Information

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.

By means of linear actuator connectors, the linear movement of the lead nut can be transmitted externally via a follower. The followers are included with the respective linear actuator connectors. In addition, the tube clamp connector range contains many different parts for mounting the linear actuators.

In order to measure the displacement and positioning of the linear actuator connectors, the square tube can be provided with a longitudinal scale.
