternative.
