rigid body motion of a "shrink fit" ring on a shaft

So I have an assembly with a press fit. Image a bushing pressed onto a shaft. I also have the friction switch turned on and a .8 friction factor (steel on steel) defined. The results show the induced stresses from the "shrink fit" but for some reason, If I dont constrain the ring, I have solid body motion of the ring along the shaft if there is an applied axial load on the face of the ring. Am I missing something? Shouldnt the ring stay fixed axially due to the press fit? The applied axial load is not significant... Any help is appreciated. Thanks.
