The tapered roller bearing is a component designed to support combined radial and axial loads. Its internal geometry, with tapered rollers and raceways, allows linear contact that distributes the load and provides high load capacity. It is used in applications requiring rigidity and precision, such as transmission cases, gearboxes, wheel axles and industrial machinery. At MR Accesorios Industriales we sell the RKB brand and we quote the part number you need.

The designation of RKB tapered roller bearings follows the usual nomenclature for this type of bearing. In the case of the A series, the part numbers consist of a letter and a number, as in the example A 4059/A 4138. This structure indicates that it is a cone and cup assembly, where each part has its own designation. Any suffixes that may appear in other part numbers provide information about the internal design, such as the contact angle or the surface finish, but it is always advisable to verify the complete designation at the time of your inquiry.

These bearings are used in a wide variety of industries in Argentina. They are common in vehicle gearboxes, speed reducers, machine tool spindles, mining equipment, cranes and agricultural machinery. Their ability to support combined loads and their rigidity make them suitable for applications where shafts must maintain precise alignment under varying loads. They are also used in conveyor rollers and material handling equipment.

To correctly select a tapered roller bearing, take into account the radial and axial load it must support, the rotational speed and the environmental conditions. It is essential to ensure adequate lubrication, whether with grease or oil, and to maintain effective sealing to prevent contamination. Mounting requires precise alignment and correct adjustment of the internal clearance, which can be regulated with shims or nuts. Improper mounting can reduce the service life of the bearing.

Regarding equivalences and interchangeability, tapered roller bearings are manufactured according to international standards that allow one brand to be replaced by another as long as the main dimensions and the contact angle match. If you have the part number of another brand, we can help you find the equivalent RKB reference. It is important to verify the tolerances and the internal clearance to ensure optimal operation.
