液壓氣動(dòng)密封件—AD返回 >>
概   況型號(hào)參數(shù)

AD防塵圈的作用是防止粉塵、污物、沙粒 或細(xì)屑進(jìn)入運(yùn)動(dòng)的活塞桿。它可以防止刮傷、保護(hù)導(dǎo)向零件、延長(zhǎng)密封件壽命。

AD型防塵圈是由PTFE防塵環(huán)和O形圈組成并具有預(yù)緊力。

AD防塵圈主要的優(yōu)點(diǎn)是:

?小溝槽尺寸。

?極小的起動(dòng)和運(yùn)動(dòng)摩擦力,甚至在低速下也可保證平穩(wěn)運(yùn)動(dòng),無爬行現(xiàn)象。

?極好的滑動(dòng)特點(diǎn)。

?耐磨損,使用壽命長(zhǎng)。

?溫度范圍寬(使用合適的O形圈材料)。

?極耐化學(xué)介質(zhì)(配合適當(dāng)?shù)腛形圈材料)。

?可提供最大至直徑2500mm的產(chǎn)品。

工作條件

工作溫度:-50°C至+200°C(選相應(yīng)的O形圈)

表面速度:≤4m/s
