MaalonDrive® HighAcc 8mm – Type 6
Zero backlash, high dynamics combined with low outer dimensions – the MaalonDrive® HighAcc 8mm – type 6.
Through the combination of a zero-backlash MaalonDrive® gear with a reduction ratio of 120:1 with a stepper motor with 20 steps per rotation, the positioning system can easily be operated in an open loop control.
Thanks to the preloaded output-side ball bearings, the application can be directly connected to the micro actuator.
Benefits
1) High repeatability
2) Lifetime lubrication
3) Preloaded ball bearing
4) Robust control without feedback system
5) Zero backlash at high speed
