TIMKEN double row tapered roller bearings pack two rows of tapered rollers into one assembly. That layout lets them take radial and axial loads from either direction, which is why they turn up in gearboxes, transmission shafts and mining equipment. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.

The LL…EA code tells you what you are holding. The LL prefix points to a light-dimension series, and the EA suffix marks an internal execution built for higher load capacity and more even stress distribution. Part numbers such as LL428310EA and LL771911EA show how the letters and digits come together to define each size. The 2TS-DM series covers these double row assemblies with two cones and one cup, ready to mount where high rigidity is required.

On the floor, these bearings show up in mill and press gearboxes, cranes, road equipment, machine tool spindles and rolling mill rolls. Anywhere the shaft has to stay firmly positioned, such as final drives on agricultural machinery or conveyor belt reducers, their combined-load capability is the reason they are specified.

Selection starts with the radial and axial loads, the rotation speed and the space you have. These bearings do not tolerate angular misalignment, so mounting calls for careful alignment and precise axial adjustment. Grease or oil both work as lubrication, depending on the environment; in dusty or humid areas, pick seals suited to the conditions. Set internal clearance with shims or adjusting nuts, and follow the recommended tightening torque to avoid deformation.

When a replacement is needed, designations often get compared across manufacturers. Nomenclature differs from brand to brand, but the main dimensions and load capacity usually line up between equivalent products. Check that the code and measurements match the original, and use interchangeability tables. For TIMKEN, the 2TS-DM series is a common reference in double row applications. If you want an alternative, MR can point you to a compatible option.
