Axle casing installation Rolling journal and bearing journal wear, leading to its axis, with Songkuang between the hole, the bearing inner race in the journal slide turn cause friction surface wear and tear. Bearing inner race in the journal slip severe, will produce high temperature, the journal annealing reduced strength of the material damage. Axle casing seamless steel pipe is made, after bending, grazing between the axle and the sleeve both abnormal sound, and even affect the normal meshing planetary gear, accelerated wear, leading to tread swing.
Axle tube stop on the axle housing or casing screw threaded bore hole wear, after the stopper screw cut, resulting in the sleeve and can not stop moving, this will cause wheel Yi threaded shaft head wear, the bearing axial moving wheels swing in operation, an increase of driving resistance, affect the braking performance, the tire malignant abrasion, severe under excessive axial force, will have a "flywheel" accident.
