材料介紹
Kintowe DF310 旋轉(zhuǎn)壓力封應(yīng)用于液壓回轉(zhuǎn)接頭。該密封圈由含碳的 PTFE 密封環(huán)及丁腈橡膠的 O 形圈組成。對于腐蝕性介質(zhì)的環(huán)境也可替換成性能更好的氟橡膠材質(zhì)的 O 形圈。表面材質(zhì)和設(shè)計使得該產(chǎn)品具有高耐磨性和低摩擦的效果，能在較慢的旋轉(zhuǎn)條件下無爬行現(xiàn)象。滑動面上的溝槽形成蓄油槽。可以改善并降低摩擦。同時，它也可以減少旋轉(zhuǎn)面的接觸面積，并允許更高的接觸壓力。
該產(chǎn)品表面環(huán)與 O 形圈接觸面設(shè)計有圓弧槽，增大了與O 形圈的接觸面，最大程度地降低了密封組合部件相互間旋轉(zhuǎn)的可能性。
產(chǎn)品優(yōu)勢
● 耐高溫
● 低磨損，超低摩擦
