OS-PA31


Description


  • Pressure loadable radial shaft seal
  • Metal OD
  • Sealing lip made of PTFE
  • Sealing lip with elastomer washer, clamped between 2 metal cases


Special features


  • Permits high shaft speeds
  • High thermal resistance
  • High chemical resistance
  • Pressure loadable
  • Applicable with insuffi cient lubrication and dry running
  • Very low friction coefficient, stick-slip free running 
  • Non-moulded processing
  • Inside diameter from 31mm possible
  • Small runs without mould cost possible
  • Short delivery time
  • Very fi rm and exact fi t inside the housing due to metal-metal interference fit
  • 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


Applications e.g.:


  • Chemical industry
  • Mechanical and apparatus engineering
  • Drive systems
