Tandem thrust tapered roller bearing with shaft

The invention relates to a tandem thrust tapered roller bearing with a shaft. The tandem thrust tapered roller bearing comprises shaft rings (010), seat rings (020), outer space rings (030), single-stage thrust tapered rollers (040), inner space rings (050), stepped shafts (060) and positioning screw rods (070). Multiple single-stage thrust tapered roller bearings are arranged on the stepped shaft in series, positioning screws are screwed, a positioning hole (021) in the seat ring of the last single-stage thrust tapered roller bearing and a positioning hole (062) of the stepped shaft are positioned, positioning of the stepped shaft and a tandem bearing pack is ensured, and therefore the tandem tapered roller bearing with the shaft is formed and is high in bearing capacity. The bearing is scientific and reasonable in design, creative, high in economic applicability, stable and reliable, the bearing assembling precision and the bearing performance are guaranteed, and the service life is prolonged. 本发明是一种带轴的串联推力
