When a shaft has to carry radial and axial forces at the same time in both directions, a TIMKEN double-row tapered roller bearing is often the answer: two rows of tapered rollers built into one unit. Typical homes for this design are gear reducers, mining and steel mill equipment, and other heavy machinery where stiffness and load capacity matter. MR Industrial Accessories supplies this line and helps buyers confirm the right configuration for their mounting.

Reading the code helps narrow down what you are looking at. The letters at the start of the designation place the bearing in the double-row tapered family, while the digits that follow relate to size and load capacity. A suffix such as NW marks a construction variant inside the series, and the examples show how the reference changes as sizes go up.

These bearings show up in demanding settings: mining machinery, steel plants, mills, conveyors and large agricultural equipment. Reducers and gearboxes that see combined loads and tilting moments are another common application. Because both rows sit in one assembly, a single double-row unit can take the place of two single-row bearings, which simplifies shaft design and frees up space.

Selection comes down to the loads involved, the speeds the shaft turns at, the lubrication planned and the sealing method. During mounting, the seats must be aligned carefully and axial clearance set as the manufacturer specifies. Good lubrication and effective sealing are what keep the bearing running in dusty, humid or temperature-variable conditions, and MR can advise on these points.

Double-row tapered roller bearings are made to dimensional standards that allow interchange between manufacturers. For a replacement, check the main dimensions, the contact angle and the load capacity, plus how the bearing is mounted. Codes are not always equivalent from one maker to another, so it pays to validate the application before swapping one reference for another.
