氣缸原理：1）缸筒 缸筒的內(nèi)徑大小代表了氣缸輸出力的大小?；钊诟淄矁?nèi)做平穩(wěn)的往復滑動，缸筒內(nèi)表面的表面粗糙度應(yīng)達到Ra0.8um。對鋼管缸筒，內(nèi)表面還應(yīng)鍍硬鉻，以減小摩擦阻力和磨損，并能防止銹蝕。缸筒材質(zhì)除使用高碳鋼管外，還是用高強度鋁合金和黃銅。小型氣缸有使用不銹鋼管的。帶磁性開關(guān)的氣缸或在耐腐蝕環(huán)境中使用的氣缸，缸筒應(yīng)使用不銹鋼、鋁合金或黃銅等材質(zhì)。
　　氣缸活塞上采用組合密封圈實現(xiàn)雙向密封，活塞與活塞桿用壓鉚鏈接，不用螺母。
　2）端蓋 端蓋上設(shè)有進排氣通口，有的還在端蓋內(nèi)設(shè)有緩沖機構(gòu)。桿側(cè)端蓋上設(shè)有密封圈和防塵圈，以防止從活塞桿處向外漏氣和防止外部灰塵混入缸內(nèi)。桿側(cè)端蓋上設(shè)有導向套，以提高氣缸的導向精度，承受活塞桿上少量的橫向負載，減小活塞桿伸出時的下彎量，延長氣缸使用壽命。導向套通常使用燒結(jié)含油合金、前傾銅鑄件。端蓋過去常用可鍛鑄鐵，現(xiàn)在為減輕重量并防銹，常使用鋁合金壓鑄，微型缸有使用黃銅材料的。
　3）活塞 活塞是氣缸中的受壓力零件。為防止活塞左右兩腔相互竄氣，設(shè)有活塞密封圈?；钊系哪湍キh(huán)可提高氣缸的導向性，減少活塞密封圈的磨耗，減少摩擦阻力。耐磨環(huán)長使用聚氨酯、聚四氟乙烯、夾布合成樹脂等材料?；钊膶挾扔擅芊馊Τ叽绾捅匾幕瑒硬糠珠L度來決定?；瑒硬糠痔?，易引起早期磨損和卡死?；钊牟馁|(zhì)常用鋁合金和鑄鐵，小型缸的活塞有黃銅制成的。
　4）活塞桿 活塞桿是氣缸中zui重要的受力零件。通常使用高碳鋼，表面經(jīng)鍍硬鉻處理，或使用不銹鋼，以防腐蝕，并提高密封圈的耐磨性。
　5）密封圈 回轉(zhuǎn)或往復運動處的部件密封稱為動密封，靜止件部分的密封稱為靜密封。
缸筒與端蓋的連接方法主要有以下幾種：
　　整體型、鉚接型、螺紋聯(lián)接型、法蘭型、拉桿型。
　6）氣缸工作時要靠壓縮空氣中的油霧對活塞進行潤滑。也有小部分免潤滑氣                                       費斯托部分產(chǎn)品型號：LFMBA-1/2-D-MAXI-A
