Features: Z2-type expansion sleeve consists of an open double cone inner ring, an open double cone outer ring and two double cone compression ring. With the hexagon socket bolts tightened, the elastic ring does not move relative to the axial movement of the hub, compared with the Z1 type, the same compression force can produce greater radial pressure, the transmission of greater load. In order to facilitate the demolition, in a compression ring with a removable screw hole, along the circumference of a total of 2 to 4. Locking connection plate is widely used in packaging, printing, textile, machine tools and other machinery.
