The NTN DU series double-row tapered roller bearing is a component designed to support radial and axial loads in both directions, with high load capacity and rigidity. It is used in applications requiring a compact and precise mounting, such as gearboxes, machine tool spindles and transmission equipment. Its two-row design allows replacing two single-row bearings with a single assembly, simplifying mounting and improving alignment.

The NTN DU series designation is interpreted from its examples: 430315DU, 430316DU, 430317DU and 430318DU. The first digits indicate the bearing type and its dimensional series, while the DU suffix indicates a specific design feature, such as sealing or the internal arrangement of the rows. To identify the exact variant you need, send us the complete part number and we will quote it.

These bearings are used in industries such as metallurgy, cement, mining and food processing, in equipment such as conveyor belts, mills, presses and gearboxes. In Argentina, they are common in heavy machinery maintenance and in production lines that demand high reliability. MR Accesorios Industriales sells them to supply both workshops and industrial plants.

To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Mounting requires careful alignment and adequate lubrication; in the DU series, the integrated sealing protects against contaminants. If the equipment operates at high temperatures or with vibration, it is advisable to verify the internal clearance and the type of grease. Our technical team can advise you according to your application.

Double-row tapered roller bearings can be interchanged between brands if the main dimensions and load capacity match.
