Claw type surface to surface design, has the function of protecting, vibration and shock can produce effective damping and reduce the running in process. Claw type teeth two sleeve are offset in the circumferential direction, in the gap in a quincunx elastic body of involute. When small deviations in the installation, the elastic body avoids the stress concentration. Can effectively compensate the axial, radial and angular displacement. Column pin coupling elastomer old-fashioned type of large volume, shear effect, easy to damage, while the elastic body new claw type couplings only under the extrusion pressure, so it can withstand greater load, better wear resistance, longer service life. And both the level of installation, and can be installed vertical.

Characteristics of CJ series coupling products:

1 has the advantages of simple structure, stable performance, stable operation

2 three component structure, easy installation and maintenance.

3 hub and elastic body, a variety of materials to choose from, to ensure that all can work stably in various environments.

4 using a surface matching claw type shaft hub and involute arc elasticity, can avoid the stress concentration, the effective transmission of higher torque, more resistant to abrasion, longer service life.

A small protuberance pad 5 elastic body, can isolate the metal shaft hub contact in coupling installed, effective insulation, no need of lubrication. Coupling of deviation of the remedy is deformation occurs through the elastic force at the finish.



made by injection with high quality polyester or mould CSM/SBR. It is designing and special for all kinds of metal shaft coupling with very good performance of high tensile strength, high wear resistant, high elastic resilience, water resistant, oil resistant and excellent fatigue resilience, high impact resistant etc. We have full sets moulds and supply full range of gear J series couplings with high quality and excellent experience. Apply to all kinds of industrial metal shaft coupling.
