RE: Ball screw
Ball screws are very accurate and repeatable, with little or no back lash, depending on the level of precision. As compared to an Acme screw, a ball screw has very little drive friction and can be back driven if necessary. This low friction will reduce the size of the motor required to drive the screw.
