Description
Gearhead GB28K is specially designed to cater to precise and compact applications in a cylindrical frame with a centre shaft. This is a planetary gearbox with all plastic gears. The output bearing is robust and is made of powdered metal (ball bearing on special request). The entire gearhead is permanently lubricated and therefore requires no maintenance. Brushed and Brushless DC Motors up to 30mm diameter are generally mounted on this gearhead to provide a compact and yet powerful drive.
