I have a Trek 7500 Hybrid bike that I want to use on my trainer. But I notice that the rear wheel had some play in it(I hadn't rode this bike in a long time). So after checking it out I found that a hub bearing was missing(It has loose ball bearings). I have found a site that sells loose bearings but I don't what type to get(carbon steel, chrome steel, stainless steel)

It's a hybrid on a trainer...it doesn't matter. Pro tip: That hub won't be smooth unless you replace the both the balls AND the cones. Grade 25 balls will be better than you need but still cheap.

Ok, thanks I wanted to use this bike instead of my carbon frame road bike, I grease the bearings and adjusted the cone nut and it doesn't seem to have much or any play on the trainer. I just didn't know if it would cause damage to the hub with the one bearing missing.

It's typical with loose bearings to have a space that makes it look like one bearing is missing when that's not the case. As you found out, the bearings probably just needed adjusting.
