thrust axis

To avoid sliding that occurs in cylindrical roller thrust bearings, the taper Angle of the rollers is selected so the extended contact lines intersect on the bearing axis.

Rolling theoretical rotation axis line of the inner ring to the center axis line of bearings, thrust bearings on the shaft circle refers to the axis line.

The inflectional form and the critical value's effect imposed by circumferential initial stress character on cylindrical thin shell beard the thrust at axis, accelerating upwards erect.
