The TIMKEN TDI series is a double row tapered roller bearing built to handle combined radial and axial loads in both directions. It is selected for applications that call for high load capacity and rigidity, including gearboxes, drive shafts and various industrial machines. MR Industrial Accessories supplies this line.
Each assembly carries a TDI series designation plus its own part number. In 389DE, for example, the DE suffix indicates a double row configuration with matched cone and cup. Reading the code this way helps you quickly identify the bearing type and its internal arrangement, which simplifies comparison with other tapered roller variants.
TDI series bearings are found in speed reducers, mills, presses, cranes and mining equipment. Their capacity for combined loads suits drive shafts and support rollers in steel, cement and oilseed plants, where continuous operation places high demands on the bearing.
Proper selection depends on radial and axial load, rotation speed and the operating environment. During mounting, precise alignment and correct adjustment of internal clearance are essential, because tapered rollers run with a defined preload. Use the specified lubricant, and where seals are fitted, make sure they keep contaminants out.
Double row tapered roller bearings can be interchanged between brands when the main dimensions and load capacity match. Tolerances and clearances are set by each manufacturer, though, so it is wise to confirm the equivalent with a specialist before substituting. MR Industrial Accessories can help you find the compatible alternative.

Frequently asked questions
- What does the TDI series indicate in TIMKEN bearings?
- TDI designates double row tapered roller bearings that accommodate radial and axial loads in both directions. This arrangement provides high rigidity and load capacity for demanding applications.
- How do I select the correct TIMKEN TDI series bearing?
- You need the radial and axial load, speed and available space. With that information, we help you choose the right part number within the TDI series and its variants.
- Can a bearing from another brand be replaced by a TIMKEN TDI series bearing?
- Yes, if the dimensions and load capacity match. Always verify tolerances and internal clearance, since each manufacturer has its own specifications. We can advise you on a safe equivalent.
