Worm gearboxes RI - RMI
The worm gearboxes are produced from quality materials and with modern technology. Therefore these gearboxes ensure high reliability and a long period of service.
The cases of gearboxes with low power are produced from aluminium alloy SGALSi91 UNI., cases of gearboxes wit larger power are made of grey cast-iron G20 UNI 5007.
Gearboxes are delivered in versions with motor (typ RMI), without motor (typ RI) with the option of mounting on foot (e.g. RI S, RI I, RI D), or on flange (e.g. RI FL, RMI FL, RI P, RMI P, RMI PP) for great range of performances and speed.
The gear can be increased through a combination of two worm gearbox (type CRI) or using helical worm gearboxes (type CR). The gearboxes are delivered for various mounting positions.
