Jac Coupling Company has been supplying high quality industrial power transmission couplings not only in the Korean domestic market but also in the major industrialized countries including Japan and China. The company’s business philosophy is based on a long-term approach. Jac Company is strongly committed to providing customers with excellent services and full customer satisfaction. Technical expertise is a key component of Jac Company’s business so the company takes every measure necessary to provide outstanding support for its customers at home and abroad.
Jac gear couplings conform to the "Gear Type Shaft Couplings" specified by KS (Korea Standard) and are further engineered for higher performance, based on the company's rich technical experiences and accumulated field experiment. With the cappacity of handling heavy load, Jac gear couplings are much smaller and lighter than any other couplings. Noise or vibration is hardly produced even in high speed operation.
On the other hand, Jac jaw couplings are torsionally flexible and designed for positive torque transmission. They are puncture-proof. Operational vibrations and shock are efficiently attenuated and reduced. Setting and repairing are quite easy.
In addition, our customers are able to enjoy more convenience and cut down on costs by using the Jac grid coupling. The movement of a grid in the lubricated grooves accommodates parallel misalignment and steel permits full functioning of the grid-groove action in damping out shock and vibration. Under angular misalignment, the grid-groove design permits a rocking and sliding action of the lubricated grid and hubs without any loss of power through the resilent grid. An unrestrained end float for both driving and driven members is permitted because the grid slides freely in the lubricated grooves. It can also be limited to any required amount. Torsional flexibility is the taper grid couplings to torsionally deflect when subjected to normal shock or vibratory loads.
The Jac wire drum coupling is designed for installation in drum drives of cranes and conveying systems. The Wire drum coupling can be used in the very difficult and rough operating conditions of iron and steel works and continuos heavy load operation in shore cranes. With compact design and capable of transmitting large radial load, customers can enjoy longer life and minimum loss of power angular misalignment can be allowed up to 1.5˚. With the design to decrease slip movement of rollers by construction of minimum backlash between crowned rollers and cylindrical bores, the relative movement between rollers and bores which is the cause of wear, is considerably reduced due to the natural movement of the drum. In the transmission of power, the stamping hardness of the rollers profile is produced, through which higher wear resistance is achieved.
Jac Coupling has been awarded the KOTRA Seal of Excellence since 2010.
