About Rockford Ball Screw

Ian McBain founded Rockford Ball Screw in 1973 utilizing his years of experience in the industry with the goals of providing a quality product, on-time and at a competitive price. 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.

In 2009, Rockford Ball Screw added linear guide rails and blocks to its product range. Rockford Linear Motion compliments its product line with another linear motion tool. The high-performance product is provided with extremely short lead times, making it a perfect fit for RBS's customers.

Today, Rockford Ball Screw (RBS) is the industry leader in Ball Screws and Linear Guide Rails and continues to serve its customers with a state-of-the-art facility, providing personalized customer service every step of the way. It offers an extensive product family, and one of the largest inventories of ball screw and ACME screw product lines in the industry, including catalogued, non-catalogued, standard, and non-standard offerings. Innovative engineering expertise and state-of-the-art manufacturing processes ensure top performance and reliability in all its products.
