The C Series is designed for the requirements of standard tasks in the industrial environment. These series achieve first-rate reliability, efficiency, robustness, and a wide output torque range. The extremely wide range of gear ratios, achieved through 2-, 3- or 4-stage versions, allows the customer to adapt the C Series to every application and to find the perfect match for output speed requirements. The C Series can be completed with a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors both IEC and compact (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) can be coupled with the C Series.
