Abstract

Improved pulley for metal rolling doors, characterized by being formed by two metal sheets, each of them defining a circular area bent in a surrounding flange, and finding the circular areas juxtaposed by their external faces, leaving the eyelashes oriented in opposite directions, for offering a cylindrical surface on which the winding of the door is carried out, and both circular areas having a central hole, which are orthogonally crossed by a tubular section, in which at least one extra hard plastic sleeve is housed, which acts as a friction bearing on which the shaft on which the rotation of the pulley is engaged, and being attached to at least one of the circular areas, a plate disposed radially from the tubular section to the corresponding flange, and providing for the minus two through holes that interest the two circular zones and the plates, and being fir means, preferably by welding, the assembly formed by the two plates, the tubular section and the plates.
