M-Series, Machine Screw Actuators

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
