The TIMKEN JM series double row tapered roller bearing is an assembly of two rows of tapered rollers mounted on a common axis, designed to carry radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, mining equipment and heavy machinery. MR Accesorios Industriales supplies this line with technical advice to select the right configuration.

The JM series designation is interpreted by its letters and numbers: the J indicates a series of tapered bearings with metric dimensions, the M indicates a medium load capacity, and the number that follows identifies the size. The final A suffix appears in references such as JM734449A and distinguishes design variants within the same series, for example, differences in contact angle or chamfer. To identify the exact part, simply provide the complete part number shown on the equipment or on the drawing.

These bearings are used in industries in Argentina such as mining, cement, steel and food. They appear in speed reducers, mills, conveyor belts, slurry pumps and crushing equipment. Their double row design allows replacing two single row bearings in a reduced space, simplifying mounting and increasing the rigidity of the assembly. In continuous production plants, this feature reduces maintenance times and improves equipment reliability.

To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. The 2TS-IM series is mounted with an interference fit on the shaft and controlled axial clearance; it is essential to verify the alignment between the shaft and the housing to avoid additional stresses. Lubrication can be with grease or oil, depending on the type of sealing. If the equipment works with contaminants, choose labyrinth seals or oil seals that protect the rollers and raceways.

As for equivalences, double row tapered roller bearings are identified by their designation and dimensions. When looking for a replacement, compare the bore diameter, the outside diameter and the total width, as well as the contact angle. Brands such as SKF, FAG, NSK or NTN offer similar products, but each has its own nomenclature. MR Accesorios Industriales indicates the alternative compatible with the part number you send us, without you needing to know the reference of other brands.

If you need this bearing or a variant of the JM series, write to us on WhatsApp and send us the complete part number, the dimensions or a photo of the part. At MR Accesorios Industriales we will quote it promptly and advise you so that the replacement is the correct one. We can also help you with the selection of seals, lubricants and mounting tools so that the replacement is done in a single operation.
