MaalonDrive® ZeroBacklash 8mm - Type 4

MaalonDrive®

ZeroBacklash 8mm - Type 4

Technical Supply Specifications

Features

  • High repeatability
  • Zero backlash with optimised fit between speed and resolution
  • Preloaded ball bearing
  • Lifetime lubrication
  • Use of high quality materials

Description

Zero backlash combined with dynamics and yet small outer dimensions characterise the MaalonDrive® ZeroBacklash 8mm - type 4. The combination of a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 with a DC motor with rated voltage of 3V results in a high-performance micro actuator. The output shaft is precisely guided by preloaded ball bearings which allow the application to be directly connected.
