The protection relay panel functions restraining from spread of accident when the electric power equipment and power lines is demaged. The design and manufacturing of protection relay panel is applied as considering application field and protection method. So,the reliability of protection relay is obtained. We provide and produce product

Introduction The Jac Wire drum coupling is designed for installation in drum drive of crain and conveying system. 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

Introduction - Muff coupling is designed as a dividing structure, therefore, it is easy to assemble, disassemble and removal from the shaft. - The system is fixed, therefore, there no backlash. because of a modified design, it transmits more torque. Much better than any other coupling. - Basic construction Designed to insert the

Introduction Jac jaw couplings are torsionally flexible and disigned for positive torque transmission. They are puncture-proof. Operational vibrations and shock are efficiently attenuated and reduced. Setting and repairing is

Introduction The Jac tire coupling using natural compounds makes couplingssuitable for use in most conditions. Handle combinations of parallel, angular and axial displacements. Installation is quick and easy . No special tools needed. Reduce torsional vibrations. Absorb shock loads. After installation. Eliminates the need for

Introduction Jac rubber couplings are easy to install and fit byeliminating most vibration, they also eliminate most noise,to improve working conditions and lengthened machine service life. Even under severs conditions they require absolutely no lubrication. They simplifies design especially in case where shaft vibration could particular

Introduction - Lubricating oil is unnecessary because the Jac disc coupling has no sliding, frictional, or moving parts. Therefore, there is no friction or noise, and energy loss is low, with no dirty oil to cope with. - Higher torsional and no backlash. For equipment such as machine tools with numerical controllers, indexing system,

DF series This product can be a wonderful solution for someone who considers how to transmit fluid, which contains big volume of sludge. It can replace general metering pump, which uses check ball valve. However, the material of head and flat valve (instead of using ball valve) is iron and rubber, so that it is not recommend to be used in

The high precision reducer implements lost motion, 1 arc min. as well as the various coupling methods (double shaft type, right angle type, clamping input type). We manufacture the product according to the customer’s specification. Unlike the conventional reducers, as it reduces the speed by the dimensional difference, it implements large
