Components for vacuum applications


Important differences to other kinds of system and plants have to be taken into consideration when using drives and moving components in vacuum chambers. Many components are no standardized catalogue products and have to be custom-built.


LSA GmbH disposes of manifold references and is able to rely on a huge experience base for the construction and realization of vacuum compatible actuator systems. During a variety of successful projects expertise for drive systems in technical vacuum and in clean rooms was acquired. We use special materials with respect to gas rates and particle emissions (i.e. VA stainless steel, non eloxed aluminium, PEEK). With carefully selected modules, solutions under extreme conditions were realized.


clean room

Vacuum compatible systems are built up at LSA GmbH in a special clean room with high cleanliness requirements and minimal risk of contamination for the components to be assembled. The systems will be delivered after functional tests. Our specialty are high dynamic systems with long range, high velocities and extreme accelerations with µm precision in small installation space.


The load reaches from grams to several 100 kg. After the development of many special solutions for customer requirements we draw on a broad portfolio of successfully applied linear and rotary actuators. So already a travel length of 6 m was realized and permanent accelerations of 10 m/sand more are common.


We plan and install individual actuators as well as complete positioning systems with several axes that are geared to each other.


In development of high- and ultrahigh-vacuum systems we have recourse to a wide-ranging pool of specialized suppliers. In addition we are able to construct and manufacture special components in accordance with your requirements.

Vacuum linear drive:


The linear axis is a further development of our own modular drive system. The experiences made in a variety of pervious solutions were incorporated in the development. The drive is conditioned for use in a technical high vacuum down to 10-7 mbar. The motor is designed brushless and iron-free. The axis is freely scalable up to a length of several meters. The cross section can either be executed as highly loadable profile (2 guide rails, centered magnet track) or in compact design (1 guide rail, magnet track above).


  • Suitable for precise movement of very high payloads (up to 1,000 kg)
  • 0,01 – 5,000 mm/s
  • Up to 50 m/s²
  • Up to 0.001 mm repeatability
  • Up to 0.003 mm positioning accuracy


With our modular construction system a lot of customer-specific versions can be drawn, modeled, manufactured and applied quickly.
