Iron and carbon steel fabricated grid springs are used as indispensable parts of grid coupling. These springs are effective in improving variable flexibility as well as noise or vibration suppression capability of coupling. As its result, grid couplings can maintain excellent performance while enduring high shock load. Grid springs are accessible in barrel shaped, conical, cylindrical and other shape based choices ( 300 mm diameter). Raw materials used to design these springs conform to EN and IS norms. Based on application type, these 18.91 kg springs can maintain 2050 Nm torque.
