The A type 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 nitrile. This broad foundation of standard O-ring and PTFE materials can be tailored to suit nearly all applications.
The most popular fillers for products are graphite, fiberglass/molybdenum disulfide, carbon fiber and mineral.
