The TIMKEN TNASW 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, mining equipment, steelmaking and heavy machinery. MR Accesorios Industriales supplies this line as an official brand in Buenos Aires, Argentina.
The TNASW series designation is read in blocks: the letters TNA identify the double row tapered roller bearing family, the S indicates the single unit design (without a separate cone) and the W corresponds to a sealing or cage variant depending on the manufacturer. The numbers that follow, as in the examples NA435SW, NA438SW or NA455SW, indicate the size and mounting dimensions. Each suffix can change the type of sealing, the internal clearance or the precision; therefore, when requesting a quote, it is best to send the complete code.
These bearings are used in industries that demand reliability under severe loads: mining, cement, steelmaking, paper, cranes and material handling equipment. In Argentina, they are commonly found in speed reducers, kiln rollers, mills, presses and road machinery. Their double row allows replacing two single row bearings in a single housing, simplifying the design and improving the rigidity of the assembly. MR Accesorios Industriales supplies them for plants that need critical spare parts with brand traceability.
To correctly select a TNASW bearing, take into account the radial and axial load, the rotation speed, the lubrication and the type of sealing. The double row requires careful alignment of the shaft and the housing; any misalignment accelerates wear. Mounting must be done with suitable tools, without striking the rings, and with the internal clearance verified according to the application. Lubrication can be grease or oil, and sealing will depend on the environment: dust, water or temperature. If in doubt, the complete code is the best guide.
As for equivalents, double row tapered roller bearings are interchanged between manufacturers if dimensions, load capacity and sealing configuration match. It is not enough for the number to be similar: tolerances and clearance must be compared. TIMKEN is a world reference in this family, and MR Accesorios Industriales supplies it as an official brand. If you need to replace a bearing from another brand, send us the original code and we will indicate the compatible alternative.
