V型端面水封GRM/GRME

1.特点

旋转端面用纯胶密封,防止外界的灰尘、粉末、水及它们的混合物和油脂等

进入轴承或密封系统。可用于大部分轴承中,并且可以作为副密封用于主密封容

易失效的恶劣环境中。

2.材料

一般情况下选用丁腈橡胶NBR;在使用温度高于100

°C,

或者极端耐化学介

质的情况下,选用氟橡胶FKM。

3.性能

安装方便,可以正常拉伸并依靠橡胶本身的弹性使其紧包在旋转轴上;

唇口接触压力小,并且接触压力随线速度的增加而降低,耐磨性好;

允许一定程度的轴偏心;

有效防止灰尘、粉末、水、油脂等的侵入。

4.工况条件(以下极限数值不可同时出现)

速度:≤15m/s(取决于橡胶的材质)

温度:-35~180

°C

(取决于橡胶的材质)

介质:水、灰尘、粉末、油脂等。

5、钢带安装和使用
