✦ Synopsis

move relative to each other, a very small amount of PTFE is transferred to the surface of the shafi, which fills in microscopic surface irregularities and establishes an ideal running surface. This results in an efficient and durable sealing performance.

The seal design allows controlled lip forces, which withstand high pressures and shaft speeds, as well as dry running capabilities. In fact this type of seal can be run at speeds of up to 17 500 rpm or 70 m/s.
