The NTN double row tapered roller bearing E-M255449D/M255410/M255410DA is a pre-assembled unit that handles radial and axial loads in both directions. It suits gearboxes, final drives and mining equipment where high load capacity and rigidity are required.
Reading the designation helps you identify the components: the E-M prefix denotes the double row tapered roller series, while the numeric block E-M255449D/M255410/M255410DA corresponds to the cone-cup assembly. The suffixes D and DA indicate internal design variations, such as contact angle or fillet radius. Each part of the code identifies the cone, the cup and the spacer, which are supplied together to maintain the pre-adjusted axial clearance.
Typical applications include gearboxes in mills, crushers, conveyor belts, road machinery and earthmoving equipment, as well as mining, cement, steel and oilseed operations. The double row design can replace two single row bearings in one support, which simplifies shaft mounting where high rigidity and combined load capacity are needed.
Selection depends on radial and axial loads, rotation speed and environmental conditions. In dusty or humid environments, use high-viscosity grease and suitable seals. Mounting requires precise alignment and correct axial adjustment; too much or too little clearance reduces service life. Follow the manufacturer's pre-adjustment instructions.
Interchange between brands is possible when main dimensions and axial clearance match. When comparing equivalents, check the complete part number and verify tolerances and internal design. NTN offers suffix variants that may differ from other manufacturers. If you are unsure, send us the original part number and we will identify a compatible alternative.
