The double row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single unit, designed to withstand combined 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 this NTN line in Buenos Aires, Argentina, and quotes it via WhatsApp.
The designation of these bearings follows the NTN nomenclature for double row assemblies. In the examples, the prefix T- indicates an assembled unit, and the letters LM identify the dimension series. The numbers that follow, as in T-E-LM451349D/LM451310/LM451310D, correspond to the cones and cups that make up the assembly: the suffix D indicates a special execution, generally with a lubrication hole or groove. Knowing these codes allows you to identify each component and order the exact replacement.
These bearings are used in industries that demand robust power transmission: cement plants, steel mills, crushing plants, mills, cranes and railway equipment. In Argentina, they are common in speed reducers, support rollers of rotary kilns and main spindles of milling machines. Their ability to withstand loads in two directions makes them suitable for assemblies where other bearings would require more complex combinations.
To select the correct assembly, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Mounting requires precise alignment and proper adjustment of internal clearance, which is usually regulated with shims or precision nuts. Lubrication must be abundant and with the lubricant recommended by the manufacturer; sealing, if the equipment requires it, must protect against dust and moisture. Incorrect mounting shortens service life.
Double row tapered roller bearings can be interchanged between brands if the main dimensions and load capacity match. NTN, SKF, Timken, FAG and NSK offer equivalents, but tolerances and suffixes may vary. Always verify the complete part number and critical dimensions before replacing. If you have the part number from another brand, at MR Accesorios Industriales we will indicate the compatible alternative.

Frequently Asked Questions
- What does the suffix D mean in the designation?
- In the NTN nomenclature, the suffix D usually indicates a special execution of the ring, such as a lubrication hole or groove. In double row assemblies, each component may carry its own suffix. To interpret the exact code, ask us on WhatsApp.
- How do I choose between a double row bearing and two single row bearings?
- The double row bearing takes up less axial space and simplifies mounting, but requires more careful adjustment. Two single row bearings allow greater mounting flexibility and independent adjustment. The choice depends on rigidity and available space. We advise you according to your application.
- What lubricant do you recommend for these bearings?
- A high viscosity grease with EP additives is recommended for high loads, or circulating oil in high speed applications. The choice depends on temperature and speed. Follow the equipment manufacturer's instructions and ask us if you need a specific recommendation.
