A question I asked earlier for modelling a bearing (two discs) can be done by modelling two rbe2 for each disc. The question now is how to connect the independent nodes of the two discs to eachother.
I just noticed this hasn't gotten a reply. You might have moved on from this issue, but for what it's worth: One way would be to connect the two nodes with an RBAR (if a rigid connection is what you require). One of the nodes has to be the independent node, and the other has to become the dependent.
