  • Enerpac machine screw actuators are self locking. No cribbing required when actuator is subjected to minimal vibration
  • Precision Rolled Acme Thread allows positioning within thousandths of an inch
  • Hardened Gear Set allows higher efficiency and longer life
  • Precision Gears allow synchronized lifting in multi-actuator systems
  • Rugged housings made of Cast Aluminum Alloy (MA models) or Ductile Iron to safely mount to a variety of structures
