Complete Analysis of What Are The Early Damage of Motorcycle Wheel Bearings

Motorcycle wheel bearings are mostly precision parts. The steering column, front, and rear-wheel hubs, rear chain discs, rear gearboxes of chartered cars, and other movable parts of motorcycles are usually using bearings. In addition to the selection of qualified bearings from regular manufacturers, it is very important to install and use them correctly.


When you use the motorcycle, if you find that the bearing balls or cage fall off, the working surface in the rolling channel has unconventional wear, peeling, and the phenomenon of stuck during rotation, it is mostly an installation problem. The following is an analysis of the problems that are easy to appear on each part of the motorcycle.

Front and the rear wheel hub and rear chain plate bearing

In daily use, if the car wades too deep or washes car frequently, water will enter the bearing, causing the grease in the bearing to gradually fail. This will result in serious wear of the raceways and balls in the bearing, and the clearance will increase significantly. When people assemble the front and rear wheels too tightly or too loosely, it will cause unsteady driving for a long time. Bearing seizure or loose displacement of the bearing occurs, and damages the ball cage or falls off, resulting in excessive clearance. This will cause friction between the brake disc and the wheel hub, increasing the resistance of the vehicle.


The water is very easy to expose on the rear sprocket bearing. If the adjustment is too tight or too loose, it will cause damage. If damage the bearing, you must replace it in time and adjust until the wheels can rotate flexibly without obvious clearance.

Crankshaft connecting rod small end ball bearing and ball bearings on both sides

The main reasons for the damage of the ball bearing of the connecting rod and the small head are: The oil quality is too poor or the amount of oil is too small; The temperature is too high when the engine is working. Intensify friction and heat-generating surface softening, premature fatigue peeling of the working surface. The flaked debris particles fall into the cage, causing the operation to block; The ball generates abnormal load on the cage, which intensifies the wear of the cage. Cause the cage to break and break, and lock the crankshaft connecting rod.

Rental bearings for rear wheels

General charter after shock absorption for single support, the load is large. If poor road conditions are still not slowed down, it is easy to cause wear and affect the service life of bearings.

Upper and lower bearings of directional column

Due to the failure of the front shock absorber, insufficient lubrication, or unsuitable tightening force. Cause the ball to break or peel off the working surface of the ball. It will cause the direction of the steering to become awkward or runoff, which will affect the safety of driving.
