Kerk’s products have been designed specifically for motion control applications. They are not compromised adaptations of general purpose screws or nuts. Our Lead Screw Assemblies, Slides and Actuators, Splines and Linear Guides are all designed for high performance, maximum life, quiet operation, and cost-effectiveness. They also deliver the advantage of Kerk’s innovative anti-backlash technology and proprietary Kerkote® TFE coating.

Self-adjusting, maintenance - free, requiring no lubrication, Kerk Lead Screw Assemblies deliver high performance linear motion control at a low cost. Available in a broad range of screw sizes and in anti-backlash, general purpose, special purpose and mini nut styles, they can be custom designed to your special application.
