LAR Series Linear Rotary Actuators

LAR Series

The precision Z-theta motion within one small actuator, providing a convenient pick, orient and place. A wide variety of linear rotary actuators are offered with either direct drive or gearbox equipped rotary units.

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.

Return spring: Prevents the shaft from dropping during vertical operation when power is cut.

Vacuum: For pick and place applications

Extended nose bushing: For tighter shaft run-out and higher side load onto the shaft.

Increase of max. force and acceleration: 48 volt coil and double coil options are available for some units with 24 volt single coil.

Increase of torque/gear ratio: Alternative geared motors are available for some units.

Rotary encoder resolution: Consult factory for higher resolution.

Increase of force accuracy & lifetime: Extra long life linear guide, Low friction linear guide
