RKB tapered roller bearings are separable units made up of a cone (inner ring with rollers and cage) and a cup (outer ring). They are designed to support radial and axial loads in one direction, so they are mounted in opposed pairs. They are used in applications with combined loads, such as gearboxes, wheel axles and transmission machinery. MR Accesorios Industriales sells them in Buenos Aires, Argentina, and quotes them via WhatsApp.

The designation of these tapered bearings is read as a fraction: the first number identifies the cone and the second the cup. In the examples 462/453 X, 535/532 X and 539/532 X, the slash separates both components, which are supplied as a set. The suffix X indicates that the external dimensions follow the international standard, which facilitates interchange. Knowing this logic allows you to order the correct replacement even if you only have the number of one of the two parts engraved.

These bearings are used in industries in Argentina such as food, cement, mining and metalworking. They are present in speed reducers, transmission boxes, wheel axles of road and agricultural equipment, and in machine tools. Their ability to combine radial and axial load makes them suitable for helical and bevel gears, where forces are not purely radial. They are also found in large pumps and fans.

To select a tapered roller bearing, take into account the radial and axial load it must support, the rotation speed and the available space. Mounting requires careful alignment and controlled axial adjustment: it is recommended to mount two bearings in opposition and adjust clearance with nuts, shims or covers. Lubrication can be with grease or oil, and sealing must be chosen according to the environment. An interference fit on the cone and a sliding fit on the cup facilitate disassembly.

When looking for a replacement, it is common to find equivalences between different brands that manufacture tapered roller bearings with the same standardized dimensions. If you bring the part number of another brand or an unidentified part, at MR Accesorios Industriales we will indicate the compatible alternative. Interchangeability is based on the cone and cup dimensions, not on the catalog number, so it is advisable to verify the diameters and total width before replacing.
