The Z7B expansion coupling 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 and transmit torque. The expansion sleeve itself does not transmit any torque and load...
