Frequently asked questions
What shaft size does it fit?
The bore is 2.05 mm and the listing states it is used with a 2 mm shaft, so it fits a 2 mm shaft with slight clearance.
Is it suitable for heavy robots?
It is designed for light model aircraft. For heavy robots or applications that need high grip and load capacity, a rubber tread is generally a better choice.
