Double Row TDIT Series71457TD Bearing

Double row tapered roller bearing TDIT is a double inner-ring bearing with a tapered bore.  It is comprised of a one-piece (double) inner ring and two  single outer rings. TDIT bearings are typically supplied complete with an  outer-ring spacer as a pre-set assembly. Contact your VAFEM engineer for spacer confifi guration information. These can be used in  fixed (locating) positions on rotating shaft applications. The tapered inner-ring bore allows for easy removal where  interference  fits are necessary and frequent removal of the  bearing from the shaft is desired.
