MaalonDrive®

HighVac 8mm - 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® HighVac 8mm - type 1 micro positioning system was designed for use in high-vacuum environments, is lubricated with Fomblin and is characterised, in particular, by its compact design and high positioning resolution. The combination of a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 with an EC motor with rated voltage of 6V results in a precise, high-performance micro drive system. The gear is equipped with a preloaded ball bearing and an output shaft with application-specific design.
