How to mate a cylinder to a slot produced by an equation driven curve.

I posted this earlier as a new discussion. I realized my mistake and am reposting this as a question. I have searched the forum and Google for several hours, but haven't had any luck. I am trying to mate this bearing to the inside of this sine wave groove that was produced by an equation driven curve. Everything I have tried has not worked. I am not sure if it is possible. Any help would be appreciated.
The link to the assembly is

Thank you

Try using the tangent mate. You may have to mate it to a specific curve or face.

Thank you for the reply. I have tried the tangent mate with both the cylindrical face and the edge of the roller. Neither worked for me.
I can get it to go half way around tangent to the edge only becuase the slot was mirrored and not continuous. I tried adding a composite curve but can't seem to use that in an assembly. Anyway. I had to add a mate connecter some distance off the bearing. set that connector cylindrical mate to it rotates about the center and then set the bearing face tangent to the edge of the slot.

if you can make the slot continuous, it should work 360 deg.
now it goes 360 but stops at an end. I added a fillet to make that edge tangent at the top
My guess is it's an issue with numerical approximation and self intersection; as well as the way in which the offset is calculated in Sketch 3, and the implementation of Wrap. I don't have an answer, but this might help:
Hey @chad_jensen577,
Have a look if this Tech Tip and document help you to set up your mates using a curve and tangent mates for the motion:

Hope this helps. Cheers
