For hangers and spring hangers, there is a limit of max. 4 deg rotation, therefore the horizontal movement is pending on the rod length.

For cans there is not a clear limit, but you want to make sure that if you have large displacements, your support still stay on the load plate.
Also there will be some problems due to the eccentricity of the load.

For displacements larger than 1" you may want to buy also a PTFE plate on the load plate.
