How Do The PTFE Rotary Seals Work?
Oct 26, 2022
PTFE lip seals typically serve two purposes: keeping the bearing or system lubricated and excluding contaminants that could damage the system or bearing. The operation of the seals in preserving the bearing or system lubrication is critical for the entire equipment or machine to function, which means the seals directly determine the service life of the facilities or devices. Our PTFE rotating lip seals have excellent operating characteristics, allowing them to bridge the gap between current gas and liquid sealing technologies.
PTFE Lip Sealing Materials
Although there are hundreds of distinct PTFE materials with various fillers, graphite, fiberglass, molybdenum disulfide (MoS2), carbon fiber, and mineral are arguably the most well-known fillers.

Features & Benefits of Rotary Lip Seals
1. Low friction. PTFE rotary seal features very minimal friction coefficients in contrast to any solid material.
2. Chemically inert. PTFE comprises carbon-fluorine bonds that are non-reactive, that causes it to can’t break down from exposure to chemicals.
3. High-pressure resistance. This feature makes the PTFE lip seals such valuable in applications with heavy-duty machinery.
4. Chemical compatibility. PTFE lip seals can be used with a variety of media, including synthetic lubricants, heat transfer oils, glue, steam, chemical wastewater, etc.
5. Wide operational temperature range. The lowest temperature PTFE seals can operate at is – 80°C, and the highest temperature is up to 200°C.
6. Excellent performance in dry or abrasive media. The rotary lip seals perform exceptionally well concerning friction and stick-slip running.
7. High RPMs functionality. PTFE lip seal is a lot better than rubber seals within a significantly wider assortment of rotating rates and diameters.
