NTN DU series tapered roller bearings are separable bearings that support radial and axial loads in one direction. Their tapered raceway design and guided rollers allow linear contact that distributes load better than a ball bearing. They are used in applications with combined forces where rigidity is required, such as transmission cases, gear reducers, wheel hubs and motion equipment. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and quotes it on WhatsApp.

The DU series designation is read as follows: the initial numbers indicate the size and the dimensional series; for example, 30318DU and 30319DU correspond to single-row tapered roller bearings. The DU suffix identifies a design variant specific to NTN, generally associated with the treatment or the cage. To correctly interpret each code, note that the first two digits usually indicate the diameter series and the following ones the size. If you need to confirm the exact equivalent, send us the complete code on WhatsApp and we will quote it.

In Argentine industry, tapered roller bearings are found in speed reducers, gearboxes, transmission shafts, mining equipment, cement plants and food plants. They also appear in wheel hubs of commercial vehicles and in agricultural machinery, where combined loads and shocks are frequent. The NTN DU series is chosen when a robust bearing is needed, with good load capacity and the possibility of adjustment. MR Accesorios Industriales supplies this line for replacement and maintenance in Buenos Aires, Argentina and the rest of the country.

To select a tapered roller bearing, consider the radial and axial load, the rotation speed and the type of lubrication. These bearings are usually mounted in pairs, facing each other, to absorb loads in both directions; internal clearance is adjusted with shims or nuts. It is important to verify the alignment of the shaft and the housing, because they are sensitive to misalignment. Proper sealing and lubrication extend service life. If you have doubts about mounting, ask us and we will advise you.

Tapered roller bearings are manufactured under international standards, which facilitates interchangeability between brands.
