MaalonDrive® HighAcc 8mm - Type 1

MaalonDrive® HighAcc 8mm – Type 1

The MaalonDrive® HighAcc 8mm – type 1 micro servo actuator is driven by a DC motor with rated voltage of 12V and integrated encoder with a resolution of 100 pulses per rotation.
Exceptionally dynamic and yet absolutely reliable, the micro positioning system is equipped with a zero-backlash MaalonDrive® gear with reduction ratio of 160:1.
By means of the preloaded ball bearings on the output shaft, the customer application can be directly connected.

Benefits

1) High repeatability
2) Lifetime lubrication
3) Preloaded ball bearing
4) Easy controllability
5) Zero backlash with optimised fit between speed and resolution
