Consisting of a stainless steel shell and a lip-turning PTFE rotary sealing lip, because of its excellent anti-friction properties, it can be used in harsh working conditions such as poor lubrication, no oil or less oil, high temperature, high-speed rotation, and strong corrosive media. Application, even if it is restarted after a long-term shutdown, it can immediately have low friction characteristics, and its dimensional tolerance standard is exactly the same as that of the rubber skeleton oil seal, which can be interchanged. The materials that our company can make include various rubber materials (NBR, FKM, FFKM, SIL, EPDM, HNBR, CI, etc.), various polyurethane materials (oil resistance, hydrolysis resistance, high temperature resistance, food grade, ultra-wear resistance, etc.), various engineering plastics (PTFE, PTFE composite, ultra-high molecular polyethylene, PA, POM, phenolic resin, etc.) and metal materials.

Parameters

The internal open type is suitable for internal positive pressure conditions. The C-ring is a typical self-sealing structure. When the medium pressure enters the C-ring in the working state, the pressure self-tightening effect is generated on the C-ring from the inside to the outside, that is, the greater the system pressure, the better the sealing effect. Due to the principle of opening and self-sealing, it is only necessary to overcome the elasticity of the sealing ring itself during installation, so a very ideal sealing effect can be obtained without using a large pre-tightening force. Our company adopts INCONEL 718 alloy to manufacture.
