Product description

Transfer units GN 391 are normally used in connection with linear actuators. They are designed to transfer the rotary movement for operating the linear actuators to another or a further position.

The transfer unit in the standard length l₁ is a special design: It is designed to turn the operating axis for the linear actuators (handwheel) by 90° together with an angular gear.

As in linear actuators, digital position indicators can be fitted.
