What is a uniform thin-walled bearing?

　什么是等截面薄壁轴承？

　　等截面薄壁轴承是指径向和轴向截面尺寸相等且较薄的轴承，而普通轴承的尺寸不相等，所以单独归类为等截面薄壁轴承，主要用于尺寸要求轴承尺寸和截面都很小的场合。

　　如何存放等截面薄壁轴承以延长其寿命？

　　等截面薄壁轴承出厂时涂有适量的防锈油，并用防锈纸包装。只要包装没有损坏，轴承的质量就有保证。

　　但长期存放时，在湿度低于65%，温度20℃左右时，宜存放在离地面30cm的架子上。此外，储存场所应避免阳光直射或接触冷墙。

　　等截面薄壁轴承包装

　　内包装和外包装中的轴承制造完成并经检验合格后，进行清洗、防锈，然后装入内包装，以达到防水、防潮、防尘、防震的目的，保持轴承的质量和精度，方便使用和销售。

　　The inner packaging of uniform-section thin-walled bearings can be divided into three categories according to the anti-rust period:

　　①Short anti-rust period packaging: The anti-rust period is 3 to 6 months, which is suitable for bearings that are delivered in large quantities to the same user and put into use in a short period of time. After consultation between the two parties, based on the principle of convenience of use, simple packaging is adopted.

　　②General anti-rust period packaging: The anti-rust period is one year, suitable for general bearings.

　　③Long anti-rust period packaging: The anti-rust period is two years, suitable for special and precision bearings.

　　The inner packaging materials of uniform cross-section thin-walled bearings include polyethylene plastic tubes (boxes), kraft paper, plain and wrinkled polyethylene composite paper, cartons, polyethylene or polyethylene plastic films, nylon fastening belts or plastic woven fastening belts, waterproof high-strength plastic belts, burlap bags, etc. All of the above materials must pass the corrosion resistance test.
