The FAG tapered roller bearing is a component designed to support radial and axial loads in one direction. Its internal geometry, with tapered rollers and raceways, allows linear contact that distributes the load better and provides high load capacity. It is used in applications with combined forces, such as reducers, wheel axles and industrial machinery. MR Accesorios Industriales sells this line as an official brand, with technical advice to choose the correct part number.

The designation K#-A-#-S reads as a tapered roller assembly. The initial letter K indicates that it is a single-row tapered roller bearing, with separable cone and cup. The middle block A usually identifies the contact angle or an internal design variant. The final suffix S may indicate a surface treatment or a special tolerance. A specific example is K387-A-382-S, where the numbers refer to the standardized dimensions of the cone and cup. To interpret each part number, the best option is to consult MR by WhatsApp.

This type of bearing is used in industries such as automotive, metalworking, mining and agro-industry. In Argentina it is commonly found in transmission cases, speed reducers, machine tool spindles, conveyor belt rollers and earthmoving equipment. It also appears in railway applications and construction machinery. Its ability to support combined loads makes it ideal for shafts that receive radial and axial forces at the same time, especially in assemblies where rigidity and precision are required.

To select a tapered roller bearing, radial and axial load, rotational speed and environmental conditions must be considered. Verifying sealing is essential: if the environment has dust or moisture, additional seals should be chosen. Mounting must ensure precise alignment between cone and cup, since these bearings are not self-aligning. Lubrication can be with grease or oil, depending on the application, and internal clearance must be adjusted carefully: excessive clearance generates vibrations and insufficient clearance raises temperature. At MR Accesorios Industriales we can guide you on these criteria.

Regarding equivalents, tapered roller bearings are manufactured under international standards that allow part numbers to be interchanged between different manufacturers, as long as the main dimensions and contact angle match. However, not all suffixes are equivalent: the same basic number can have variants in tolerances, treatments or cages. Therefore, when looking for a replacement, it is important to compare not only the numeric part number but also the additional letters.
