I am using a very light version of this to drive tachs in my CNC system,
and they work fine. You should know that all the steel cable belts Berg
makes have SPLICES in them! If the splice is not made well, it can cause
a discontinuity in the reduction ratio, since there is a different pitch for
that one set of sprocket 'teeth'. The ones I've seen are quite well made,
however. But, that splice sort of always worried me for a combination
of power and positioning accuracy. If this is a spindle drive, the above
worries don't apply.
