Shaft gasket rings

Simmer ring / gufero - radial shaft gaskets are used to seal rotating shafts, most frequently in the following designs:
  • engines for crankshaft and cam shaft sealing
  • drive shafts in passenger and utility vehicles
  • drive shafts in agricultural and construction machinery
  • industrial gearboxes
  • hydro aggregates
  • washing machines
  • other possible uses in machines and devices

  • G - seals with a seal lip
  • GP - seals with a seal lip and a duster

  • Modification
  • DL - left-hand ribbing of the sealing surface
  • DP - right-hand ribbing of the sealing surface
  • V - wave outer surface treatment

  • Rubber type
  • NBR - nitrile rubber gasket
  • MVQ - silicone rubber gasket
  • FKM - fluor-caoutchouch gasket
  • ACM - acrylic gasket
