Hebei Z3 type swelling inner and outer cone ring, Z5 type swelling coupling sleeve, Z6 type swelling coupling sleeve

The Z7 expansion sleeve is a keyless coupling device between the shaft and the sleeve. This device can apply a clamping force to the sleeve from the outside to form a mechanical compression fit between the shaft and the sleeve, thereby transmitting torque and expanding the sleeve. It does not transmit any torque and load. ...
