The cone is the inner component of a tapered roller bearing: it includes the inner ring, the rollers and the cage. It is mounted together with the cup (outer ring) to form the assembly that supports combined radial and axial loads. The NSK JM series is used in applications requiring high load capacity and rigidity, such as gearboxes, wheel axles and transmission equipment. If you need the cone for a specific piece of equipment, at MR Accesorios Industriales we quote the exact part number.

The JM series designation is read as a code that identifies the size and design of the cone. For example, JM 734449, JM 738249 and JM 822049 are references that share the JM series and vary in their dimensions. The numbers following the letters indicate the size and particular geometry of each cone. To select the correct one, take into account the full part number shown on the original bearing or in the equipment manual.

These cones are used in industries such as metallurgy, food, mining and plastics, in equipment such as conveyor belts, mills, presses and machine tools. In Argentina, they are commonly found in speed reducers, overhead cranes and agricultural machinery. Their design allows them to withstand combined loads and slight misalignments, making them a frequent choice in power transmissions.

For mounting, make sure the cone and cup are clean and free of burrs. Proper lubrication is key: use the grease or oil recommended by the equipment manufacturer and check the axial clearance after adjustment. Alignment between the cone and cup must be precise to avoid premature wear. If the bearing operates in contaminated environments, consider additional seals. Always follow the maintenance manual instructions.

Tapered roller bearings are manufactured under interchangeability standards, so a cone from one brand can be mounted with a cup from another brand if they share the same dimensions and angle. However, to ensure performance, it is advisable to replace the complete assembly. If you have another brand's part number, at MR Accesorios Industriales we can tell you the compatible equivalent.
