LAR - Series with Linear Rotary Motion

The vacuum-built-in shaft through the rotary motor is available for some models to prevent dust build-up in the unit. These z-theta actuators can easily be programmed to control force/torque, position and velocity in all axes at the same time with feedback capability. SMAC's unique, patented "Soft-Land" function enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator.

  • Soft-Land function and precise force/torque control
  • Precision Positioning
  • Vacuum built-in through the shaft
  • Safety return spring option available
  • Data Feedback
