Selecting a Planetary Gearbox
When selecting a planetary gearbox for your application it is important to take note of;
Specifications required – torque, backlash, ratio etc of the application must be taken into considerations.
Environment – some environments may leave a gearbox exposed to dust, dirt or moisture so it is important to consider this factor and select a gearbox with the correct protection.
Space – planetary gearboxes are available in various sizes, if there is limited space available then a smaller gearbox can be used.
