Power Jacks offers E-Series screw jacks. The design features a precision worm gear set, powerful lead screw, robust housing, two integrated lubrication mechanisms and a comprehensive range of options.
The basic unit is designed to allow fitment of one of the three main lead screw types of machine screw, ball screw or planetary roller screw. Each of these types is available in translating or rotating screw configuration. From this point the number of possible variants grows exponentially to meet customer solutions and include anti-backlash, anti-rotation, safety nut, motor drive, limit switches and even a complete stainless steel version. The screw jacks are installed singularly or as part of multi-unit jacking systems. Since the E-Series range of screw jacks extends to a design with a nominal capacity of up to 3500 kN, the potential actuation force of a jacking system is massive.
In addition to these standard variants, Power Jacks’ engineering team can provide fully customised products and solutions. “This classic single face screw jack is one of the most widely used and popular screw jacks worldwide,” says Bruce Hamper, Customer Service and Marketing Director with Power Jacks in Fraserburgh, Scotland. “It has proven its capability in the most demanding linear motion applications whether as a standard design or a customised solution.” E-Series screw jacks catalogues, maintenance manuals, 2D drawings and 3D CAD models can be downloaded at Power Jacks’ website at www.powerjacks.com.
