  • Zero backlash with optimised fit between speed and transmission ratio
  • Dry lubrication due to coatings
  • Preloaded ball bearing

Description

The MaalonDrive® Space 8mm - type 1 micro gearbox combines precision with reliability and extremely low weight. It is the ideal solution for applications in extreme environmental conditions and tight space conditions. Because ball bearings and gear component set are dry-lubricated, it can be used both in ultra-high-vacuum environments as well as at particularly low temperatures. Both the input shaft as well as the output shaft are precisely guided by preloaded ball bearings and thereby allow the application to be directly connected. A zero backlash MaalonDrive® gear with a reduction ratio of 160:1 forms the core of the gearbox.
