Z4 Type Expansion Coupling Sleeve Features: Z4 Type Expansion Sleeve is composed of a split double cone inner ring with different tapers, a split double cone outer ring and two double cone compression rings, which are locked with hexagon socket bolts.Compared with the Z2 type, the joint surface is long and the centering accuracy is high. It is used in the occasions that require high rotation accuracy and transfer large loads.
