Information

Guide tube: Chrome-plated steel, DIN 2391
Spindle: Steel
Thrust ball bearings: Steel
End cap: Plastic


GN 391 drive / transfer units are normally used in conjunction with linear actuators (GN 291, GN 292 and GN 293). They are designed to translate the rotary movement for operating the linear actuators to another point or position. (See GN 298 for examples of use.)
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 drive.
As in linear actuators, digital position indicators can be fitted.
