When a shaft has to handle radial and axial forces at the same time, the TIMKEN TDO series double row tapered roller bearing is a common choice. It consists of two rows of tapered rollers on one shared cone, which gives the assembly rigidity and load capacity for gearboxes, transmission shafts and other industrial equipment. MR Industrial Accessories supplies this line and can help you confirm the correct configuration.
The TDO reference follows a pattern: a prefix and a suffix describe the assembly. In LL771911CD, the leading letters belong to the dimension series, and the CD ending points to design details such as contact angle or cage style. Reading those codes correctly is what lets you order the exact replacement. If the reference is unclear, send the full part number and we will identify a compatible option.
You will find these bearings in metalworking, cement, mining and food processing plants, installed in speed reducers, rotary kilns, conveyor systems and paper machines. The double row arrangement handles combined loads and moments, so it suits shafts where alignment is less than perfect.
Selection depends on load capacity, operating speed and the environment around the bearing. During mounting, the seats must be aligned and the axial setting adjusted so both rows share the load. Grease or oil can be used for lubrication, and the seal type should keep lubricant in and contaminants out. Careful installation has a direct effect on how long the assembly lasts.
TIMKEN TDO bearings can be replaced with equivalents from other manufacturers that use the same dimensional nomenclature, but tolerances and capacities are not always the same. Before substituting, check the critical dimensions and the load conditions. MR Industrial Accessories can guide you through its tapered roller bearing range to find a suitable option.

Frequently asked questions
- What does the TDO designation mean in a TIMKEN bearing?
- TDO refers to the series of double row tapered roller bearings that share a common cone. The full code contains letters and numbers that define dimensions and features. Send us the reference and we will help you identify the replacement.
- How do I choose the right double row tapered roller bearing for my machine?
- Look at the radial and axial load, speed, available space and lubrication conditions. Mounting type and alignment also matter. With that information, we can recommend the TDO configuration that best suits your equipment.
- Are TIMKEN TDO bearings interchangeable with other brands?
- They can be interchanged with bearings of equivalent dimensions from other brands, but check tolerances and load capacity. Not all series are identical. If you send us the original part number, we will tell you the compatible alternative.
