MaalonDrive®

HighAcc 8mm - Type 3

Technical Supply Specifications

Features

  • High repeatability
  • Zero backlash with optimised fit between speed and resolution
  • Easy controllability
  • Preloaded ball bearing
  • Lifetime lubrication

Description

The MaalonDrive® HighAcc 8mm - type 3 micro positioning system is a very compact servo actuator. It combines a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 with an EC motor with rated voltage of 6V and integrated encoder with 64 pulses per rotation. Thanks to the preloaded ball bearings, the output shaft is precisely guided, thereby making it possible to directly connect the application.
