Servo Spec gearbox's ---- Any offer considered

[Jonathan]

You have an interesting point on the back lash, when i used one of these it was with back lash compensation, once i had set it up i never had to adjust it - it seemed very consistent.

I see, that's promising. The problem for me is that backlash compensations does not help with the play caused by the backlash. For a rotary axis used with a router or milling machine I think no play is a requirement, otherwise the cutter may vibrate relative to the work-piece? I think is especially true if it's used to rotate the spindle itself, which is my intention. Say there's 100mm from the axis of rotation to the cutter tip, with 19arcmin that's quite a lot of movement: pi*100*19/60/360=0.28mm.

What is the motor input shaft diameter for each of them?

The PLE is the perfect economy alternative to the PLN. We have specifi cally
designed this planetary gear for all applications in which a particularly low backlash
is not necessarily the main focus.

No idea really what to offer you for them. I'm probably only interested in the 25:1.
