Straight roller bearings are not held centered by a preload,they are a slip fit and bear the load applied across the length of the roller.Due to the environment they operate under they are subject to side load resulting in uneven wear which is well tolerated by this type of bearing.
Inspecting these bearings correctly requires avoiding experienced gained from inspecting tapered roller bearings,which are way less tolerant on wear,'witness marks',toe or heel wear,even the telltale bottom of the axle housing wear can be used if the rollers are not chipped or heavily galled..keep them greased and keep on going..
