JAC-Gear coupling is basically conformable to the "Gear Type Shaft Couplings" specified by KS(Korea Standard) and other standards are further engineered to have them display higher performance by making the best use of its years of technical experiences and accumulated field experiments. With the capacity of handling heavy load, JAC gear coupling is much smaller and lighter than any other couplings. Noise or vibration is hardly produced even in high speed operation.
