Founded in 2003, Shanghai Reijay Hydraulic & Transmission Tech Co., Ltd focus on mechanical power transmission coupling,

hydraulic system spare parts and heat exchanger products (oil heating and cooling equipment) manufacture and export.

We also provide relevant technical supports and service. We also serve customers with design, assemble, remolding and

maintenance of industrial automation components (pneumatic, hydraulic, PLC), industrial intelligent system, hydraulic power units

and drive sections.

The jaws of the hub and the spider legs are chamfered to provide easy assembly.

The series coupling design also allows the blind assembly in tight spaces.Raised spiderdots on the legs of the spider ensure proper spacing of hubs and spider.proper installationof the coupling can provide isolation of electrical currents.check the CL dimension to ensure proper spacing between spiders and hubs.

lts rigidity and damping performance greatly improved drive system dynamic feature.The series coupling has spiders available in four different shore hardnesses.each spideroffers benefits for different vibratory, environment and torsional transmission requirments.
