The TIMKEN tapered roller bearing is a component designed to support radial and axial loads in a single direction. Its construction with separable cone and cup allows precise mounting and controlled adjustment of internal clearance. It is used in applications where rigidity and load capacity are critical, such as transmissions, wheel axles and industrial machinery. MR Accesorios Industriales supplies this official brand and advises you to select the correct part number for your equipment.
The X#M series designation is interpreted as follows: the letter X indicates that it is a tapered roller cone, the central digits correspond to the size and the final letter M indicates a design modification, such as a surface treatment or a special tolerance. For example, X30309M and X30310M share the series but vary in dimensions. Knowing this nomenclature allows you to quickly identify the right replacement part.
In Argentine industry, TIMKEN tapered roller bearings are used in a wide variety of equipment: from gearboxes and drive axles to road, agricultural and earthmoving machinery. They are also present in the metalworking sector, in milling machine spindles and in conveyor rollers. Their ability to support combined loads makes them indispensable in applications where precision and durability are fundamental requirements.
To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. Mounting requires careful alignment and adjustment of internal clearance according to the equipment specifications. Proper lubrication, whether with grease or oil, extends service life. Check the sealing to prevent contamination from dust or moisture, especially in hostile environments.
TIMKEN tapered roller bearings can be interchanged with those of other brands that follow the same international nomenclature, such as SKF, FAG or NSK, as long as the dimensions and contact angle match. It is essential to verify the complete part number and tolerances before replacing. At MR Accesorios Industriales we indicate the compatible alternative or manufacture it to measure if necessary.
