GN 291.1 Square linear actuators with right or left hand thread


Product description


Square linear actuators GN 291.1 are used if the linear actuator connectors are exposed to high torsion forces.

In addition to the standard stroke lengths specified in the above table for linear actuators any stroke inside the maximum stroke length is available.

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.
