TG552型 桿用組合密封
一、標(biāo)準(zhǔn)材料
雙三角密封環(huán)：填充PTFE，T101；
O型圈：丁腈橡膠、三元乙丙或氟橡膠。
二、概述
TG552型活塞桿用組合密封由一個(gè)填充聚四氟乙烯材料的雙三角密封環(huán)和一個(gè)GB1235 “O”形橡膠圈組合而成。適用于液壓與氣動(dòng)往復(fù)運(yùn)動(dòng)活塞桿密封，起雙向作用。推薦用于輕載液壓元件中，如機(jī)床、閥門、物流設(shè)備等。
設(shè)計(jì)選用時(shí)可參考NOK公司SPNC系列標(biāo)準(zhǔn)。
三、特點(diǎn)
*耐磨損，耐擠出
*摩擦力小，無(wú)爬行
*緊湊的溝槽尺寸，結(jié)構(gòu)簡(jiǎn)單
