An actuating assembly for moving an operative member of a glassware forming machine, the assembly comprising a connecting casing adapted to be fixed to a supporting structure of the machine;

• a shaft supporting the operative member and coupled to said connecting casing so as to translate and rotate about a fixed axis thereof;
• a pneumatic jack for displacing said shaft along said axis and comprising a rod connected to said shaft and a piston;
• a cam and tappet device for rotating the shaft in opposite directions about said axis;
• the device comprising a chamber and a cam and tappet assembly housed in said chamber and lubricated by a lubricating fluid present in said chamber;
• and hydraulic means for stabilizing the motion of said supporting shaft and comprising an operative fluid;
• characterized in that said chamber and said stabilization hydraulic means define part of a single closed hydraulic circuit for flowing a lubricating and operative fluid which is in common to said cam and tappet device and to said stabilization hydraulic means.
