Depending on the ambient and operating temperature of the face seal, the O-rings or trapezoidal rings can be made from a choice of four proven basic elastomeric materials in different grades. Each elastomeric material is highly resilient and will show very little permanent set which ensures a reliable static seal and clamping action.
NBR – standard
HNBR – higher temperatures
VMQ(silicone rubber) – covers temperature in both hot and cold extremes
FPM(Fluorine rubber) – extends the maximum temperature while offering excellent oil compatibility
To harvest the desired return on investment, the heavy equipment needs to run continuously and without costly breakdowns and unforeseen repair work.Our face seals'long service life is due to the use of chilled cast iron.This class of materials is very hard, resists abrasive wear and corrosion, and has excellent tribological properties.From the first contact with our customers to shipping the finished face seal we take full responsibility.
