TDO (Two-Row Double-Outer Race) The configuration of the TDO provides a wide effective bearing spread, making it ideal for applications in which overturning moments are a significant load component. TDO bearings can be used in fixed positions or allowed to float in the housing bore.

 For information on selecting the appropriate bearing for a given application.For general information on rolling bearings, refer to General bearing knowledge.Double row tapered roller bearings SKF manufactures double row tapered roller bearings in the TDO  and TDI designs, in many variants and with different features. Depending on the design, these bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.
