For equipment that must carry radial and axial forces simultaneously, the NTN DU series double-row tapered roller bearing offers a compact, rigid solution. Its two rows work together in both directions, so one bearing can often take the place of two single-row units. This simplifies mounting and helps maintain alignment in gearboxes, machine tool spindles and transmission systems.

The DU series covers part numbers such as 430315DU, 430316DU, 430317DU and 430318DU. In these designations, the initial digits identify the bearing type and dimensional series, while the DU suffix points to a particular internal design or sealing arrangement. If you need the exact variant, send the full part number and we will quote it.

These bearings appear in demanding sectors including metallurgy, cement, mining and food processing. Typical equipment includes conveyor belts, mills, presses and gearboxes. Maintenance teams rely on them for heavy machinery and production lines where reliability matters. MR Industrial Accessories supplies them to workshops and industrial plants.

Choosing the correct bearing starts with the radial and axial loads, the operating speed and the surrounding conditions. Proper alignment during mounting and sufficient lubrication are essential. In the DU series, the integrated sealing helps keep contaminants out. For high-temperature or high-vibration applications, check the internal clearance and grease type. Our technical team can help you match the bearing to your specific use.

Double-row tapered roller bearings from different brands can often be interchanged when the main dimensions and load ratings align. When seeking a replacement, compare the original part number against equivalence tables, but always verify tolerances and internal design. If you are unsure, send us the original part number and we will suggest a compatible alternative.
