Ball screw drive RM...-FK

Ball screw with FK nut

Ball screws, also known as ball screws or ball screws, are used in a variety of ways in almost all areas of industry. They serve to convert a rotational movement into a longitudinal movement. Between the spindle, more precisely the threaded spindle, and the nut, the balls roll in an endless loop via a ball feedback system and thus guarantee the smooth movement of your application. The spindle is available in rolled, whirled and ground. The manufacturing process has an impact on price and accuracy.
