When a mounting has to take radial and axial forces at the same time in both directions, a TIMKEN double row tapered roller bearing is a common answer. Two rows of tapered rollers sit on one axis, giving the assembly the capacity and stiffness that gearboxes, mining equipment and heavy machinery demand. MR Industrial Accessories LLC supplies this line to customers in the United States and several Latin American countries.
The TD suffix in the part number tells you it is a double row unit. You will see it in references such as 688TD, 19146TD, 71457TD and 93826TD. The base number carries the size and geometry of the assembly, while the trailing letters confirm the two-row layout. When you pick a part number, start with the shaft diameter, then check the loads and the mounting type.
These bearings show up in mining, cement and steel operations, as well as in plants that build agricultural and road machinery. Typical locations include gearboxes, support rollers, overhead cranes and crushing equipment. Because they handle combined loads and moments, they fit mountings that call for high rigidity and rotational precision.
Sealing is a key part of selection. Depending on the environment, the bearing can run with radial shaft seals or other seal arrangements. The lubricant must match the operating speed and temperature. Shaft-to-housing alignment matters to avoid extra stresses, and internal clearance needs checking against the mounting. In double row arrangements, preload adjustment is often required to keep the assembly rigid.
Interchange between brands is possible when dimensions and load capacity line up. Still, tolerances and internal design can differ from one manufacturer to another, so compare the main dimensions and operating conditions before you commit. MR Industrial Accessories LLC can help you sort through the compatible options and suggest equivalents.

Frequently asked questions
- What does the TD suffix mean in these bearings?
- TD indicates a double row tapered roller bearing. This configuration supports radial and axial loads in both directions, with higher capacity than a single row. The base number identifies the size of the assembly.
- How do I choose the correct TIMKEN bearing for my equipment?
- You need the shaft diameter, radial and axial loads, rotation speed and environmental conditions. With that data, we will point you to the part number that best suits your application.
- Can I replace a bearing from another brand with a TIMKEN one?
- Yes, as long as the main dimensions and load capacity match. Verify tolerances and internal design. Send us the original part number and we will indicate the TIMKEN equivalent we supply.
