I once worked with Dynapert (tm) pick and place machines. The pick-up head slammed back and forth driven by the fact that the shaft that it slides on was rotating. The head connected to the shaft by a couple of sets of bearings clamped onto it. This was called a rholix drive. It worked like magic - very precise and no backlash.

Recirculating ball linear bearings ? They're the best. Oilite bushes also work, with slightly more free play. In both cases though the shaft they slide on has to be very parallel.

As always, it depends where you are. I got a good deal and good service from a company in the UK called

You'll have to lay down some figure for acceptable wiggle. Oilite bushes on ground shafts will work well for all but the highest precision work
