Z2 type expansion coupling sleeve

TAG recommendation:

Z3 type swelling inner and outer cone ring Z6 type expansion coupling sleeve Z5 type expansion coupling sleeve

Product Details

The Z2 type expansion coupling sleeve is composed of an open double cone inner ring, an open double cone outer ring and two double cone compression rings. It is tightened with hexagon socket bolts. When tightening, the elastic ring is not axially relative to the hub. Compared with the Z1 type, the radial pressure and the transmitted load can be generated by the same pressing force.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 disc is widely used in packaging, printing, textile, machine tools and other machinery.
