name:

Z7C type expansion joint sleeve

description:The Z7C 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 to transmit torque and expand. The tight sleeve itself does not transmit any torque or load.

Detailed introduction:

Z7C type expansion joint sleeveIt is a keyless coupling device between the shaft and the shaft sleeve. This device can apply clamping force to the shaft sleeve from the outside to form a mechanical compression fit between the shaft and the shaft sleeve to transmit torque. The expansion sleeve itself does not transmit any Moment torque and load.
