Precision lead screws and customised nut designs

11 December 2009

Haydon Kerk Motion Solutions is offering precision lead screws and customised nut designs for motion control applications where ball screws may have been originally considered.
For vertical applications, Kerk lead screws can be designed to self-lock and prevent back driving, unlike traditional ball screws.  Utilising a sliding motion between the nut and the screw to convert rotary input to linear output motion, the Kerk non-ball lead screws offer accuracy comparable to ground ball screws.

Kerk lead screws are manufactured with a choice of proprietary coatings, depending on the application requirements.  Kerkote and Black Ice dry lubrication coatings eliminate the need for external lubrication and maintenance. Application-specific nut features can also be customised using Kerkite high performance polymers or various customer-specified specialty materials.

Manufactured from 303 stainless steel, Kerk lead screws are available in standard diameters from 1/8in (3.2mm) to 15/16in (23mm), with standard leads from .02in to 3in (.5mm to 76mm).
