Kerk's Screws Bridge Price/Performance Gap for Motion Control



Low cost, precision non-ball lead screws create exceptional value

Kerk Motion Products, one of the world's premier manufacturers of non-ball lead screws, bridges the price/performance gap in motion control applications. With multiple benefits, including low cost and precision performance, Kerk's non-ball lead screws create an exceptional value for designers and end users in a variety of industries.

For vertical applications, Kerk's non-ball lead screws can be designed to self-lock and prevent back driving, without an external brake, unlike traditional ball screws. Utilizing sliding friction between the nut and the screw to convert rotary input motion to linear output motion, Kerk's non-ball lead screws offer accuracy comparable to ground ball screws, at a cost savings up to 90%. Because the screws do not need to be hardened, they are more easily machined, contributing to overall low product cost. Kerk's lead screws are manufactured with a proprietary coating, which eliminates the need for external lubrication and maintenance. Additionally, Kerk's screws provide quiet, reliable operation, with design flexibility.

Kerk offers lead screws manufactured from 303 stainless steel, produced with Kerk's exclusive precision rolling process. They are available in standard diameters from 1/8" (3.2mm) to 15/16" (23mm), with standard leads from .02" to 3" (.5mm to 76mm), a range unachievable with ball screws, including hard metric and left hand threads. Custom materials, sizes and leads are available upon request.
