High-Performance Screw-Jacks offer precise linear positioning and high dynamic performance by means of a servo-worm reducer and precision ballscrew spindle. Linear speeds up to 590 inches per minute can be achieved with ballscrew diameters up to 50 mm and axial load capacities up to 22,500 lb. For higher load capacities, two screw-jacks can be used in tandem to share the loads.
These screw-jacks are available in four sizes with rotating ballscrews and translating nut, or lifting cylinder design. Both designs can be used with 100% duty cycles. The ballscrew spindles are protected against contamination by bellows or protective tubes and are continuously lubricated with an automatic lubrication system.
Applications requiring precise, controlled linear motion with high dynamic performance are perfect for these drives. Typical applications include sheet metal bending, hydraulic cylinder replacements, conveyor tensioning, and lifting table drives. Industries served include Material Handling, Automation and Automotive.
