RasuunDrive® BallScrew 10mm – Type 28
The RasuunDrive® BallScrew 10mm – type 28 provides an impressive travelrange of up to 15 mm. This is possible thanks to the combination of a DC Motor and with a sturdy, low backlash CoograDrive® gear and a ball screw. The CoograDrive® gear comes with a reduction ratio of 40:1, directly integrated in the bearing of the gear output shaft is the ball screw with a pitch of 1 mm. The output bearing consists of two ball bearings, which are axially preloaded by springs with 21 N and are located between mechanical stops.
Additional agreed parameters:
Runout spindle nut 10 µm;
Runout spindle end 18 µm;
Motor current with built-in spindle nut 1,2 %;
Burn-in ball screw 1000 cycles.
Benefits
1) Flexible integration
2) Vacuum suitable lubrication
3) Easy controllability
4) High adjustment speed
5) Ball screw
