The Double Row Metric Series tapered roller bearings in TDO (back-to-back) configuration provide bidirectional axial and radial load support from a single assembly. The opposing cone arrangement eliminates the need for separate thrust bearings while delivering exceptional rigidity. Essential for railway axle box assemblies, rolling mill roll necks, and heavy industrial gear reducers.
