Gumiházas rugó nélküli szimering

KC is a single action rotary shaft seal for rotating or pivoting shafts. The sealing lip design without a spring produces less friction. As a result the sealing action in comparison to rotary shaft seals with energised springs is reduced. 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 housings as well as good static sealing with thin fluid or gaseous media.

Product advantages

  • good static sealing and thermal expansion compensa­tion
  • low friction and low heat generation
  • extremely compact design
  • low radial force provides a low brake-out torque
  • suitable for scraper applications

Application

Secondary sealing e.g. as a dust, dirt or spray protection seal in electric engines, as a grease retainer. For roller bearings, tooling fixtures (e.g. drilling machines), sealing against viscous media (e.g. grease), supplementary excluders (shaft ends), axle king pin seals.

Seal housing tolerance

Ødf8/h11
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.
