Need more information. Are you referring to wheel bearings, transmission bearings, differential bearing, etc. Also what type of vehicle is this? If your talking about front wheel bearing on a front wheel drive car, there are no specs or adjustments. Any play means the bearing is bad. Same goes for most 4WD vehicles. Front wheel bearing on a rear wheel drive also should not have play but if they are in good shape, they can be repacked and tightened to spec.

Heat. Bearings get discolored when they get too hot. They may have been insufficiently lubricated, or the preload was set improperly (wheel bearings need to have a little bit of preload to distribute the load more evenly).
