DC rotary shaft seal is used for the separation of two media or extreme dirt accumulation from the outside for rotating or pivoting shafts. The DC is a double action rotary shaft ring for rotating or pivoting shafts. The elastomer outer sheath provides good static sealing, good thermal expansion balance e.g. in light-metal housings, better sealing with greater roughness and secure sealing for split housing as well as good static sealing with thin fluid or gaseous media. To guarantee high static sesling on the outer surface, better surface treatment of the housing bore is necessary or an additional coat of paint should be applied to the outer casing.

Product advantages

  • small housing
  • sealing for the separation of two media
  • two spring-loaded sealing lips (one spring-loaded dust lip against moderate to medium dust and dirt ingress)
  • reliable sealing of the housing bore, even with increa­sed roughness of the bore, thermal expansion and split housings.

Application

 Sealing of rotating machine elements such as shafts, hubs and axles. particularly for the separation of two media or extreme dirt accumulation from the outside machine tools, power take-off gears in agricultural and construction machinery transmissions and axles.

ØDH8

Installation

Suitable tool should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support.
