When you need one bearing that handles radial and axial forces in both directions, a double row tapered roller bearing is the answer. Timken builds these assemblies with two rows of tapered rollers in a single unit, providing high capacity and rigidity for gearboxes, transmission shafts, and mining equipment.
Timken part numbers for these bearings follow a clear pattern. The L…D series includes L116110D, L163149D, and L217810D. The letter and digits give the main dimensions, while the D suffix tells you it is a double row assembly. TDO and TDI indicate specific internal configurations. Always use the full part number when ordering a replacement.
You will find these bearings in mining equipment, cement plants, crushing plants, mills, conveyor belts, and agricultural machinery. They also appear in speed reducers and large transmission shafts where combined loads and harsh conditions are common. Their ability to take forces from both directions suits reversing rotation or alternating axial loads.
Selection depends on load magnitude and direction, speed, and the environment. Sealing keeps lubricant in and contaminants out; in dusty or humid areas, choose high-efficiency seals. Use the lubricant the manufacturer recommends, and align the mounting precisely to avoid parasitic stresses that shorten service life. Poor fitting leads to early failures.
Timken bearings can interchange with other well-known brands if standardized dimensions and tolerances match. When finding a replacement, check the complete part number and technical specifications, because small internal design differences can affect performance. MR Industrial Accessories can help you identify the right equivalent for your application.

Frequently asked questions
- What does the D suffix in the designation mean?
- The D suffix indicates a double row assembly, with two rows of tapered rollers in a single support. This allows it to withstand radial and axial loads in both directions, unlike single row bearings.
- How do I choose between a TDO and a TDI bearing?
- The TDO and TDI series differ in internal configuration and mounting method. The choice depends on available space, load type, and lubrication conditions. We recommend consulting our specialists to select the most suitable option.
- What should I take into account for mounting?
- Ensure precise alignment of the shafts, use the proper tools, and follow the manufacturer's instructions for fitting and lubrication. Incorrect mounting can cause premature failures and reduce bearing service life.
