Planetary Gears GSA

Planetary Gear GSA

The low-backlash planetary gearheads of the GSA series are designed for high positioning accuracy and highly dynamic cycle operation. Ground, helical toothed precision components inside the gear ensure low running noise and high running smoothness.
Thanks to its robust design, the gear unit is convincing in applications in which large radial and axial forces are exerted. The hole pattern on the output side allows easy mounting.
