Kerk Motion Products, http://www.kerkmotion.com, one of the world's premier manufacturers of non-ball Custom Lead Screws, bridges the price/performance gap in Motion Contro l applications. With multiple benefits over traditional Ball Screws, including low cost and precision performance, Kerk's non-ball Custom Lead Screws create an exceptional value for designers and end users in a variety of industries.

  • Custom Lead Screws can be special ordered

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

  • Custom Lead Screws allow wider range of motion than traditional Ball Screws

Kerk offers Custom Lead Screws manufactured from 303 stainless steel, produced with Kerk's exclusive precision rolling process. Kerk's Custom Lead Screws provide reliable Motion Control and are available in standard diameters from 1/8" (3.2mm) to 15/16" (23mm), with standard leads from .02" to 3" (.5mm to 76mm). The anti-backlash nut allows positional bi-directional repeatability and a range unachievable with Ball Screws, including hard metric and left hand threads. Custom materials, sizes and leads are available upon request.
