# RasuunDrive® BallScrew 10mm – Type 12

The RasuunDrive® BallScrew 10mm – type 12 provides an impressive travelrange of up to 15 mm. This is possible thanks to the combination of a EC Motor, an encoder with 1024 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
