Description:
Type Z7B is a keyless shaft power lock. It can replace single keyway and spline ,in order to realize the connection between machinery parts (such as gear wheel,flywheel) and shafts,so the loading can be transmitted.Through the function of high strength of bolt when locking device is working,enormous strengh of tight holding power between hub, inner loop and shaft are produced.When bearing the weight and loading depend on connection power between locking device and machinery and additional frictional torce to transmission torsion or power on shaft.

Parameter of Z7B Shaft locking device bore 24mm to 80mm keyless power lock
