Radial-shaft sealing ring

The Merkel Radiamatic R 55 radial-shaft sealing ring has an integrated deflector lip that protects wind-turbine systems against harsh environments and eliminates the need for a second seal. The seal does not require functional compromises and can even offset radial play or shaft eccentricity without neglecting its sealing and deflecting functions.

The R 55’s deflecting and sealing lips always stay in contact with the shaft and provide protection and leak protection. In addition, the sealing lip maintains linear contact in the event of positive shaft deflection, thus contributing to a long service life.
