ZeroBacklash 8mm - Type 1

Technical Supply Specifications

Features

  • Fast delivery
  • High repeatability
  • Zero backlash with high transmission ratio
  • Compact build up
  • Preloaded ball bearing

Description

Minimal outer dimensions and yet very high reduction ratio in a single stage characterise the MaalonDrive® ZeroBacklash 8mm - type 1 micro positioning gear. A zero-backlash MaalonDrive® gear component set with a reduction ratio of 500:1 forms the heart of this precise and high-performance gear. The gear component set is integrated in a gearbox with preloaded ball bearings on both the input shaft as well as the output shaft. As a result, they are guided precisely and the application can be directly connected.
