Release bearing question

Hey guys, I just got my release bearing from partsource. Not a bad price, but it seems that it has a very slight amount of play. It was maybe .5-1mm play. I took it back and they had another one there (I guess they have to order more than 1?), and it has the same play. Is this ok? Or should I take it back for a refund and get one elsewhere?

FYI, no noise at all from the bearings, and it spins butter smooth with/without load. I can't see it being bad considering it's brand new in the package, just want to hear from those more experienced with these cars.

Thanks.
