Double Row TDI SeriesLM287649D Bearing

Double row tapered roller bearing TDI style consists of a single-piece (double) inner ring plus two single outer rings. It is normally supplied complete with an outer-ring spacer as a pre-set assembly. To suit the application duty, the builtin setting value needs to be established by your VAFEM engineer before an order is placed. A groove and holes can be supplied in the outerring spacer to allow lubricant to pass from the bearing  housing. Contact your VAFEM engineer for spacer information.
