MaalonDrive® UHV 14mm - Type 1

MaalonDrive®

UHV 14mm - Type 1

Technical Supply Specifications

Features

  • High repeatability
  • Vacuum suitable lubrication
  • Zero backlash with optimised fit between speed and resolution
  • Easy controllability
  • Preloaded ball bearing

Description

The MaalonDrive® UHV 10mm - type 6 micro positioning system, designed for applications in ultra-high-vacuum environments and therefore lubricated with Fomblin, is characterised by its extremely short length. The combination of a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 with a flat EC motor with rated voltage of 6V results in a high-performance and space-optimised micro positioning system. Preloaded ball bearings mounted on the output side allow the application to be directly connected.
