How to store thin-walled bearings with uniform cross-section?

　　Uniform-section thin-walled bearing is a bearing with a special structure. It also needs to be stored with special care. Only in a suitable environment can the accuracy and quality of the bearing be maintained.

　　1. Thin-walled bearings with uniform cross-section should be stored in a clean and dry environment, and the temperature and humidity should be controlled during transportation and storage. The temperature and humidity should be within an acceptable fixed range and should be kept at least 30 cm above the ground.

　　2. Some thin-walled bearings with equal cross-section have a certain shelf life. For example, bearings with dust covers and oil seals will have a larger starting torque than new bearings after being stored for a period of time. At the same time, since the lubricating properties of grease will be destroyed after long-term storage, the turntable should regularly inspect and maintain the bearings.

　　3. In order to ensure the normal and reliable operation of uniform-section thin-walled bearings, sufficient lubrication must be applied to prevent direct metal contact between rolling elements, raceways and retaining cages, which may cause wear and corrosion on the bearing surface. Therefore, in various applications, it is important to choose suitable lubricants and lubrication methods, and correct maintenance is also required.

　　4. The actual choice of lubricant is mainly based on operating conditions, namely temperature range, rotational speed and ambient environment. If reliable lubrication can be guaranteed, and the operating temperature remains unchanged while the lubricant dosage is small, but it also plays other roles such as sealing or heat dissipation, the lubricant dosage of thin-walled bearings with equal cross-section will increase. Therefore, when installing the bearing, the grease will generally fill the remaining space of the spherical roller bearing, and can only control 1/3-1/2 of the remaining space in the bearing box, which can easily lead to overtemperature.

　　In recent years, the market demand for uniform-section thin-walled bearings has continued to increase with a good momentum. Consumers have encountered many problems during their use. In response to these problems, uniform-section thin-walled bearings provide you with some solutions, which we hope will be useful to you.

　　Why does the sealing performance of thin-walled bearings with uniform cross-section decrease?

　　其现象是：摩擦力矩大;防尘、防尘等性能差。

　　原因是轴承具有特殊的结构：壁薄、体积小、重量轻、密封空间小、刚性差、易变形等。轴承零件包括密封件的热加工、冷加工和检测带来很大困难，很难提高其加工精度。目前市场上这种类型的密封结构和尺寸基本一致。由于加工误差，密封性能不好或摩擦力矩大，达不到轴承的要求。

　　解决方法：为满足轴承的密封要求和摩擦力矩要求，结合易变形、尺寸公差的轴承零件的加工精度和密封圈的加工精度，根据有限的轴承空间，单独设计密封圈的结构尺寸，弥补轴承零件和密封件的加工精度误差，达到预期效果，满足用户要求。

　　为什么等截面薄壁轴承会出现漏脂的问题?

　　现象是轴承内的润滑脂从密封唇溢出。

　　原因是轴承结构尺寸特殊，密封空间小，限制了密封结构的合理性。

　　解决方法：选择合理的工艺方法，通过多次工艺试验，在满足使用要求的前提下，杜绝密封轴承漏脂现象。

　　为什么转动时轴承会卡死?

　　现象是：等截面薄壁轴承在轴向力或径向力的作用下转动时，手感时大时小，运转不畅的感觉。否则会发生高速旋转、振动和噪音。

　　原因是：轴承不干净，工作面有污垢或工作面粗糙损坏。

　　解决方法：选择合适的清洗液和清洗方法，严格控制工作面质量，改进检查方法，保证轴承清洁无异物。
