Double/Singel PTFE Lip Rotary Shaft Ptfe Oil Seal
Radial shaft seals with one or more PTFE sealing lip(s) are designed to withstand aggressive environments, high temperatures, high pressures and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand. 
Main advantages of PTFE oil seals include:
High chemical resistance
Withstand speeds up to 30 m/s (5 900 ft/min)
Wide operating temperature range, -70 to +250 °C (-95 to +480 °F)
Withstand pressures up to 3,5 MPa (500 psi)
Withstand dry running
Assortment
The profiles shown are a selection of the most commonly used seal designs with sealing lips made of PTFE. They can be installed in existing housing grooves where traditional radial seals are used, provided that the grooves are manufactured in accordance with international standards.
PTFE materials
The selection of seal materials typically requires a compromise between advantages and disadvantages. There are hundreds of different PTFE materials with a variety of fillers. Common fillers include glass fibre, carbon, graphite, molybdenum disulphide, metal oxides and various polymers. Each possesses different properties, appropriate for different applications and service conditions. Common to all filled PTFE materials are their improved resistance to wear and deformation.
Unfilled PTFE provides, in most cases, a lower coefficient of friction than a filled PTFE material and the lowest degree of wear of the seal counterface. However, a sealing lip made of an unfilled PTFE material has limited resistance to wear and deformation under load.
