Feature

●Efficient Working: fix the bearing and sprocket firmly on the shaft and reduce the load when the shafts are not well aligned.
●PERFECT FIT The motor shaft coupling perfectly fits NEMA 17 stepper motors, the coupling plug has a diameter of 14mm as well as length of 25mm.
●Extensive use: our shaft coupling allows a wide application on blowers, 3D printers, DIY robots, CNC tool machines, stepper motors and more.
●Fixed Connection The coupling can connect two shafts of different diameters or one motor shaft for a firm and stable connection.
●Including 10 pieces: made of high quality aluminum alloy material, all 10 pieces allow for very convenient replacement and installation.
