Double Tube Linear Actuators

With the GN 491 and GN 492 double tube linear actuators, Ganter offers the standard parts with a guide system consisting of two parallel tubes which allow different configurations and can therefore be adapted to specific requirements. While the GN 491 double tube linear actuator features a compact slider size, the GN 492 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 he 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 head screws.
