GN 291.1 Square Linear Actuators Steel, With Left or Right Hand Thread


Product description


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

Along with our extensive range of tube clamp connectors, there are a number of additional components for mounting on linear actuators to construct slide units.

The two-part tube clamp connectors range includes a wide variety of different components for fixing linear actuators and for setting up linear actuator connectors.

In order to measure the movement and positioning of the linear actuator connectors, the square tube can be fitted with a longtiudinal scale.
