New Barnes Ball ScrewsBarnes Industries, Inc. is the industry leader for best delivery of new precision ground, semi-precision, and commercial grade ball screws with internal or external ball return systems.  |  | | | | This is accomplished by proven manufacturing processes, rigid quality control, and an extensive inventory of induction hardened and ground shafting. Screw material is always on hand for all common English and metric sizes between 1/2 inch and 6 inch (12 mm to 150 mm) diameter with lengths through 40 feet, (12 meters). For Screw diameters larger than 6 inch, consult our sales department. Longer lengths can be manufactured by permanently joining bars by a special process to achieve screw lengths up to 70 feet (21 meters). | | |  |  | | | | Barnes New Ball Screws are manufactured to high quality standards, which meet or exceed all industry standards including, ANSI, ISO, DIN, and JAS. Close control of thread form radius and lead provide increased load carrying capacity and longer wear life. We offer engineering assistance for new ball screw designs and for improving existing applications, including conversions and retrofits from acme screws to ball screws. Our engineering department will work with machine tool manufacturers seeking to improve machine designs or make custom ball screws for special applications. |
