2014 Sportsman 850 XP HO PS rear wheel bearing size specs

I have a 2014 Sportsman 850 XP HO PS and while giving her a clean up I noticed one of my rear wheel bearings was a little loose. It doesn’t make any noise or grind and actually sounds and feels pretty good but it has a little too much play for me. Did a little research on them and it seems this is pretty common even on a new bearing but I am not comfortable sitting on a 850 at 60-70 MPH with a sloppy wheel bearing. I use alot of different bearings in my other hobby (R/C Planes and stuff) and deal with a local bearing company here that can get what-ever I need if I get him the specs. I just don’t want to tear my bike down to get them if I don’t have to. Any one know the specs on the rear wheel bearings?
