The cone is the inner ring of the tapered roller bearing, the part that is mounted on the shaft and that together with the cup forms the assembly. Its tapered raceway and rollers absorb combined radial and axial loads, something a deep groove ball bearing does not handle with the same efficiency. It is used in applications with axial thrust and rigidity requirements, such as gearboxes, wheel hubs and transmission equipment.

The LM AX series designation is read in blocks: the initial letters identify the dimension family and the cone type, and the AX suffix indicates a construction variant within that family. In the example LM451349AX, the central number orders the size within the series. To order the correct replacement, it is enough to provide the complete part number, because each cone is mounted with a specific cup and components from different series should not be mixed.

In Argentine industry these cones appear in gearboxes and gear cases, wheel hubs of road and agricultural equipment, conveyor belt rollers, mills and machine tools. Also in process pumps and heavy fans, where axial thrust is constant. As it is a wear component, replacement by part number is common in maintenance and scheduled shutdowns.

To select correctly, take into account the cone diameter and width, the contact angle and the corresponding cup-and-cone pair. Mounting requires cleanliness, interference fit on the shaft and adequate lubrication according to temperature and speed. Alignment between cup and cone is critical: misalignment accelerates wear of the raceway and the rollers. Also check the sealing of the assembly to prevent contaminant ingress.

Regarding equivalences, tapered roller bearings are identified by the manufacturer's part number and by standardized dimensions, so the same size may appear with different designations depending on the brand. Codes should not be cross-referenced by similarity: real interchangeability is defined by dimensions and by the cup-and-cone pair. If you need to replace a reference, send us the original part number and we will indicate the compatible alternative.

If you have the cone part number or the equipment model, send it by WhatsApp to MR Accesorios Industriales and we will quote it promptly. We can also verify the corresponding cup and assemble the complete set. With more than 80 years in the industry, at MR Accesorios Industriales we work with leading brands and in-house manufacturing to solve the replacement needs of your equipment.
