The cone is the inner component of a tapered roller bearing: it comprises the inner cone, the cage and the rollers. It is mounted on the shaft and works together with the cup, which sits in the housing. It supports radial and axial loads in one direction, which is why it is used in pairs. In Argentina it is used in gearboxes, machine shafts and industrial equipment that demand high load capacity and rigidity.

The designation of these NSK cones is expressed with numbers, such as 780, 782, 787, 861, 938, 1779, 1988 or 02473. Each code identifies a specific cone geometry: bore diameter, width and roller angle. In tapered roller bearings, the cone and cup are ordered separately; the cone number does not always match the cup number. To assemble the complete bearing, both codes must be combined, and they usually share a series. If you have the cone code, we can quote it via WhatsApp.

These cones are used in applications with combined loads and tilting moments. In Argentine industry they appear in speed reducers, transmission boxes, machine tool shafts, material handling equipment, pumps and industrial fans. Also in the agro-industrial sector, in seeders and harvesters, and in crane and conveyor assemblies. Their ability to support simultaneous radial and axial loads makes them suitable for shafts rotating at moderate speeds with rigidity requirements.

To select the correct cone, take into account the shaft diameter, the total mounting width and the type of load. Mounting is done with an interference fit on the shaft, using controlled heating or a press, and the cup is fitted into the housing. Lubrication can be grease or oil, depending on speed and temperature. Precise alignment is essential to avoid parasitic loads. Sealing prevents contamination and lubricant loss. If mounting in pairs, respect the axial clearance recommended by the manufacturer.

Tapered roller bearings are manufactured under dimension and tolerance standards that allow interchangeability between brands. An NSK cone can be replaced by the equivalent from another brand as long as the dimensions and angle match. To find the equivalent, the codes and measurements must be compared. If you bring the code from another brand or an unidentified part, at MR Accesorios Industriales we will indicate the compatible alternative. We do not invent codes: we work with standardized designations.

To request a quote for the cone you need, send the code via WhatsApp to MR Accesorios Industriales. If you do not have it at hand, provide the shaft and housing measurements, or the cup number if you know it. We will reply shortly with the quote. We can also advise you on mounting and the appropriate lubrication for your application. With more than 80 years in the business, at MR Accesorios Industriales we know the needs of Argentine industry.
