The TIMKEN TDO series double-row tapered roller bearing is an assembly that integrates two rows of tapered rollers in a single unit, with cones and cup joined. It is used to support combined radial and axial loads in both directions, with high load capacity in reduced spaces. It is common in applications requiring rigidity and precision, such as gearboxes, machine tool spindles and mining equipment. MR Accesorios Industriales sells it in Buenos Aires, Argentina.
The TDO series designation is made up of two codes: the cone and the cup. In the examples, the cone and cup codes are combined according to the reference; the double cup is identified with the D suffix. The initial letter M indicates a metric tapered roller series; the D suffix on the cup indicates it is a double cup, that is, two raceways in a single piece. This nomenclature allows ordering the complete assembly or each component separately, always respecting the cone-cup combination that defines the mounting.
In Argentine industry, TIMKEN TDO series bearings are found in demanding applications: mill gearboxes, jaw crushers, presses, cranes and railway equipment. They also appear in machine tool spindles and rolling mill rolls. Their ability to support combined loads and their rigidity make them suitable for assemblies where the shaft must be perfectly guided, with little deflection and high repeatability. They are common in cement, steel and oilseed plants.
To select a TDO bearing, take into account the radial and axial load it must support, the rotation speed and the available space. Mounting requires correctly aligning the assembly and applying the appropriate preload according to the manufacturer. Lubrication can be grease or oil, and sealing must be chosen according to the environment: dust, water or high temperatures. The double cup allows simpler axial adjustment than two separate bearings, but requires verifying internal clearance after mounting.
TIMKEN tapered roller bearings are interchangeable with those of other brands under the same standardized designations, although tolerances and capacities may vary. When requesting a quote, it is advisable to indicate the complete cone and cup code, or the assembly number if known.

Frequently Asked Questions
- What does the M…D designation mean in TIMKEN bearings?
- The letter M indicates a metric tapered roller series. The D suffix on the cup indicates it is a double cup, with two raceways in a single piece. The complete code combines a cone and a double cup, according to the specific reference.
- How do I choose between a TDO bearing and two single bearings?
- The TDO integrates two rows in a single assembly, which simplifies mounting and reduces axial space. If you need greater load capacity or rigidity, the TDO is usually the option. For lower loads or simpler assemblies, two single bearings may be sufficient.
- What lubricant is suitable for a double-row tapered bearing?
- It depends on the speed and working temperature. For general applications, high-pressure lithium grease; at high speeds or temperatures, circulating oil. Always follow the equipment manufacturer's recommendations and verify sealing to prevent contamination.
