Frequently asked questions
What loads are plastic gears suitable for?
Plastic gears suit light-load mechanisms such as small robot drives and educational models. For high-torque drives, metal gears are a safer choice because plastic teeth can strip under heavy load.
How do I attach a gear to a motor shaft?
Match the gear's bore to your shaft diameter, then secure it with a set screw or press-fit it. Confirm the bore size before assembly, since a loose fit causes slipping.
