Special Note
We are selling 2 types of Johnson Motors as “Johnson Geared Motor – Grade A Quality” and “Johnson Geared Motor – Grade B“, the only difference between them is the quality of materials used for manufacturing the motor. All other specification including look, dimensions, working etc. are same. The “Grade A Quality” motors shows slightly more torque count than “Grade B” Johnson Motors and hence dominates “Grade B” quality motors.SKU: n/a -
