Z5 type expansion coupling sleeve

Compared with the Z5 type expansion sleeve, the taper of each cone ring is the same, and there is a flange in the middle of the inner ring, which is easy to disassemble. The Z4 type has a longer joining surface and a smaller taper, which is used in occasions where large loads are transmitted and high centering accuracy is required.
