Leadscrew Assemblies

Kerk® Leadscrews are available in standard diameters from 1/8" (3.2mm) to 15/16" (23mm), with standard leads from .012" to almost 4" (0.30mm to 92mm) including metric and left hand threads. Custom sizes and leads can be special ordered.  Most stock screws are manufactured from 303 stainless steel and are produced with Haydon Kerk's exclusive precision rolling process.  Other materials are available on special order.

Positional bi-directional repeatability (with the Kerk anti-backlash nut) is within 50 micro-inches (1.25 micron) and standard lead accuracy is better than 0.0006 in. /in. (mm/mm).  Lead accuracies are available to .0001 in./in. (mm/mm).

Haydon Kerk Motion Solutions™ has a wide variety of standard nut designs which offer many features to choose from.  Once an application’s most important requirements are understood, it becomes a matter of choosing the nut which best meets those requirements.  Occasionally, more than one nut might do the job, but in the vast majority of situations, one nut design will stand above the rest.  Patented anti-backlash designs, special purpose anti-backlash, general purpose, mini and custom design nuts are available.  All Kerk® nuts can be modified to some degree to help them better meet specific requirements.

Kerk® Leadscrew Assemblies are available in a broad range of screw sizes and nut styles, custom designed for your application.  They are self-adjusting, maintenance-free and require no lubrication. Providing maximum accuracy, high repeatability, smooth, quiet operation and low cost, Haydon Kerk Leadscrew Assemblies are your best choice for high performance linear motion control.

Kerk® brand anti-backlash nut and lead screw assemblies easily interface with many types of rotary power sources including stepper motors, servos, brushless DC, brush-type DC, and AC synchronous motors.  For optimum performance and accuracy, several patented anti-backlash designs are available, depending on application needs.
