BS.F Series Helical-Bevel Servo Gear Units

Low rotational clearance

thanks to the high torsional rigidity of the gearing geometry throughout the entire gear unit service life.
Large gear ratio range

thanks to the helical gear input stage combined with a hypoid output stage.
A perfect combination

with the B5 mounting flange that optimally integrates the drive unit into every application.

Features

Low-backlash helical-bevel servo gear units
Designed for nominal torques of 40 Nm to 1220 Nm
All variants with B5 mounting flange; torque arm or mounting flanges for foot/face end are optional (can be optionally integrated into the relevant application)
High maximum overhung loads between 2600 N and 36 000 N can be integrated
The rotational clearance remains constant over the entire gear unit service life
Easy mounting of (third-party) motors using the EBH motor adapter
Five standard output variants available (additional upon request):
- BSF: Solid shaft
- BSKF: Solid shaft with key
- BSBF: Flange block shaft (EN ISO 9409)
- BSHF: Hollow shaft with shrink disk
- BSAF: Hollow shaft with key (shaft-mounted gear unit)
