Due to their elastomer sealing lip,
standard radial shaft seals have only a limited application
range with respect to pressure , temperature and media loads.
High performans sealing lips made from modified
PTFE , cause very low friction , thanks to their stick-slip-free
running , suffer little wear and tear, reducing the heat development
and permitting higher peripheral speeds.
Advantages of PTFE seals are :
· Low friction seal material
· Low and high temperature range (-60 to +260 șC
· High pressure capability (up to 25 bar )
· High speed ability ( 40 m/s )
· Outstanding resistance to chemical media
· Fits Standard oil seal installation groove.
