OS-BG11

Description

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


Special features

  • Combines the advantages of metal and elastomer OD:
  • Very fi rm and exact fi t inside the housing due to metal-metal interference fi t
  • Reliable static sealing inside housing
  • Compensation of diff erent thermal expansion
  • Modern sealing lip design for high dynamic sealing action
  • Effi cient protection against air side contaminations


Applications e.g.:

  • Mechanical engineering
  • Machine tools
  • Drive systems

Application parameters

For the standard materials combination

Temperature  -40°C to +100°C                                                                                           
Pressure depressurized, max. 0.05 MPa
Shaft speed acc. to chart in „Operating parameters for rotary shaft seals“
Media Mineral oil based lubricants, synthetic lubricants


When synthetic lubricants are used for which there is no empirical experience, test the compatibility in the laboratory or - better even - in practical trials. The operating temperature should not exceed 80°C.
