The cone is the inner component of the tapered roller bearing: it includes the inner race, the rollers and the cage. It is mounted together with the cup, which is the outer race, and together they form a unit that supports combined radial and axial loads. The Timken X series identifies cones widely used in industrial and automotive applications. MR Accesorios Industriales carries this line in Buenos Aires, Argentina, and advises you to choose the correct cone for your equipment.

The X series designation is read by the base number that identifies each cone: 246X, 342X, 355X, 358X, 367X, 385X, 525X, 529X. In Timken nomenclature, that number is not an arbitrary code: it relates to the main dimensions of the cone, such as the bore diameter and the width. The final letter X indicates a construction variant within the same family. To select the correct cone, the safest approach is to start from the number that appears on the original bearing or in the equipment manual, and cross-reference it with the corresponding cup.

X series tapered roller cones are used in a wide variety of industrial equipment in Argentina: gearboxes and transmission cases, road machinery axles, conveyor belt rollers, milling equipment, centrifugal pumps and automotive applications. They also appear in agricultural machinery, such as seeders and harvesters, where combined loads and demanding working conditions require robust bearings. As a wear component, replacement with the correct reference is key to maintaining the service life of the assembly.

To choose the cone correctly, take into account the cup it is mounted with: cone and cup are selected as a set and it is not advisable to mix parts from different series without verifying compatibility. Check the condition of the race, the rollers and the cage; if there is pitting, irregular wear or excessive play, replace the complete assembly. During mounting, ensure correct alignment and adequate lubrication: tapered rollers work best with clean lubricant in sufficient quantity. Poorly adjusted axial clearance accelerates wear and can damage the equipment.

As for equivalents, tapered roller bearings are identified by numbering systems that vary between manufacturers. The same number may correspond to similar but not identical dimensions, so interchangeability between brands must always be verified with the cone and cup measurements. Timken is a world reference in this technology, and MR Accesorios Industriales carries it as an official brand. If you need to replace a bearing from another brand, write to us with the original part number and we will indicate the compatible alternative.

If you are looking for a cone from the X series, send us the exact part number that appears on your equipment or on the old bearing. At MR Accesorios Industriales we quote it on WhatsApp shortly and help you confirm that it is the correct part. We can also advise you on the corresponding cup and the suitable lubricants for mounting. Write to us with the reference and we will reply.
