What started as a family business in the basement of the McBain home grew to a successful leader in the ball screw industry. It has continued to grow and thrive with Linda McGary (McBain) serving as president since 2006.

The ball screw assembly consists of a screw and a nut, each with matching helical grooves The balls roll between these grooves providing contact between the nut and the screw. These re-circulating bearings allow the unit to operate at an extremely high rate of efficiency with excellent static and dynamic load ratings.
