In a tapered roller bearing, the cone is the inner assembly: the inner ring, the cage and the rollers travel together as one unit. It sits on the shaft, while the cup presses into the housing. Because this design carries radial and axial load in a single direction, cones are normally installed in pairs. Typical duty includes gearboxes, machine shafts and industrial equipment that calls for rigidity and load capacity.

NSK identifies these cones by numeric codes such as 780, 782, 787, 861, 938, 1779, 1988 and 02473. Each code describes a particular cone geometry, covering bore, width and roller angle. Cone and cup are purchased as separate items, and the two numbers do not always match, so the complete bearing is defined by pairing both codes, generally from the same series. Send us the cone code and we will quote it.

Where combined loads and tilting moments are present, this cone type is a common choice. It appears in speed reducers, transmission boxes, machine tool shafts, material handling equipment, pumps and industrial fans, as well as in seeders, harvesters, cranes and conveyor assemblies. Shafts that turn at moderate speed but need rigidity are a good fit for this design.

Selection starts with the shaft diameter, the total mounting width and the nature of the load. The cone is fitted to the shaft with interference, using controlled heat or a press, and the cup goes into the housing. Grease or oil both work as lubricants, depending on speed and temperature. Alignment must be precise so that parasitic loads do not appear, and sealing keeps contamination out and lubricant in. When cones are mounted in pairs, follow the axial clearance given by the manufacturer.

Tapered roller bearings are produced to dimension and tolerance standards that make brands interchangeable. An NSK cone can be swapped for an equivalent from another maker when dimensions and angle agree, which means comparing codes and measurements. Bring us a code from a different brand or an unidentified part and we will point out the compatible alternative, since we work with standardized designations.

To get a quote, send the cone code by WhatsApp or email. If you do not have it, send the shaft and housing dimensions, or the cup number if you know it. The team replies promptly, can advise on mounting and lubrication, and can suggest equivalents and help you choose.
