Aerotech's new VTS300 vertical translation stages provide long travel precision positioning in a compact upright design for individual Z-axis payloads up to 450 kg, or may be arranged as multiple synchronised units that support heavy loads with kinematic 3-point mounting with the added potential for angled tip/tilt load manipulation. Available in a choice of four vertical travel ranges from 50 mm to 200 mm and with a base mounting footprint under 143 mm x 305 mm, the product series features a rigid, high stiffness aluminium frame with sealed linear motion guide bearings that allow heavy offset loads and provide excellent travel straightness and flatness. The high load capacity is also attributed to a precision ground lead-screw supported in a preloaded angular contact bearing arrangement that will not back-drive under load, thus guaranteeing complete stability in operation. With optional 23 or 34 frame NEMA motor mounting and with an integral high capacity 90° precision gearbox, both open loop stepper or servomotor drive technologies are available to match load, performance and budget requirements.
