Description

Dry lubrication, compact outer dimensions and low weight - the KeevoDrive® Space 10mm - type 2. Thanks to the dry lubrication and the materials that are used, this micro positioning system is especially well suited for applications in extreme environmental conditions. Whether in ultra-high-vacuum environments or at extreme temperatures, the positioning unit can be reliably and easily operated in an open loop control thanks to its stepper motor with 20 steps per rotation. The system has an eccentricity of 1000 µm, thereby making possible a travel range of up to 2000 µm. At the heart of this precise and reliable micro system is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1.
