MaalonDrive® SpecialShaft 10mm – Type 7
The MaalonDrive® SpecialShaft 10mm – type 7 micro positioning system is characterised by an application-specific geometry of the output shaft and, as a result, can be optimally integrated in the application.
The combination of a zero-backlash and high-reduction MaalonDrive® gear with a reduction ratio of 120:1 with an EC motor with rated voltage of 6V and an integrated encoder with a resolution of 4096 pulses per rotation results in a high-performance micro positioning system.
Preloaded ball bearings are mounted on the output side, allowing the application to be directly connected.
Benefits
1) Vacuum suitable lubrication
2) Preloaded ball bearing
3) Easy controllability
4) Custom designed output shaft
5) Zero backlash at high adjustment speed
