RasuunDrive® BallScrew 10mm – Type 2
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.
Benefits
1) High repeatability
2) Vacuum suitable lubrication
3) Preloaded ball bearing
4) Zero backlash at optimised fit between speed and resolution
5) Ball screw
