Radiamatic R 55

Merkel Radiamatic R 55 is a radial shaft seal consiting of 
a fabric reinforced section of sturdy design, firmly bonded to the rubber sealing lip. A helical tension spring assists radial contact pressure of the lip on the shaft. 

In order to protect the sealing lip against dirt ingress from the outside, a functionally decoupled deflector lip has been integrated.

Merkel Radiamatic R 55 are mainly used as radial shaft 
seals for the main bearing in wind turbines.

Values to customer:

  • Integrated deflector lip instead of a secondary seal

  • Reduced housing space - easy handling

  • High shaft offsets possible due to special, non-interfering design of sealing and deflector lip

  • High wear resistance and functionally aligned sealing and deflector lip for long performance

  • Large diameter range (approx. 1000 mm up to 3000 mm) without mold cost
