Description

The MaalonDrive® UHV 8mm - type 2 micro gearbox is a precise and reliable solution for applications in extreme environmental conditions. It is specially designed for use in high-vacuum environments and uses Braycote as a lubricant for the ball bearings as well as for the gear component set. 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. At the core of this micro gearbox is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1.
