RasuunDrive® BallScrew 10mm – Type 7
The RasuunDrive® BallScrew 10mm – type 7 provides an impressive travelrange of up to 10 mm. This is possible thanks to the combination of a DC Motor, an encoder with 256 Impulses per revolution and with a sturdy, low backlash CoograDrive® gear and a ball screw. The CoograDrive® gear comes with a reduction ratio of 80:1, directly integrated in the bearing of the gear output shaft is the ball screw with a pitch of 1 mm.
Benefits
1) Flexible integration
2) Preloaded ball bearing
3) Easy controllability
4) Ball screw
5) Transmission ratio optimized to torque
