Servo Gearmotor BSF Series
BSF series.
The low backlash BSF helical-bevel servo gear units are designed for the 40 to 1500 Nm (350 to 13200 lb-in) torque classes. The permitted acceleration torques are significantly higher than these values.
All versions are equipped with a B5 mounting flange and optional foot mounting and torque arm. Because of this, these drive units can be optimally integrated into existing applications. The combination of a helical input stage and a hypoid output stage results in ratio ranges which can be covered by the single-stage bevel (wheel) and hypoid gear unit or by the single-stage helical-worm gear unit with high transmission quality. The circumferential backlash remains constantly low throughout the gear unit’s service life.

- BSKF: Solid shaft with key
- BSBF: Flange block shaft (EN-ISO 9409)
