Double Row TDO Series=M1181 Bearing

Double row tapered roller bearing TDO consists of a single-piece (double)  outer ring and two single inner rings.  This confifi guration offers a wide  effective bearing spread to support  loads created by overturning moments. These bearings can be used at  fixed  positions or allowed to float in the housing  bore to compensate for shaft expansion.


Double row tapered roller bearing TDO bearings are usually supplied complete with an inner-ring  spacer as a pre-set assembly.   To suit the application duty, the built-in setting value needs to be  established by your VAFEM engineer before an order is placed. For spacer confifi guration information, contact your Timken  engineer. Double outer ring can be used with any single inner ring from  the same series. The tables list regularly specififi ed inner-ring part numbers.
