Mechanical Face Seals

Mechanical Face Seals are also known a Lifetime Seals, Metal-Face Seals or Floating Seals. They are employed in industrial machinery exposed to areas of high contamination by dust, sand, mud, minerals and earth. Those seals also are ideal for application within the most extreme weather conditions from -49° C do +250° C.

We provide mechanical face seals in diameters from ∅38mm up to do ∅1000mm.
They are available in the following the material versions:

  • Steel, hardness  HRC 58-62
  • Cast iron, hardness  HRC 62-68
  • Hardened cast iron, Duronit V harness  HRC 60
