Lead Screws vs Ball Screws: It''s All about the Appliion | Helix …

The basic difference between lead screws vs ball screws is that a ball screw uses ball bearings to eliminate the friction between the nut and screw and lead screws do not. The screw and nut on a ball screw have matching helical grooves that allow ball bearings to re-circulate in those races, and are typically semi-circular in shape to accept the spherical ball bearing.
