Rockford Ball Screw

Rockford Ball Screw offers innovative motion solutions built on the highest performance design standards with one of the largest inventories of Ball Screw, ACME Screw and Linear Guide Rail product lines in the industry - and continually growing. Our extensive product line includes both standard and custom-designed solutions.

It's Your Move


RBS' Flagship product, the ball screw, is a mechanical linear actuator and consists of a screw that runs on ball bearings. Matching helical grooves on the screw and nut recirculate the bearings, making it an efficient way to convert angular-to-linear motion and vice versa. They are made to close tolerances making them suitable for situations demanding high precision.

Rockford Ball Screw also provides one of the most complete line of free-wheeling ball screw assemblies, preloaded ball nuts, ACME screw products and standard bearing mounts in the industry.



Rockford Ball Screw provides the linear guide rail solutions that are embedded into the machines we use daily or that build the products we depend on to lead our lives. Our Profile Guide Rails provide accurate, stable, and smooth linear guidance under a wide range of speeds, loads, conditions and space requirements.

Both Standard Profile and Low-Profile series of blocks are available with or without a flange and in a standard or low-profile height. Blocks are available in multiple sizes and lengths to suit our customer's application.
