Fabtech pulleys issue

Has anyone installed the fabtech pulleys and could help me. I'm having issues with the drive belt tensioner pulley, when I tighten the bolt down the pulley can't spin freely. I'm not sure if its a problem with fabtech or an issue on all billet pulleys. When I compare the OEM to it, the OEM is much thinner. The one im taking about is the one circled in blue and the one circled in purple is what the other pulley looks like.

That is odd...when I did mine I remember a note about a marking or something needing to face out when installing them. The bolt should only tighten on the inner race of the bearing pressed into the pulley which wouldn't affect its spinning ability. Maybe try flipping it over?

Yeah I didn't get any notes when mine came in, just loose in a usps bag. The one circled purple has to face a certain direction but I've tried both ways for the one circled blue and still the same issue.
