The TIMKEN TDO series double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on a common cone, 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, transmission shafts and industrial equipment. MR Accesorios Industriales supplies this line as a brand, with technical advice to select the right configuration.

The TDO series designation is structured with a prefix and a suffix that identify the size and features of the assembly. In the example LL771911CD, the initial letters indicate the dimension series, while the suffix CD indicates design particularities, such as the contact angle or the cage type. Knowing these codes allows you to correctly interpret the reference and request the exact replacement. If you have any doubts, send us the complete part number and we will tell you the compatible alternative.

These bearings are used in industries such as metallurgy, cement, mining and food processing, in equipment such as speed reducers, rotary kilns, conveyor belts and paper machines. In Argentina, they are common in the maintenance of mills, presses and heavy transmission systems. Their double row allows them to absorb combined loads and moments, making them suitable for shafts where alignment is not perfect.

To select a TDO, take into account the required load capacity, the operating speed and the environmental conditions. Mounting requires correct alignment of the seats and proper axial adjustment to distribute the load between the two rows. Lubrication can be grease or oil, depending on the operating conditions, and the sealing must be chosen to retain the lubricant and exclude contaminants. Careful mounting extends the service life of the assembly.

TIMKEN TDO series bearings can be interchanged with equivalents from other brands that follow the same dimensional nomenclature, although tolerances and capacities may vary. Therefore, when replacing, it is advisable to verify the critical dimensions and load conditions. MR Accesorios Industriales advises you to find the right option within its tapered roller bearing line.
