Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks. Mechanical capacity of screw jacks is between 5kN and 2000kN. Jack screws can be used as linear motors, linear actuators, or mechanical lifts depending on type of motion.
ACME Machine Screw Jacks Features
•Are best for slower movement and low to moderate duty cycles•Most machine screw jacks are inherently self-locking in the absence of vibration
•A brake motor is usually NOT required to hold position on self-locking jacks
•Anti-backlash devices can be specified to limit backlash in reversing loads•Stainless steel, metric, and motorized jack models are available with machine screws
•Adaptable for wash down applications
