I won't use helical beam couplings on anything. As said previously - they snap all too easily and if you have any backlash, they wind up and you may never get the full linear movement if there is any resistance. I snapped one on my router in less than 5 minutes and threw that and the other two in the scrap :) I too like Oldham couplings - I've made a few sleeves that fit the common coupling OD's - they make initial lining up easy for mounting motors or ballscrews. If the alignment is good they last many hundreds of hours too.
