OS-C13

Description

  • Metal OD + reinforcement cap
  • Non-spring-loaded sealing lip
  • Protective lip against entry of contamination from outside (Dust, dirt,...)


Special features

  • Non-spring-loaded lip design for secondary sealing jobs e.g., grease sealing
  • Low friction
  • Compact design
  • Little installation space
  • Firm and exact fi t inside the housing
  • Be careful when using the product in connection with light metal housings, housings with increased surface roughness and applications with overpressure: Apply sealing aid to the outside diameter if necessary. A version with outside diameter coated with bore sealant is available on request
  • Effi cient protection against air side contaminations


Applications e.g.:

  • Secondary sealing jobs
  • Mechanical and apparatus engineering
  • Drive systems
  • Electric motors
