Adapters for Fitech servo

Help & Support Robot Parts
1

good evening. I have an Fitech servo and would like to buy a hub shaft and shaft adapter for it. The ones I bought (in which I thought would work) have a spline diameter that is too big. I have been told that the spline is a 3F Standard Futaba Spline, but I guess that does not help me (a rookie at this).

Will these parts fit it?

Hub shaft: https://www.robotshop.com/en/actobotics-futaba-servo-shaft-hub-1-2.html

Thanks for your support and patience as I learn more about robotics.

Hello @burrism,

In motor datasheet, it says that spline has 25 tooth. Since you have information it is a 3F Standard Futaba Spline, than that is probably correct, according to this: https://www.servocity.com/servo-spline-info

Now, for your shaft adapter, I’ve found this: https://www.servocity.com/25t-futaba-set-screw-shaft-coupler
where it says it fits on 3F Standard Spline (25T), which is ok.

For hub shaft, https://www.servocity.com/servo-shaft-hub-500, it also says that it fits on the 25 Tooth (3F/H25T) Spline.

So, all of these should fit :slight_smile:
