GN 147.1 linear actuator connectors are normally supplied mounted only in connection with a square linear actuator and for function control.
The square of the linear actuator connector is supplied not machined in the standard design. Together with the tolerance of the tube, this may result in a relatively large play.
This can be adjusted in one direction using the clamping screws. In the other direction (90° to it), a defined minimum play can be achieved only by appropriate machining (special design) of the square linear actuator connector.
The standard version of the clamping screw is a socket cap screw with hexagonal socket DIN 912. It can be replaced by a clamping kit GN 911
(article code see table of dimensions).
