JDB-650自潤滑軸承，屬于滑動(dòng)軸承的一個(gè)系列，石墨銅套 ,銅套加石墨是在高力黃銅（主要化學(xué)成份 Cu Al Mn Fe Ni Zn 百分比分別為：60～66% 5.0～7.5% 2.5～5.0% 2.0～4.0% 0.2～0.5% 22～28% .）的基體上，鑲嵌石墨固體潤滑劑的一種高性能固體潤滑產(chǎn)品。它突破了一般軸承依靠油膜潤滑的局限性。在使用過程中，石墨銅套 ,銅套加石墨通過摩擦熱使固體潤滑與軸摩擦，形成油、粉末并存潤滑的優(yōu)異條件，既保護(hù)軸不磨損，又使固體潤滑特性永恒。它的硬度比一般銅套高一倍，耐磨性能也高一倍。
*使用場(chǎng)合：
目前已運(yùn)用于冶金連鑄機(jī)，列車支架、軋鋼設(shè)備、礦山機(jī)械、船舶、氣輪機(jī)等高溫、高載、低速重載等場(chǎng)合。Self-lubricating bearings, JDB - 650 belongs to a series of sliding bearing, is in the high force brass (main chemical composition Cu Al Mn Fe Ni zinc percentage respectively: 60 ~ 66% 5.0 0.2 2.5 ~ 2.5 ~ 7.5% and 5.0% ~ 7.5% ~ 0.5% 22 ~ 28%) on the base of graphite solid lubricant inlaid a high-performance solid lubricant.It broke through the general bearing on the limitations of the oil film lubrication.In use process, through the friction heat make solid lubrication and shaft friction, the excellent conditions of forming, powder and oil lubrication, both to protect shaft wear and tear, and the solid lubrication characteristics of eternity.It is twice as tall as general copper sleeve, wear-resisting performance is twice as high.
It is recommended to use occasions:
Now the product has been used in metallurgical continuous casting machine, train bracket, steel rolling equipment, mining machinery, shipping, steam turbine and other high temperature, high load, etc of low speed and heavy loading.
