Haydon Kerk WGS wide guide linear screw/slide

Haydon Kerk Motion Solutions has added the WGS wide guide screw to its linear slide product line. The WGS linear slide utilises a screw-driven carriage that claims to offer reliable, continuous linear speed, while maintaining accurate positioning. Length and speed of the WGS are not limited by critical screw speed, allowing high rpm, linear speed and long stroke lengths.

The WGS slide has a compact profile that provides improved torsional stiffness and stability. An integral mounting base can provide support over the entire length, which can extend up to 2.4 m. Longer lengths are available on a special order basis.

Standard leads include: 2.54, 5.08, 12.7 and 25.4 mm travel per revolution. Other imperial and metric leads are available. There are short leads for non-back driving vertical applications, eliminating the need for brakes, as well as longer leads capable of speeds of more than 1.5 m/s, which rival belts and cables while offering positioning accuracy, repeatability, axial stiffness and lower maintenance costs.

The WGS utilises sliding plane bearings on a low-profile aluminium 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.
