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


GN 291.1 Steel, Square Linear Actuators, With Left or Right Hand Thread Material: SCR - Steel, chrome-plated finish

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.

Mediante conectores con actuador lineal, es posible transmitir el movimiento lineal de la tuerca principal de manera externa por medio de una guía. Las guías están incluidas con sus conectores de actuadores lineales correspondientes. Adicionalmente, la gama de conectores de sujeción de tubos contiene varias piezas diferentes para montar los actuadores lineales.

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