The double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on the same axis of symmetry, designed to support combined radial and axial loads in both directions. It is used in equipment where a single row is not enough due to load capacity or rigidity requirements, such as gearboxes, road machinery drives and rolling mills. MR Accesorios Industriales sells the TIMKEN brand in Buenos Aires, Argentina.

The designation of this family is read in blocks: the initial letters identify the dimension series and the numeric block that follows defines the size within that series. In the HH series, examples such as HH224346DD show the series prefix followed by the assembly number; the suffix DD indicates double row. When the code includes additional letters, they usually refer to design variants of the assembly, not to different dimensions. To request a quote, send us the complete code as it appears on the equipment.

These bearings appear in applications with combined loads and moments: mill reduction gearboxes, conveyor belt drives, road and agricultural machinery, earthmoving equipment and rolling mills. In Argentina they are seen in cement, oilseed, steel plants and in the mining sector. Also in crane drives and in support rollers of heavy equipment, where the double row allows distributing the load and gaining rigidity compared to an arrangement of two single bearings.

To select well, you must look at the type of load, rotation speed and environment. The double row works best with abundant lubrication and adequate sealing against dust and water, especially in environments with particulate material. Mounting requires aligning the seats and controlling axial clearance according to the equipment design: excessive adjustment accelerates wear and a loose one generates vibration. Lubrication can be grease or oil depending on the housing, and it is advisable to respect the interval indicated by the equipment manufacturer.

Regarding equivalences, each manufacturer builds its own nomenclature for double row tapered roller bearings, so the same size can appear with different codes depending on the brand. Interchangeability is defined by mounting dimensions and load capacity, not by the similarity of the code. If you need to replace a bearing and cannot find the exact reference, send us the measurements or the old code and we will indicate the compatible alternative.

If you have the bearing code at hand, write to us on WhatsApp and we will quote you shortly. We can also advise you on mounting, lubrication and sealing so that the assembly works under the correct conditions. MR Accesorios Industriales works with leading brands and in-house manufacturing to cover the needs of industrial maintenance throughout the country.
