RasuunDrive® BallScrew 26mm – Type 3
The linear actuator RasuunDrive® BallScrew 26mm – Type 3 is suitable for very precise positioning applications and offers a maximum travel range of 52 mm. The actuator consists of a powerful stepper motor, a backlash-free high-reduction-ratio HarmonicDrive gear HFUC-5 and a low-friction ball screw with a diameter of 12mm. Heart of the system is the robust and backlash-free Harmonic Drive® gear with a gear ratio of 100:1. With its 200 steps per revolution offers motor enough resolution for positioning in the sub-micrometer range. The powerful and backlash-free ball screw with a pitch of 2 mm is directly integrated into the axial, highly rigid bearing of the gearbox output.
Benefits
1) High axial load capacity
2) Easy controllability
3) Extreme power density
4) Zero backlash with high transmission ratio
5) Step with in the range of nm
