I have SW2015 Premium and I was able to do what I think you are asking no problem. In the Motion Study, you have to select the bearing and the slot as a "Contact Pair" and SW will do the rest. Requires Basic Motion or Motion Analysis Mode for the Motion Study. Animation Mode doesn't allow me to use the Contact pair. So I am not sure what version of SW you are using or if these features are available to you but with the right set up, it will be a breeze. I did a simple mock up to test and you can see it in the video attached. Mine bounces a bit on the down stroke due to a lack of gravity and friction.
