橡胶O型密封圈生产厂家圈规格大全
O型圈是一种截面为圆形的橡胶圈，因其截面为O型，故称其为O型圈。
液压与气压传动系统中使用最广泛的一种。
通常在台企、日企叫做O-Ring.O型密封圈是具有圆形截面的环行橡胶密封圈.静态条件下，O型密封圈能防止液体和气体介质的泄露.动态条件下，O型密封圈也能用作轴向往复运动和低速旋转运动的动态密封元件.根据不同的条件,可分别选择不同的材料与之相适应。
规格描述
1/一般规格表示为:
内径d1×线径d2，比如:
O形圈25*2.2，其中25代表O形圈内径为25毫米，2.2代表O形圈的截面直径是2.2毫米;2/规格齐全---有3000副模具，包括各国标准与非标，真正意义上做到了规格齐全。
一、O型圈有多长的使用寿命
O型圈的使用寿命主要是由O型圈的材质和使用环境（温度、压力、介质等）决定的。
O型圈按材质分主要为:
丁腈橡胶O型圈、氟橡胶O型圈、硅橡胶O型圈、三元乙丙橡胶O型圈、氯丁橡胶O型圈、天然橡胶O型圈等。
静态O型圈密封的使用寿命明显比动态O型圈密封的使用寿命要长的多，因为有的O型圈是套在轴上需要滑动或旋转密封的，这时O型圈的使用寿命就是由与o型圈相配合的槽及孔的配合尺寸和表面粗糙度等因素决定。
因此，O型圈的使用寿命很难给出确切的年限，使用不当O型圈的使用寿命可能1年或更低，使用妥当，O型圈的使用寿命可能是3年、6年或更高。
二、O型圈硬度的选择
O型圈硬度的选择是O型圈使用中比较重要的一环。
O型圈硬度低，便于O型圈安装，但如果O型圈硬度过于偏低，则容易出现O型圈剥落、安装损伤和挤出等不良状况;若O型圈硬度过高，则不易于O型圈的安装。
通常O型圈硬度为40,90度（邵氏硬度），在使用中O型圈一般选用70度是比较合适的，但对于硅橡胶O型圈是个例外，一般使用60度即可。
具体O型圈硬度选用时，需综合考虑O型圈实际使用的环境条件。
