| 50 Ton Machine Screw Jack incorporates a machine cut lead screw in order to transfer rotational energy in to linear energy. The rotation of the worm screw acting on the lead screw via the worm wheel converts rotation in to linear motion. Available in a comprehensive range of materials and fittings with the option for special designs for specific application requirements. They are used in wide variety of automation applications including those in steel, automotive, communications, civil, defence, energy, glass and aerospace sectors. | |||||||||
