Product Description

Product Description

 

 

       Double ball rubber joint can be divided into single ball, double ball, different diameter body, curved ball and wind pressure coil. A tubular rubber piece consisting of an inner and outer rubber layer, a cord layer and a traveller is vulcanized and formed and then loosely combined with a metal flange or a parallel joint.
 

Product Parameters

 

Double sphere rubber bellows coupling is generally consist of the inner and the outer rubber layer and fabric reinforced layer (the enhancement layer has a multilayer spreading cord fabric), vulcanization molded in high temperature and high pressure , then assembly together with rubber tube and metal flange or parallel joint sleeve.
