Is the roller surface of cylindrical roller thrust bearings pure cylindrical? Does the roller roll in pure motion?
The ends of the roller are rolled on different circumferenceThe circumference is different and the perimeter is differentBut the number of turns of the roller is only one numberSo the roller is a cone-shaped column
