MaalonDrive® HighAcc 8mm - Type 6

MaalonDrive®

HighAcc 8mm - Type 6

Technical Supply Specifications

Features

  • High repeatability
  • Zero backlash at high speed
  • Robust control without feedback system
  • Preloaded ball bearing
  • Lifetime lubrication

Description

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.
