SF-10 自润滑卷制轴承 Self-lubricating bearings

■ 材料组织结构 Structure

1、  聚四氟乙烯与铅混合物 PTFE with lead 0.01-0.03mm

2、  球形青铜粉 Porous bronze 0.2-0.3 mm

3、钢背 Steel backing

4、  镀锡或镀铜 Copper/Tin plating 0.002mm

■ 应用特点 Application characteristics

1、  无油润滑或少油润滑，适用于无法加油或很难加油的场所，可在使用时不保养或少保养。
　　It may be used where no oil can be applied or oil is difficult to be applied.

2、  耐磨性能好，摩擦系数小，使用寿命长。
　　It has the advantage of low wear,low friction and with long life.

3、  有适量的弹塑性，能将应力分布在较宽的接触面上，提高轴承的承载能力。
　　Load will spread over a wider area due to the bearing material's elastic nature.

4、  静动摩擦系数相近，能消除低速下的爬行，从而保证机械的工作精度。
　　Low stick slip properties ensuring accuracy of machine operation under low silding speeds.

5、  能使机械减少振动、降低噪音、防止污染，改善劳动条件。
　　Low vibration,low noise and non-pollution in operation.

6、  在运转过程中能形成转移膜，起到保护对磨轴的作用，无咬轴现象。
　　PTFE and Lead film is transferred to the mating shaft to improve running properties.

7、  对于磨轴的硬度要求低，未经调质处理的轴都可使用，从而降低了相关零件的加工难度。
　　It can be used in low hardness of mating shaft,so the shafts processing is easy.

8、  薄壁结构、质量轻，可减少机械体积。
　　The machine will be compact because of the thin thickness and low weight of the bush.

9、  钢背面可电镀多种金属，可在腐蚀介质中使用；目前已广泛应用于各种机械的滑动部位，例如：印刷机、纺织机、烟草机械、微电机、汽车、摩托车与农林机械等等。
　　Electro plating is plssible to prevent corrosion.It is widely used in various sliding motions of defferent kind of machines such as textile machine,tobacco machines,hydraulic vehicles Automobiles,agriculture machines and so on.

　 可供非标产品：直套，翻边轴套，止推垫片，板材，轴瓦，滑板，钢套组合件。
　　 Provide non-standardized products:Cylindrical bushes,flanged bushes,thrust washers,flat strip material,half bearing, wear plate,SF-10 with steel bush.
