What is meant is you warm the bearing to the point that when you insert it into the bearing hole that it melts the plastic a bit so it slides into the hole.

I put the part in an oven on low. I take it out every minute and hit it against a hard surface. When the tap turns to a thud you are ready to insert the bearings. I have heard reports that you can do this also by heating a bearing with a hot plate or heating the part with boiling water.
Heating the part until you get a thud I can understand but but "expanding" the the bearing by heating it does not make sense.
