进口INA轴承有一定的生命周期，没有其余产品是好的，轴承也不同于其余行业。进口轴承的使用寿命不按天数计算。例如，我们6330深沟球轴承的使用寿命是58694h连续运行，也就是说，深沟球轴承的极限运行时间很长。当然，如果连续使用，会对轴承造成更大的损坏。
Imported INA bearings h***e a certain life cycle, no other products are good, bearing is different from other industries. The service life of imported bearings is not calculated according to the number of days. For example, the service life of our 6330 deep groove ball bearings is 58694h continuous operation, that is to say, the limit operation time of deep groove ball bearings is very long. Of course, if used continuously, it will cause greater damage to bearings.
对于轴承的贮存，***佳贮存温度为20℃左右，无明显的温度变化。这里允许的温度变化是（48小时内的***大温度变化不超过3摄氏度）。这在INA轴承存放标准中有规定。据有关公司介绍，轴承库的温度可控制在30摄氏度左右，低于35摄氏度，48小时内温度变化不应超过10摄氏度。
For bearing storage, the optimum storage temperature of *** is about 20 C, and there is no ***ious temperature change. The allowable temperature change here is (within 48 hours, the *** temperature does not exceed 3 degrees Celsius). This is stipulated in the INA Bearing Storage Standard. According to the company concerned, the temperature of the bearing library can be controlled at about 30 degrees Celsius, below 35 degrees Celsius, and the temperature change should not exceed 10 degrees Celsius in 48 hours.
受损区域是什么？他们的比例是多少？
What is the damaged area? What's their proportion?
一．轴承安装不当（约16个百分点）
1. Improper installation of bearings (about 16 percentage points)
1。轴承安装时，锤对轴承危害***大，是轴承变形的主要原因。
1. When bearing is installed, hammer is harmful to bearing, which is the main cause of bearing deformation.
2。安装不到位，安装偏差或未安装在INA轴承位置，导致轴承间隙过小。内外环不在同一旋转中点，导致不同的中点。
2. Installation is not in place, installation deviation or not installed in INA bearing position, resulting in too ***all bearing clearance. The inner and outer rings are not at the same midpoint of rotation, resulting in different midpoints.
建议：安装后选择合适或专ye的轴承安装工具，并用专用仪器进行测试。
Suggestion: Select suitable or special Ye bearing installation tools after installation, and use special instruments for testing.
二．据调查，润滑不顺畅（约50个百分点）是轴承过早损坏的主要原因之一。主要原因有：润滑油或润滑油加注不及时；润滑油或润滑油加注不到位；润滑油或润滑油选用不当；润滑方法不正确等。
2. According to the investigation, the poor lubrication (about 50 percentage points) is one of the main causes of premature bearing damage. The main reas*** are: not timely filling of lubricating oil or lubricating oil; not in place filling of lubricating oil or lubricating oil; improper selection of lubricating oil or lubricating oil; incorrect lubricating method, etc.
建议：选择正确的润滑油或润滑剂，并使用正确的润滑和加注方法。
Suggestion: Choose the right lubricant or lubricant, and use the right lubrication and filling methods.
三．疲劳（约34个百分点）
3. Fatigue (about 34 percentage points)
疲劳损伤是INA轴承损伤的一种常见方式。疲劳损伤的常见原因有：轴承长期超负荷运行；***不及时；***不当；设备老化等
Fatigue damage is a common way of INA bearing damage. Common causes of fatigue damage are: long-term overload operation of bearings; untimely maintenance; improper maintenance; aging of equipment, etc.
四．污染（约14个百分点）。
4. Pollution (about 14 percentage points).
污染也可能导致轴承过早损坏。污染是指灰尘、金属屑等进入轴承内部。主要原因有：轴承包装在使用前过早打开，造成污染；安装时工作环境不干净，造成污染；INA轴承工作环境不干净，污染工作介质等。
Pollution may also lead to premature bearing damage. Pollution refers to dust, metal chips and so on into the bearing interior. The main reas*** are: premature opening of bearing packaging before use, causing pollution; unclean working environment during installation, causing pollution; unclean working environment of INA bearing, polluting working media, etc.
总结分析问题：
Summarize and analyze the problems:
进口轴承早期损坏的主要原因是润滑不当。为了保持进口轴承的良好使用，润滑不应忽视。有些是由于安装，因为使用进口轴承的操作人员和安装人员基本上都装有轴承，所以他们非常熟悉INA轴承的安装步骤，不会犯这样的错误。很少，但仍有许多不当操作。
The main cause of early damage of imported bearings is improper lubrication. In order to maintain the good use of imported bearings, lubrication should not be ignored. Some are due to installation, because the operators and installers using imported bearings are basically equipped with bearings, so they are very familiar with the installation procedures of INA bearings, and will not make such mistakes. Very few, but there are still many improper operati***.
