For equipment that must handle radial and axial forces simultaneously, the TIMKEN JM series double row tapered roller bearing offers a compact solution. This assembly places two rows of tapered rollers on a common axis, providing the rigidity and load capacity needed in gearboxes, mining machinery and other heavy-duty applications. MR Industrial Accessories supplies this line and can help you specify the correct configuration for your equipment.

The JM series part number carries specific meaning. The letter J denotes a metric tapered bearing series, M indicates medium load capacity, and the following digits specify the size. When an A appears at the end, as in JM734449A, it signals a design variation within the same series, such as a different contact angle or chamfer. To identify the exact bearing, provide the full part number from the equipment or drawing.

These bearings are common in mining, cement, steel and food processing operations. They are found in speed reducers, mills, conveyors, slurry pumps and crushing equipment. Because the double row design can replace two single row bearings in less space, it simplifies mounting and increases assembly rigidity. In continuous production plants, this can reduce maintenance time and improve equipment reliability.

Selection depends on radial and axial loads, rotational speed and environmental conditions. The 2TS-IM series is mounted with an interference fit on the shaft and controlled axial clearance; verifying alignment between shaft and housing is critical to avoid added stress. Lubrication may be grease or oil, depending on the sealing method. In contaminated environments, labyrinth seals or oil seals protect the rollers and raceways.

For replacements, double row tapered roller bearings are identified by designation and dimensions. When comparing, check bore diameter, outside diameter, total width and contact angle. Other brands such as SKF, FAG, NSK or NTN offer similar products, but each uses its own nomenclature. MR Industrial Accessories can suggest a compatible alternative based on the part number you provide, without requiring you to know other brands' references.

If you need this bearing or a JM series variant, contact us via WhatsApp with the complete part number, dimensions or a photo of the part. We will quote it promptly and advise you to ensure the replacement is correct. We can also assist with the selection of seals, lubricants and mounting tools so the replacement is completed in a single operation.
