MPS50SV and MPS75SV Miniature Mechanical-Bearing Screw-Driven Lift Stage


Design Features

  • Compact, high-performance elevation stage
  • Precision-ground ball screw or lead screw
  • DC or stepper motor options
  • High-vacuum capable
  • Precision crossed-roller bearings
  • Multi-axis configurations available with MPS linear and rotary stages
Aerotech’s MPS-SV series lift stages provide high-performance elevation motion in a compact, cost-effective design. Offered in two sizes (MPS50SV and MPS75SV), these lift stages are perfect for applications ranging from light-duty laboratory research to high-duty-cycle production processes. Multi-axis stage configurations can be assembled easily with other MPS linear and rotary stages using the multitude of adapter brackets and mounting compatibility inherent in the entire MPS stage family designs.

High-Accuracy Construction

All MPS-SV stages feature a precision-ground ball screw and preloaded crossed-roller bearings providing smooth and accurate geometric performance, exceptional accuracy and repeatability, and 0.05 µm minimum incremental motion capabilities. The MPS50SV is also offered with a lead-screw drive option for more cost-sensitive applications.

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

Vacuum and Mounting Options

As with all MPS-series stages, the MPS-SV stages are available in an optional 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 breadboard tables. The inherent mounting compatibility of all MPS stages allows for simple mounting in multi-axis arrangements.

Integration (Required)

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.

-TAS Integration - Test as system
Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
-TAC Integration - Test as components
Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
