Barnes Industries was founded in 1969. It is the first and only ball screw manufacturing plant devoted to reconditioning ball-bearing lead screws, and producing new ball screws with a warranty for all services. “Barnes” has grown from a one-man, 1000 sq. ft. shop to more than 50 people and an excess of 62,500 sq. ft. of floor space. The facility consists of 48,000 sq. ft. of environmentally controlled space devoted solely to manufacturing. The balance of space is used for engineering, sales, administration and accounting. Barnes 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).
