Electromechanical jack, essentially characterized by being constituted from a support body endowed with two lateral stages in one of which is coupled an electric motor, preferably of low voltage, whose axis carries a sinfin, encasquillado to the support body and whose sinfºn acts on a gear ring keyed to a rotating shaft supported on a bearing, it being provided that the lateral surface of said shaft is traversed by a helical rib that is complementary with a thread provided on the inner surface of a hollow rod, coaxial, with the cited tree, and capable of effecting vertical displacement, emerging from the support body, by turning the worm, all with the particularity that the base of the support body is equipped. Of a threaded cap that internally has a circular stagger for the storage of grease while externally has a series of notches arranged equidistantly for the reception of a tightening tool, there also being a conduit that is born on the outside of the support body, from a plug or grease valve ends in the bearing area of the shaft.
