Key features

  • Ultra-stiff construction for minimal deflection
  • High cantilevered load capacity
  • Ball screw drive mechanism with recirculating linear slides
  • Bellows with 50,000 cycles guaranteed as standard (1 million option)
  • 1mrad deflection under vacuum load
Show me more key features

This customisation can include meeting the required flange size, stroke, bore size, duty cycle and space envelope. In addition, any required sensors, motors and encoders can be incorporated and pre-wired for plug & play operation.

All production LSMs benefit from:

  • Ultra-stiff construction for minimal deflection
  • High cantilevered load capacity
  • Ball screw drive mechanism with recirculating linear slides
  • Bellows with greater than 50,000 cycles guaranteed with option for 1 million cycles

Our in-house manufacturing facility enables us to cost-effectively and rapidly produce highly toleranced, high quality components. Components are cleaned prior to assembly in an ISO 7 Class 10,000 clean room.
