Jac gear couplings basically conformable to the "Gear Type Shaft Couplings" specified by KS(KoreaStandard) and other standards are further engineered to have them display higher performance bymaking the best use of its year’s technical experience and accumulated field experiment.With the cappacity of handling heavy load, Jac gear couplings are much smaller and lighter than anyother couplings.Noise or vibration is hardly produced even in high speed operation.
