Linear Actuators & Tube Clamp Connectors

Published on : Tuesday 30-11--0001

Whenever ultimate distortion resistance and flexural strength are required from linear actuators when they move and position large masses in any installation position, linear actuators with dual support are the first choice. With the GN491 and GN492 double tube linear actuators, Elesa+Ganter offers the appropriate standard parts with a guide system consisting of two parallel tubes, which allow different configurations and can therefore be adapted to highly specific requirements.

While the GN491 double tube linear actuator features a compact slider size, the GN492 works with a double slider carrying a large adapter plate. In both models, the central trapezoidal thread spindle rising left or right runs on ball bearings and is mainly intended for manual adjustment using a handwheel, but can also be motor-driven via the journal if the appropriate lubrication is used. With a stroke along the chromed, low-maintenance steel tube guides within the standard range from 100 to 300 mm, the rolled steel spindle allows the guide nut – and therefore the slider – to be positioned with ultimate precision to a stroke of 0.2 mm/300 mm. The unit is installed via the numerous fixing options including through and/or thread bores at the end pieces and at the slider. The specially designed flat recess of the through bores optionally take hexagonal screw heads or nuts, as well as the round heads of cylinder heads crews.

Other double tube linear actuators are available on request, for example with special slider sizes, with several symmetrically opposing sliders or sliders running separately and with central support. This means that Elesa+Ganter has the matching component for virtually all applications –and as always in ultimate quality and delivered the next day.

The same applies to the single linear actuator units GN 291, GN292 and GN293 with one or two sided journals and a guide tube made of chromed steel or stainless steel. Next to the units with circular cross-section, the GN291.1 with square cross-section is available for very special applications.
