Lift stages


Aerotech's MPS-SV series lift stages provide high-performance elevation motion in a compact, cost-effective design. These lift stages are engineered for applications ranging from laboratory research to high-reliability production processes and are offered in two sizes - the MPS50SV and MPS75SV. The multitude of adapter brackets and mounting compatibility inherent in all MPS stages permit easy assembly of multi-axis configurations using linear, rotary and lift MPS stages.

High-Accuracy Construction
MPS-SV stages utilize a precision-ground ball screw and preloaded crossed-roller bearings for smooth and accurate geometric performance, exceptional accuracy and repeatability, and 0.05 µm minimum incremental motion. The MPS50SV is also offered with a lead-screw for more cost-sensitive applications. Unlike competitive products that use belts and other high-wear-rate components, all drive train mechanics are designed with high reliability and service life in mind.

MPS-SV motor options include a DC servomotor with rotary encoder and a stepper motor. A precision-machined wedge design and lateral constraint system result in high stiffness and load capacity, while at the same time providing constraint of lateral motions.

Vacuum and Mounting Options
As with all MPS-series stages, the MPS-SV stages are available with vacuum preparation to 10-6 Torr that includes a vacuum-rated connector. An optional mounting plate provides direct mounting to both English and metric optical breadboards. The inherent mounting compatibility of all MPS stages allows for simple mounting in multi-axis arrangements.
