材料介紹
- Kintowe DF335是加強(qiáng)型雙唇防塵圈，用于防止灰塵進(jìn)入油缸，并阻止通過密封件的油漏出。
該防塵產(chǎn)品的標(biāo)準(zhǔn)設(shè)計(jì)是用青銅粉填充的PTFE材料制成，由丁腈橡膠制成的O形圈施力。另外可提供多種其他材料的選擇，以擴(kuò)大使用范圍。
產(chǎn)品優(yōu)勢(shì)
● 低摩擦，避免爬行現(xiàn)象發(fā)生
● 優(yōu)異的PTFE防塵圈
● 保護(hù)主密封免受污染
● 延長(zhǎng)密封件使用壽命
● 多種材料、尺寸型號(hào)可供選擇，以適用于特俗工況應(yīng)用
