GN291.1 Square Linear Actuator, with Right or Left Hand Thread
Square linear actuators, GN 291.1 are used if the linear actuator connectors are exposed to high torsion forces.
Besides the extensive range of two-part tube clamp connectors there are a number of different components for fixing the linear actuators and to build linear actuator connectors.
In order to measure the displacement and positioning of the linear actuator connectors, the square tube can be provided with a longitudinal scale.
Sliders, connector clamps and accessories are to be ordered separately.
Square tube - Steel ST, chrome-plated SCR
Spindle with trapezoidal thread - Steel ST, ball bearings.
Lead nut - Gunmetal
End cap - Plastic
In addition to the standard stroke lengths specified in the table for linear actuators any stroke inside the maximum stroke length is available
