滚动轴承的密封装置可以防止润滑剂的泄漏和灰尘、水或其它污物的侵入，也使滚动轴承具有良好的工作环境，使其具有最大的工作性能。
The sealing device of the rolling bearing can prevent the leakage of lubricants and the intrusion of dust, water or other dirt, and also make the rolling bearings have a good working environment, so that they have the maximum working performance.
凭借我们在扬州SKF轴承领域的丰富经验，我们拥有各种先进工程产品的开发、制造和应用所必需的知识和专长。小型轴承，如微型轴承，只有0.003克，大轴承高达三十四吨。
With our rich experience in the field of SKF bearings in Yangzhou, we have the knowledge and expertise necessary for the development, manufacture and application of various advanced engineering products. Small bearings, such as miniature bearings, are only 0.003 grams, with large bearings up to thirty-four tons.
事实上，在滚动扬州SKF轴承中，一些轴承是自密封的，对于轴承没有密封装置，可以采用密封的方法，也可以使用。
In fact, in the rolling Yangzhou SKF bearing, some bearings are self sealing, and there is no seal for the bearings. It can be sealed and can be used.
通常，外部密封可分为2种类型，一种是非接触式密封，另一种是接触式密封。对于轴承外密封性能装置，在端盖中制造具有各种特性的密封装置。那么，我们该如何选择呢？除了轴承密封外，我们还必须考虑以下几点。
Usually, external seals can be pided into 2 types, one is non-contact seal and the other is contact seal. For the bearing external sealing performance device, a sealing device with various characteristics is manufactured in the end cover. So, how do we choose? Besides bearing seals, we must consider the following points.
1，扬州SKF轴承润滑油和润滑油类型；
1, Yangzhou SKF bearing lubricating oil and lubricating oil type;
2，轴的支撑结构具有允许角度偏离的优点。
2, the supporting structure of the shaft has the advantage of allowing the angle to deviate.
3，轴承的工作环境和占用空间的大小；
3, the bearing's working environment and occupying space.
4，轴承的工作温度；
4, the working temperature of the bearing;
5，密封表面的圆周速度；
5, the circumferential velocity of the sealed surface;
6，制造成本。
6, manufacturing costs.
在滚动扬州SKF轴承中，外圈安装在轴承座孔中，通常不旋转，而是与轴匹配，并与轴一起旋转。滚动轴承使用和维护非常方便，其性能也非常可靠。然而，在使用中，不可避免的外部或内部因素可能导致损坏或磨损。
In rolling Yangzhou SKF bearings, the outer ring is mounted in the bearing seat bore and usually does not rotate, but matches the shaft and rotates with the shaft. Rolling bearing is very convenient to use and maintain, and its performance is also very reliable. However, in use, unavoidable external or internal factors may lead to damage or wear.
一般来说，滚动扬州SKF轴承磨损有多种形式，如磨料磨损、微动磨损、粘着磨损、腐蚀磨损等。磨损的原因如下：
Generally speaking, the rolling Yangzhou SKF bearing wear has many forms, such as abrasive wear, fretting wear, adhesive wear, corrosion wear and so on. The reasons for the wear are as follows:
1，润滑不良。在这种情况下，相对运动表面容易粘、磨损甚至烧坏。
1, poor lubrication. In this case, the relative movement surface is easy to stick, wear or even burn out.
2，轴承外尘进入、润滑油中含有杂质、轴承清洗等，会引起磨料磨损。
2, bearing external dust entering, lubricating oil containing impurities, bearing cleaning and so on, will cause abrasive wear.
3，湿气、湿气和酸都侵入轴承，造成腐蚀和腐蚀。
3, moisture, moisture and acid intrude into bearings, causing corrosion and corrosion.
4，扬州SKF轴承不旋转，在小的振动状态下会长期磨损微动。轴承是由轴承制造的。轴承在全球轴承行业中处于领先地位。标准产品有20000多个轴承。
4, the SKF bearing of Yangzhou does not rotate, and it will wear fretting for a long time under the condition of small vibration. Bearings are made of bearings. Bearing is in the leading position in the global bearing industry. The standard product has more than 20000 bearings.
