Product description


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

In addition to the standard stroke lengths specified in the table, any stroke within the maximum stroke lengths is available upon request.

By means of linear actuator connectors, the linear movement of the lead nut can be transmitted to the outside via a drive key. The drive keys are included with the respective linear actuator connectors. In addition, a wide variety of different components are available in the connector clamp range to mount the linear actuators in place.

In order to measure the movement or the position of the linear actuator connectors, the square tube can be equipped with a longitudinal scale.
