Description:

PSAV series motorized vertical-motion stages employ ball screw reducers to ensure ultra-high loading capability. The backlash clearance of ball screws reducers is much smaller than that of trapezoidal reducers and it is helpful to provide higher motion accuracy and positioning accuracy. The smooth running is guaranteed by using selected aluminum alloy and four pieces of linear bearing guides. A wider travel range of 50-400mm is offered by this series products which can meet most of customers' requirements. This is a series of motorized verticalmotion stages to be suitable for the applications which need higher loading capability and longer travel range in optical experiments, fine positioning and fine processing.
Main characteristics:

•Longer travel range and higher loading capability are guaranteed by using ball screw reducers

•Four pieces of linear bearing guides constitute guiding mechanism to ensure high motion accuracy and smooth running

•Long travel range is up to 400mm

•Reliable standard two-phase 57 stepping motors have characteristics of high torque and high loading capability
