KERK® WGS® LINEAR SLIDE    

Click here for Motorized WGS Linear Slide          

   

 

Made of the same quality components used in the RGS® series, the Kerk® WGS Linear Slide utilizes a screw-driven carriage that offers reliable, continuous linear speed while maintaining accurate positioning.  The length and speed of the WGS is not limited by critical screw speed, allowing high RPM, linear speed and long stroke lengths.  The WGS slide has a unique, compact profile that provides improved torsional stiffness and stability over RGS and RGW products.  The integral mounting base can provide support over the entire length that can extend up to 8 feet (2.4 meters).  Longer lengths are possible on a special order basis. 

Standard leads include .100-in, .200-in, .500-in and 1.00-in (2.54, 5.08, 12.7 and 25.4 mm) travel per revolution.  Many optional leads, both inch and metric based, offer everything from high efficiency to non-backdriving leads for vertical applications, eliminating the need for brakes. With Haydon Kerk Motion Solutions, Inc. wide range of available leads, speeds of more than 60 inches per second (1.5 meters per second) are possible, rivaling belts and cables while offering superior positioning accuracy, repeatability and axial stiffness. 

The WGS utilizes sliding plane bearings on a low profile aluminum guide rail that keeps the motion smooth throughout the travel distance. The lead-screw is precision-made of high-quality stainless steel rolled on-site at our U.S. manufacturing facility.  All moving surfaces include Kerkite® high performance polymers running on Kerkote® TFE coating. 

The slides come with a wear-compensating, anti-backlash driven carriage.  Additional driven or passive carriages can be added, along with application specific customization.  Linear guides, without the drive screw, are also available.

 The Wide Guide Screw utilizes sliding plane bearings on a dove-tailed aluminum guide rail.  The plane bearings, made of Kerkite high performance polymers, act as gibs securely mating the carriage to the Kerkote TFE coated rail. This design reduces roll moment deflection of the carriage when compared to the RGS and RGW products.
