As a common vehicle for modern young people, motorcycles are extremely maneuverable, which requires a large number of bearings in each moving part (such as steering column, front and rear wheel rims, rear chain plate, rear chain plate, etc.) to cooperate with each other, which are very precise parts. Bearings manufactured by regular manufacturers are usually inspected as qualified products when leaving the factory, but the correct installation and use are the same. During the use of motorcycles, if the bearing ball retainer falls off, the working surface in the rotating groove is abnormally damaged, falls off, and the rotation is stuck, it is a quality problem of the bearing itself, and there are many problems in application and installation. The following is a detailed analysis of the problems that are prone to occur in various parts of motorcycles:

The support on the chain behind the front and rear wheels. Because the customized products of mountain bike headset bearings are too deep or frequently washed in daily use, water flows into the bearings, causing the grease in the bearings to slowly fail, causing serious wear of the rotating grooves and balls inside the bearings, and significantly increasing the side clearance; the front and rear wheels are installed too tightly or too loosely when leaving the factory or selling, which will cause unstable operation, bearing jamming or loose support, ball retainer damage or fall off over time, resulting in a large gap, causing friction between the brake and the wheel hub, and increasing driving resistance; the support of the rear sprocket is easy to get water, or change too tight or too loose, which will cause wear, so when cleaning or passing through deep water pits, pay special attention and repair.

The price of headset bearing manufacturers is very high, so it is necessary to control the effect of the bearings. If they are damaged, they must be properly adjusted during maintenance until the wheel rotates flexibly and there is no obvious side clearance. The large and small head rollers of the crankshaft connector and the spherical bearings on both sides are usually more susceptible to damage in two-stroke engines. The main faults that cause the crankshaft size roller bearing are: extremely low lubricating oil quality or insufficient oil: high temperature when the engine is running, making the friction heat generating surface softer, premature fatigue and shedding of the working surface, and the falling particles enter the steel column bracket, causing operation obstruction; the roller causes abnormal load on the cage, causing serious damage to the cage, resulting in cracking, breaking, and jamming of the crank connecting rod.

If the four-stroke engine is replaced with a counterfeit or has a long life, the lubrication effect will decrease, the damage will be aggravated, and impurities will easily block the oil circuit; after the installation or overhaul of a new car, due to insufficient site cleaning or hard impurities on the equipment often enter the support channel, the bearing will not rotate smoothly; the different centers of the crankshaft press or the movement of the gears during installation will cause the bearing to rotate and lift, causing damage.

The front fork bowl bearing manufacturer will install the bearing on the rear wheel of the car. Generally, the rear shock absorbers of chartered vehicles are single-supported and have a large load capacity. If the road conditions are bad and the vehicle does not slow down, it is easy to cause damage and affect its lifespan. It is easy to get water when cleaning, so special attention should be paid. The upper and lower bearings of the directional column. Due to the ineffective front damping, insufficient lubrication or poor upper and lower torque, the ball will break or detach, causing the steering to become astringent or deviate, thus affecting the safety of driving.

Generally speaking, bearing failures are mainly caused by poor lubrication, improper installation, improper side clearance and poor working environment. If they are not discovered or repaired in time, they will cause great losses and even affect the safety of driving.
