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