The tapered roller bearing is a component designed to support combined radial and axial loads, with a high load capacity relative to its size. It is used in applications where there are significant stresses and high rigidity is required, such as gearboxes, reducers, wheel axles and industrial machinery. MR Accesorios Industriales sells NTN bearings from this family, with more than 80 years of experience in the Argentine market.

The designation of these bearings combines a basic number with suffixes that indicate construction characteristics. For example, in 4T-30304CA and 4T-30306CA, the prefix 4T- identifies the tapered roller series, while the central number (30304, 30306) defines the size and dimension series. The suffix CA indicates a specific variant, usually linked to the contact angle or internal design. Knowing these codes allows you to select the right bearing for each application.

In Argentine industry, NTN tapered roller bearings are used in a wide variety of equipment: vehicle gearboxes, speed reducers, road machinery, railway equipment, mills, presses and industrial transmissions. Their ability to support combined loads makes them indispensable in applications where shafts are subjected to simultaneous radial and axial stresses, such as in motor vehicle wheels or machine tool spindles.

To correctly select a tapered roller bearing, it is essential to consider the mounting arrangement (in pairs, face-to-face or matched), the type of sealing (open, with oil seals or with shield plates), the internal clearance and adequate lubrication. Precise alignment between the shaft and the housing is critical to avoid parasitic loads and extend service life. In matched mountings, it is recommended to adjust the axial clearance according to the manufacturer's specifications.

NTN tapered roller bearings can be interchanged with those of other recognized brands, as long as the main dimensions (bore, outer diameter and width) and tolerances are respected. Dimension series are usually standardized, which facilitates equivalence between different manufacturers. If the customer has the code of another brand or an unidentified part, at MR Accesorios Industriales we can indicate the compatible alternative.
