NTN double-row tapered roller bearings are built to carry radial and axial forces in both directions at once. With two rows of tapered rollers, they deliver high load capacity and rigidity for applications that demand precision and durability, such as industrial machinery, mining equipment, cranes and transmission systems. MR Industrial Accessories supplies this line.

The part numbering follows a pattern you can read from examples like E-EE126096D/126150/126151D and E-EE134102D/134143/134144D. The leading E- denotes a special execution. Next comes a base code that identifies the assembly. The D suffixes point to internal design details of the series, including how the cones and cups are made. A complete code describes a ready-to-mount bearing with two rows of tapered rollers, and the nomenclature helps you pin down size and configuration.

These bearings suit equipment that sees combined loads and tilting moments: large gearboxes, mills, presses, port cranes and mining machinery. They also appear in steel, cement and heavy machinery manufacturing. When the right lubricant and sealing are chosen, they can operate in dusty, vibrating and high-temperature conditions.

Selection depends on load magnitude and direction, rotation speed and the surrounding environment. During mounting, alignment must be precise and axial clearance properly adjusted, usually with lock nuts or shims. Grease or oil lubrication is possible, and the sealing method should match the level of contamination exposure. Check that housings are concentric and follow the manufacturer's recommendations to avoid premature failure.

Double-row tapered roller bearings from different brands may be interchangeable when the main dimensions and load capacity align. Tolerances and internal designs differ, though, so it is wise to consult a specialist before swapping brands. MR Industrial Accessories can review compatibility and source the exact part number you need, whether you provide another brand's number or an unidentified part.
