KeevoDrive® HighTemp 19mm – Type 1
The KeevoDrive® HighTemp 19mm – type 1 is especially well suited for applications in extreme environmental conditions – thanks to the dry lubrication and the materials that are used.
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 200 steps per rotation.
Based on an eccentric with ceramic ball bearings and an eccentricity of 3000 µm, a travel range of up to 6000 µm is possible.
At the heart of this dynamic and reliable micro system is a low-backlash CoograDrive® gear with a reduction ratio of 80:1.
Benefits
1) Suitable in wide temperature range
2) Dry lubrication due to coatings
3) Robust control without feedback system
4) High adjustment force
5) Step with in the range of nm
