C Series


In-line Gearmotors & Units


The C Series is designed for most standard applications in an industrial environment. The C Series offers 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 C Series to adapt to every application and 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 (BN-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) can be coupled with the C Series.
