RasuunDrive® BallScrew 10mm - Type 2

RasuunDrive®

BallScrew 10mm - Type 2

Technical Supply Specifications

Features

  • High repeatability
  • Vacuum suitable lubrication
  • Ball screw
  • Preloaded ball bearing
  • Zero backlash at optimised fit between speed and resolution

Description

The RasuunDrive® BallScrew 10mm - type 2 combines a stepper motor which provides 20 steps per rotation, a MaalonDrive® gear and a ball screw. At its heart a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 can be found. Directly integrated in the bearing of the gear output shaft is the ball screw with a pitch of 1 mm. Thanks to this setup the linear actuator provides a travel range of 15 mm.
