tensioner pully

So my alternator died on me the other day and in the process of replacing that i went ahead and bought a new belt, idler pulleys, and a new tensioner pulley. Now they problem that i have is the new gates tensioner pulley i bought from napa fits good, but i can wobble it very slightly when its on the tensioner itself. So i took that one back and replaced it with another new one and it does the same thing. Im thinking screw just replacing the pulling and going with a whole new tensioner but i wanted to know it they have this type of play on a new unit. Im buying from rockauto.com and no one in town has one in stock for me to even just look at. what do you all think?
