How to give prescribed displacement to a rigid domain?

In modeling a metal forming process, I have to model the roller in 2-D axisymmetric problem, and the roller is a rigid body. One way of doing it, take a small rectangle as a roller in a 2D axisymmetric problem and then give this domain as rigid domain, but then there is no option for giving a prescribed displacement in the radial direction for roller.
How to model it? Is there is any other option to model rigid roller motion in 2D axisymmetric problem?
Thank you!

A rigid body in an axisymmetric model cannot be moved radially, since that would increase its diameter and thus its volume.
You can, for example, use an ordinary elastic domain and prescribe its displacement.
