Features: Z2 type expansion sleeve is composed of an open double cone inner ring, an open double cone outer ring and two double cone compression rings.Tighten with hexagon socket bolts, the elastic ring does not move axially relative to the hub during tightening. Compared with the Z1 type, the same compression force can generate greater radial pressure and transmit greater load.In order to facilitate disassembly, there are screw holes for disassembly on a compression ring, and there are 2 to 4 holes along the circumference.The locking coupling plate is widely used in packaging, printing, textile, machine tools and other machinery.
