All-round maintenance, maintenance and installation of exercise bike bearing

Why is exercise bike bearing damage?
Only part of the bearing is damaged, in be used actually most applications over the design of the machine or equipment itself bearing life.
exercise bike bearing damage for many reasons, beyond the load of previous estimates, the effective seal or too tight, so lead to the gap is too small, there is in any kind of factors the special form of damage, and will leave a special traces of damage, so check the damaged bearings, can be found in the case of most kinds of the causes of damage, and give the reasons to take measures to prevent.
Generally speaking, there are more than 30 percentage is fatigue damage, and the other percentage more than 60 because of bad lubrication, pollution, caused by the improper installation method.
However, these are associated with bearing used in the industry and the situation, such as pulp industry, mostly because of pollution, poor lubrication, rather than due to material fatigue.

And exercise bike bearing damaged bearing water lead to internal rust occurs when, also once because of failure to use the low pressure oil, lead to bearing are more likely to be damaged, also has in the wrong after hitting bearing, cause is found, after loading and soon began to damage.

exercise bike bearing fatigue damage analysis of the phenomenon
Bearing from start using guide first material fatigue phenomenon appeared during the period of the length and the bearing rotating speed, the size of the load, clean lubrication failure have relations.
Fatigue is formed by the shear stress of periodic appear below the surface of the load as a result, after a period of time, the shear stress is causing tiny crack skull, then gradually extends to the surface, when the rolling piece after the split cranium, then some crack block off, form the so-called "peeling phenomenon", and then continue to expand as peeling, bearing damage in use.

Above is the description of the exercise bike bearing fatigue, it was originally occurred under the surface, while the original skin conditions are usually very mild, but increased with the increase of stress and crack block, lead to the spread of the peeling area, the damage situation usually lasts a long time, its visible stage is when noise and vibration increase.
exercise bike bearing damaged in the primary stage, is likely to be just turns hard to feel, and later found that the rotation are pitting, and once appeared pitting feeling, bearing is not can't use, just proceed in each beads and shaft gear and shaft bowl occurs more wear and more serious damage, because the bike is a way of low speed high extreme pressure type bearing, so even if the surface peeling phenomenon is serious, is not so used, but intangible silent your motivation of energy consumption, and the feeling of you is likely to be just think don't know why not ride a bad car.

So before exercise bike bearing totally destroyed it, it provides users find enough time, do not ignore the existence of this kind of friction, it will cause a decrease in the speed of riding, make long distance energy consumption greater speed slower.
If subtle for surface roughness, if there is proper thickness of lube film, the surface stress generated by the probability is quite low, which is why the choice of appropriate for the reason of engine oil for lubrication, however, if the load exceeds the oil film pressure value of pu (the fatigue load limit, such as high speed, high pressure shock), material fatigue will come sooner or later.
