Ball Screw Manufacturing

ball screw manufacturingBarnes Industries, Inc. is the industry leader for high quality and fastest delivery of new replacement precision ground, semi-precision and commercial grade ball screws.

Most new ball screw assemblies manufactured by Barnes are delivered in 5-7 weeks or sooner if expedited. Just submit a drawing or sketch of your screw, or send in a sample ball screw assembly and we will begin the quoting process immediately on a high quality unit that will fit as a direct replacement in your machine tool.

Custom Ball Screw Manufacturing

Barnes Industries manufactures new ball screws faster than anyone in the ball screw industry. We have even made 6” diameter x 40 foot long ball screw assemblies in only 6 weeks. This is accomplished by proven manufacturing processes, rigid quality control, and an extensive inventory of induction hardened and precision ground alloy steel shafting that is ready for processing.

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 52 feet (15.8 meters).

Barnes New Ball Screws are manufactured to high quality standards, which meet or exceed all industry standards including ANSI, ISO, DIN, and JAS (ISO 3408 and DIN 69051). Close control of thread form radius and lead provide increased load carrying capacity and longer wear life.
