The cone of a tapered roller bearing is the inner ring that fits on the shaft. Paired with its cup, it creates a bearing assembly that handles radial and axial loads together, which a deep groove ball bearing does not manage as effectively. Typical uses include gearboxes, wheel hubs, and transmission equipment where thrust and rigidity matter.

The LM AX series code breaks down into sections. The first letters indicate the size family and the cone type, while the AX suffix marks a specific design within that family. In LM451349AX, the digits in the middle set the size order. When you need a replacement, provide the full part number. Each cone is designed to work with a particular cup, and mixing components from different series is not recommended.

These cones are common in gearboxes and gear cases, wheel hubs on road and agricultural machinery, conveyor rollers, mills, and machine tools. They also appear in process pumps and heavy fans where axial thrust is continuous. Because they are wear parts, replacement by part number is a normal part of maintenance and planned shutdowns.

For correct selection, consider the cone diameter and width, the contact angle, and the matching cup-and-cone set. Installation calls for cleanliness, an interference fit on the shaft, and lubrication chosen for the operating temperature and speed. Proper alignment between cup and cone is essential; misalignment speeds up wear on the raceway and rollers. Also check the sealing of the assembly to keep contaminants out.

When it comes to equivalents, tapered roller bearings are identified by the manufacturer's part number and by standardized dimensions. The same size may carry different designations across brands. Do not cross-reference codes just by appearance; true interchangeability depends on dimensions and on the cup-and-cone pair. If you need to replace a reference, send us the original part number and we will point you to a compatible option.

If you have the cone part number or the equipment model, send it by WhatsApp or email to MR Industrial Accessories. We will quote it promptly and can also verify the corresponding cup and put together the complete set. We work with leading brands to meet your equipment replacement needs.
