Grease‑pumping radial lip seal ideally suited to large diameter wind turbine shaft sealing duties.
The Walkersele X-Gen Helix represents a new generation design within our well proven family of radial lip seals for rotating shafts and rotating plant.
Lip seals were originally designed to work with oil as a lubricant, their sealing principle relying on the sealing lip running on a thin film of oil on the surface of the shaft. In modern wind turbines however, the vast majority of bearings now use high-performance greases for lubrication, bringing a whole new dynamic to the operation of the bearing seal.
This specialised grease-pumping design is specifically optimised for the sealing of the main bearings of the very largest wind turbines and can cope with dynamic radial eccentricities of up to +/- 2 mm (1/16").
