MaalonDrive®

HighAcc 8mm - Type 4

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 4 is an exceptionally compact servo actuator, consisting of a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 and an EC motor with rated voltage of 6V and integrated encoder with 128 pulses per rotation. The application can be directly and easily connected as the output shaft is precisely guided by preloaded ball bearings.
