Reply To: Simultaneous rotational and translational motion of the cylinder

What is the analysis type are you looking for? Are you modeling the parts as rigid or deformable? If you can share what are the loads and boundary conditions that are being applied then the members on the forum can comment easily.
Some suggestions - define contact between roller and horizontal members as frictional one. There should be a normal force on the roller (may be by the weight of the horizontal bar on the top).
