Stuwe GF 150-21X60XB Shrink Disc Coupling

STÜWE GF 150-21X60XB Shrink Disc Coupling is a flange-type Cardan shaft coupling from the STÜWE GF family, designed to join flanged hubs on mating shafts using a shrink-disc mounting system. The GF 150-21X60XB variant features an outside diameter of 170 mm and is part of the GF 150 series, a configuration described in STÜWE’s literature as a Cardan shaft connection with a flange-bolt pattern. It uses a flange bolt arrangement of 8 x M12, enabling integration with standard STÜWE flange configurations, and the unit weighs about 7.0 kg, making it suitable for mid-size power-transmission assemblies. This specific GF model is intended for mechanical drives requiring a robust, axial-fixed connection between shaft and hub in Cardan shaft installations, such as industrial drive trains. The GF 150-21X60XB designation distinguishes its dimensions within the GF lineup, while preserving STÜWE’s shrink-disc mounting approach for secure, backlash-minimized coupling.
