OS-B11

Description

  • Metal OD
  • Spring loaded sealing lip
  • Protective lip against entry of contamination from outside (dust, dirt,...)


Special features

  • Modern sealing lip design for high dynamic sealing action
  • Very firm and exact fit 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. A version with outside diameter coated with bore sealant is available on request
  • Can be combined with our axial seals AS-10 and V-rings
  • Efficient protection against air side contaminations


Applications e.g.:

  • Mechanical and apparatus engineering
  • Agricultural machinery
  • Construction machines
  • Drive systems, industrial gearboxes, electric motors
