name:

Z4 type expansion joint sleeve

description:Compared with the Z4 type, the Z2 type expansion coupling sleeve has a long joint surface and high centering accuracy. It is used in the occasions where the rotation accuracy is higher and the transmission of larger loads is required. The 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.

Detailed introduction:

Z4 type expansion joint sleeveCompared 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. The 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.

The basic dimensions and parameters of the Z4 expansion sleeve:
