The TIMKEN TNA series double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on the same shaft, 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, final drives and heavy transmission equipment. MR Accesorios Industriales supplies this line as an official brand throughout Argentina.

The TNA series designation is interpreted from its letters and numbers. In the example HH221449NA, the initial letters indicate the assembly type and the dimension series, while the suffix NA identifies a construction variant within the family. The TNA series groups double row bearings with a machined cone and cup for direct mounting. To select the correct part number, take into account the bore diameter, the outside diameter and the total width your application requires.

In Argentine industry, double row tapered bearings are found in mining, cement, steel and material handling equipment. They also appear in speed reducers, mills, conveyor belts and large agricultural machinery. Their ability to withstand combined loads and moments makes them suitable for shafts where a single-row bearing cannot be used. MR Accesorios Industriales supplies them for plants and workshops throughout the country.

To choose correctly, verify the shaft diameter and the housing dimensions. The TNA series is mounted with an interference fit on the shaft and a sliding fit in the housing, depending on the load type. Lubrication can be grease or oil, and the sealing must protect against contaminants. Alignment between shaft and housing is critical: excessive misalignment shortens service life. If you need guidance, send us the dimensions or the part number on WhatsApp and we will indicate the compatible alternative.

TIMKEN TNA series bearings can be interchanged with equivalent products from other brands, provided the main dimensions and load capacity match. It is not enough for the part number to be similar: tolerances, contact angles and mounting type must be compared. At MR Accesorios Industriales we evaluate each case and offer the option that best suits your equipment, maintaining the original performance.
