Motorcycle KOYO bearings many of the various areas of activity (such as the steering column, front and rear wheels, rear chain drive, chauffeur drive rear gear box), is a precision part. Regular factory bearing factory testing is eligible, but proper installation is also very important. Motorcycles in use, if the bearing ball bearing cage particles, rolling grooves face inside a non-normal wear, spalling, the turning of the lock behavior, belongs to the bearing itself quality problems rarely, use more installation problems. Next, problems on motorcycle parts-by-analysis, so that suppliers, service industry and vehicle owners are attracting attention, avoid unnecessary damage.
1. the front and rear wheels and rear bearings on a keyboard. Due to owners in daily using Shi, wading too deep or often wash car, let water into bearing, make bearing in the of grease gradually failure, formed KOYO bearing within scroll slot and the ball wear serious, tour gap obviously increases; if factory or sales Shi before and after wheels Assembly have had tight or had pine, time a long caused lane not steady, bearing card delay or bearing displacement pine open, ball keep frame damaged or shedding, formed gap had large, make brake disc and wheel phase friction, increased has lane of resistance; Hou chain roulette Shang of bearing, Easily into the water or adjusted too tight too loose will cause damage, so the owners at car wash or too deep puddle time should pay particular attention, maintenance checks in a timely manner. If damaged replacement must be in place, adjust the wheel rotational flexibility, no apparent clearance shall prevail.
2. crankshaft connecting rod head size roller bearings and ball bearings on both sides, usually two-stroke engine more prone to damage. Caused connecting rod size head roll column bearing damaged of main causes is: oil oil too poor or oil volume too small; engine work Shi temperature high, increased friction health hot surface softened, premature appeared face fatigue peeling, peeling off of particles into steel column of keep frame in the, led to running block; roll column on keep frame produced exception load, increased keep frame of wear, led to keep frame break broken, crankshaft connecting rod hold died. And four trip engine if replaced of oil for shoddy products or using period had long, lubrication effect reduced make wear increased, easy produced impurities plug oil road; new car Assembly or overhaul Hou, due to scene enough clean or correction Shi by with apparatus with of hard mass foreign body into bearing Groove road within, caused bearing turned blocked; crankshaft pressure loaded of different heart or installed Shi crank dislocation, make KOYO bearing turned load increased, caused damaged.
3. chauffeur drive on a rear wheel bearing. General car rear shock for support, load-carrying capacity of a large, bad road conditions will not slow, prone to wear, affecting life, should pay attention to the water when you wash.
4. steering column upper and lower bearings. Due to the shock before failure, insufficient lubrication or fastening shall not apply, causing a breaking ball or ball-face peeling, form deviation towards Fase or affect driving safety.
To sum up: KOYO bearings damage mainly to poor lubrication, installation is not in place, improper clearance and environmental conditions and other factors, if it does not detect or repair, it will cause large losses or affect driving safety. Therefore, suppliers, dealers, repair workshops and the owners attention, avoid the occurrence of such an accident.
