Timken double row tapered roller bearings are self-contained assemblies that use two rows of tapered rollers to handle radial and axial loads in both directions. They are common in gearboxes, drive shafts and mining equipment, where high load capacity and rigidity are required. MR Industrial Accessories LLC supplies this line to customers across the United States, Canada, Mexico and South America.

The part numbering follows a series-based logic. The TDO series covers double row assemblies with two cones and a common cup, and it includes references such as HM120848, HM227519 and HM321245. Letter prefixes like HM or HH point to dimensional and capacity families, while the digits that follow define the size. The 2TS-IM and 2TS-DM series are double row versions built for particular mounting arrangements. If a code is unclear, the MR technical team can help you read it.

These bearings appear in demanding industrial settings: mill gearboxes, presses, cranes, road and railway equipment, oil industry machinery, support rollers for kilns and construction machinery. The double row layout supports high radial loads and axial loads in both directions, which can reduce the need for extra bearings.

When selecting a bearing, review the radial and axial load, the rotation speed and the operating environment. Sealing matters: in dusty or damp conditions, sealed configurations are the better choice. Follow the manufacturer's lubrication instructions and align the mounting precisely to avoid unnecessary stress. Poor adjustment can shorten bearing life. The MR team can assist with the selection.

On interchangeability, Timken bearings can be replaced with equivalents from other recognized brands, but dimensions and load capacities must be checked. Not every code swaps directly, and the mounting may need adjustment. Consult a specialist before substituting a bearing from a different brand. MR Industrial Accessories LLC supplies the Timken line and can guide you toward a suitable alternative for your equipment.
