TIMKEN TDO series bearings are double-row tapered roller units supplied as a matched cone and cup assembly. They suit shafts that need accurate guidance while carrying radial and axial forces in both directions, which is common in gearboxes, mining machinery, mills and other heavy equipment. MR Industrial Accessories supplies this line and can help you match the right size to your application.

In the TIMKEN naming system, TDO points to a double-row tapered roller bearing family. A complete identification usually combines that code with the bore size and the overall width. When you ask for a quote, the clearest path is to send either the full part number or the three key dimensions: shaft diameter, outer diameter and width. That information lets us pin down the exact variant you need.

These bearings tend to appear where combined loads and stiffness matter: cement works, mining operations, steel mills, paper machines, cranes and material handling systems. You will also find them in gearboxes, support rollers, large pulleys and machine tool spindles. Because two rows are built into one unit, a single TDO can take the place of two single-row bearings, which simplifies shaft design and frees up space.

Selection should account for the radial and axial loads involved, the operating speed and the surrounding environment. Correct alignment during mounting and suitable lubrication, grease or oil as the equipment requires, are both important. Protection against dust and moisture also matters, since contamination shortens bearing life. If the shaft sees thermal expansion, review the internal clearance and the fit type.

TIMKEN is a well-known name in tapered rollers, and equivalents from other manufacturers often exist, though they are not always a direct swap. Contact angles, corner radii and tolerances can differ. If you are replacing a bearing from another brand, compare dimensions and load ratings before committing. Our team can assist with that comparison.

To request a TIMKEN TDO series bearing, message us on WhatsApp with the part number or the dimensions you have. We will reply promptly and help confirm the variant fits your equipment. You can also ask about other tapered roller series or bearings in general, since we carry a broad range for industry.
