    Using Precision Ball Screws In Medical Motion

    Sep 07, 2012 Although ball screws offer higher levels of precision, lead accuracy can vary across different models. The lead of the ball screw is the axial distance traveled when advancing the ball screw one revolution. Lead accuracy relates to the variation in distance traveled per revolution over the length of the stroke or shaft

    The “nut” uses recirculating ball bearings for extremely low friction and tight tolerances–little or no slop compared to an acme thread. Ballscrews are typically intended for CNC work, and so are made to minimize backlash. Because they turn with a lot less friction than an ACME screw, they can be built to much tighter tolerances

    Ball screws are screw drives that convert a rotating drive motion into a linear motion in normal operation. Due to the favorable friction conditions and the associated very high degree of efficiency ( 90%), they are in principle not self-braking so that in reverse operation a linear drive motion can also be implemented in the rotational direction
