RKB M series 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 withstand combined radial and axial loads, with high load capacity. They are used in applications where significant forces must be transmitted and alignment maintained, such as gearboxes, speed reducers and industrial equipment. MR Accesorios Industriales sells them in Buenos Aires, Argentina.

The M series designation is read in pairs of numbers separated by a slash: the first identifies the cone and the second the cup. For example, M 84548/510 indicates an M 84548 cone and an M 84510 cup; M 86647/610 combines the M 86647 cone with the M 86610 cup. The suffixes that appear in the series, such as ECP, EC, HJ or TMMA, correspond to cage, angle or machining variants. In the examples M 231649/610 and M 239449/410 the same logic applies: the first block is the cone and the second the cup. Knowing this logic lets you order the correct replacement without ambiguity.

These bearings are used in industries in Argentina such as metallurgy, cement, mining and food processing. They are found in speed reducers, gearboxes, overhead cranes, belt conveyors and crushing equipment. They are also found in agricultural machinery, such as seeders and combine harvesters, and in the oil & gas sector. Their ability to withstand combined loads makes them suitable for assemblies where the shaft takes radial and axial forces at the same time.

To select a tapered roller bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Mounting requires precise alignment and proper adjustment of the axial clearance, which is achieved by shimming the cone against the cup. Lubrication can be with grease or oil, depending on the equipment. Sealing is critical to prevent contamination with dust or moisture. In demanding applications, it is advisable to verify the rigidity of the assembly and the thermal expansion of the shaft.

As for equivalences, tapered roller bearings are identified by their numeric designation and by the main dimensions: bore diameter, outside diameter and width. When looking for a replacement, it is essential to respect those dimensions and the contact angle. Brands such as Timken, SKF, FAG, NTN or NSK sell equivalent series, but each manufacturer has its own codes. If you bring the code from another brand or an unidentified part, at MR we tell you the compatible alternative or quote the exact size you need.
