Description
Single lip PTFE oil seals, low friction, suitable for windmill,pump,compressor,gearbox,engine bearing and other applications. It is a rotary lip seal that features an ID lip that seals dynamically on a shaft and an elastomeric O-ring on its OD to seal statically in a bore. Since the lip is not spring energized, the radial lip contact forces are lower than a rotary metal lip seal, which allows the seal to function at much higher surface speeds (up to 30m/s).
The seals are manufactured from a wide variety of PTFE composites and other machinable plastic materials. Standard O-ring choices are NBR. This broad foundation of standard O-ring and PTFE materials can be tailored to suit nearly all applications. PTFE rotary oil seal 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.
