材料組織 MATERIAL STRUCTURE

SF-1P往復(fù)運(yùn)動(dòng)軸承是在SF-1材料的結(jié)構(gòu)基礎(chǔ)上，根據(jù)往復(fù)運(yùn)動(dòng)的特殊工作條件而設(shè)計(jì)的新穎配方產(chǎn)品，其性能與國(guó)外DD2相似。

主要參數(shù) TECHNICAL DATE

最大承載	低速運(yùn)轉(zhuǎn)	140N/mm2	最大線(xiàn)速度	干摩擦	2m/s
	旋轉(zhuǎn)、搖擺運(yùn)動(dòng)	60N/mm2		流體潤(rùn)滑	5m/s
最大PV值 (干摩擦)	間斷性運(yùn)作	3.6N/mm2.m/s	導(dǎo)熱系數(shù)		42W(m.K)-1
	長(zhǎng)期運(yùn)作	1.8N/mm2.m/s	線(xiàn)膨脹系數(shù)		11x11-6K
使用溫度		-195℃~＋280℃

應(yīng)用特點(diǎn) APPLICATION CHARACTER

1.具有在新油情況下潤(rùn)滑能力強(qiáng)，耐磨性好，保護(hù)的優(yōu)點(diǎn)。
2.能較好的保護(hù)對(duì)軸表面的不受磨損。
3.對(duì)往復(fù)運(yùn)動(dòng)場(chǎng)合較能適用
4.產(chǎn)品適用于摩托車(chē)減震器，各種液壓油缸、液壓馬達(dá)、氣動(dòng)元件等
