Integrated screw/slide system improves torsional stiffness

The WGS has a unique, compact profile that provides improved torsional stiffness and stability versus Haydon Kerk’s existing RGS and RGW slide products. An integral mounting base can provide support over the entire length, which can extend up to 8ft (2.4m).

Standard leads include .100, .200, .500 and 1.00" travel per revolution.There are short leads for non-backdriving vertical applications, eliminating the need for brakes, as well as longer leads capable of speeds of more than 60" per second (1.5m/s), which rival belts and cables while offering superior positioning accuracy, repeatability, axial stiffness and lower maintenance costs.

The WGS utilises 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 a Haydon Kerk manufacturing facility.

All moving surfaces include Kerkite high-performance polymers running on a Kerkote TFE coating. The slides come with wear-compensating, anti-backlash driven carriages. Additional driven or passive carriages can be added, along with application specific customisation. Linear guides without the drive screw also are available.
