TIMKEN 2TS-DM double-row tapered roller bearings are pre-assembled units that house two rows of tapered rollers within one envelope. The cones and cups are matched as a set at the factory. They suit applications where heavy radial and axial loads act in both directions, rigidity is critical, and mounting space is tight, such as gearboxes, off-road machinery shafts, and transmission systems.

The part number breaks down into two main blocks: the cone designation first, then the cup, separated by a hyphen. In the 2TS-DM series, digits after the Y denote internal design variations, including contact angle or corner radius, while the final S points to the seal type or assembly arrangement. Examples like 88900Y1S-88126 and 96900Y5S-96140 are cone-cup pairs that Timken classifies under this series for double-row duty.

In industrial settings, these bearings are common in gearboxes for mills, presses, cranes, and road equipment. They also appear in machine tool spindles and heavy conveyor rolls, where the double row handles combined loads without extra components. As matched assemblies, they streamline installation and provide a fixed internal clearance from the factory, cutting down on-site adjustment and boosting repeatability across machinery.

When selecting a replacement, check the cone and cup diameters, overall assembly width, and sealing method. The 2TS-DM series supports various lubrication setups: grease for moderate speeds or circulating oil for tougher conditions. Proper alignment of both rows and adherence to the lock nut torque are essential; too much preload reduces service life, while excessive clearance leads to vibration and uneven wear.

TIMKEN double-row bearings can interchange with other brands that offer similar assemblies, as long as key dimensions, contact angle, and internal clearance align. A similar part number alone is insufficient; you must verify the full cone and cup designation, since minor differences in radii or surface treatment affect load behavior. If unsure, provide the original part number and we will identify a compatible alternative.
