The F Series is an outstanding solution for customers looking for a drive that can maximize mounting flexibility. Thanks to the housing's lateral holes, the F Series can also be side mounted directly into the machine, in addition to all the conventional mounting positions. This gearmotor guarantees elevated efficiency, reliability and low-noise operation. High torque density, a range of wide gear ratios and a compact design complete the F Series' characteristics. The F 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 F Series.
