Performance and Purpose:

Slip ring combined seal is made up of low-friction PTFE composite slip ring and O-ring. It has the advantages of friction resistance, temperature resistance, high pressure bearing ability, high linear velocity, small friction force and long use-life. And which is applicable to dynamic and static seal of hydraulic and pneumatic system in aircraft, metallurgy, petroleum, chemical, textile, food industry and so on.

由低摩擦聚四氟乙烯(PTFE)复合材料滑环与O形圈组合而成的组合密封具有耐磨、耐温、耐压、线速度高、摩擦力小和使用寿命长的特点。适用于航空、冶金、石油、化工、纺织、食品等行业的液压与气动系统的动、静密封。

Advantage

The structure is simple, easy to install and can be used repeatedly

结构简单，安装方便，可重复安装使用

The sealing performance is reliable and adjustable

密封性能可靠，密封性可调节

Different types of PTFE materials(Self pressed PTFE barrel material) can be selected according to the working conditions of sealing environment

自主压制四氟桶料，可根据密封环境工况选择不同类型四氟材料

The working life of dynamic pressure seal is 5 ~ 10 times higher than that of conventional rubber sealing products, and the highest working life can reach dozens of times

工作寿命高，动态压力密封工作寿命比常规橡胶密封制品高5~10倍，最高可达数十倍

It can be used as oil-free lubrication seal

可作无油润滑密封

The friction force is small, and the dynamic and static friction force are equal. The friction force is 1 / 2 ~ 1 / 4 of the O-type rubber ring, which can eliminate the "crawling" phenomenon of motion at low speed and low pressure.

摩擦力小，且动、静摩擦力相等，是O型橡胶圈的1/2~1/4，可消除低速低压下运动的“爬行”现象
