Does anyone have ideas on how to model linear bearings for FEA?

we recently did a project with ball screws and linear rails and used spring connectors to idealize the bearings. SOLIDWORKS Simulation - Representing Ball Screws And Linear Rails In Your Analysis | SOLIDWORKS Tutorials

I'm not sure I'm completely wrapping my head around the geometry you're looking to connect together but that might be a place to start. Then you don't have to deal with no penetration.

Old thread, but in case someone comes across it, like I did, here is the updated link.
