Walksersele® X‑Gen D10

Radial lip seal ideally suited to large diameter wind turbine shaft sealing duties.

TYPICAL APPLICATIONS
  • Large diameter turbines
  • Wind

The D10 Walkersele represents a new generation patented design within our well proven family of radial lip seals for rotating shafts and rotating plant. This specialised fingerspring energised 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 +/- 3 mm (1/8").

  • Fingerspring design achieves consistent lip load at even the largest diameters and makes installation simpler than other spring options
  • Long term fatigue testing shows consistent response even at high speed, ensuring the sealing lip remains in contact with the sealing surface at all times
  • Validated to operate at dynamic radial eccentricities of up to +/- 3mm (1/8”) at surface speeds of up to 2 m/s
  • Fingerspring design provides optimal lip load to reduce torque, under lip temperature, and wear
  • Available in endless or Walkersele OSJ-D format for on-site joining to radically reduce seal change-out costs and downtime
  • UK Patented design 2562205

  • Main bearings on large diameter wind turbines
  • Yaw/slew bearings on large diameter wind turbines

  • Mineral and synthetic oils
  • Water
  • Mineral and synthetic greases

  • Temperature: -30°C to +150°C (-22°F to +302°F) dependent on material choice
  • Pressure: pressure differential of up to 50 kPa / 0.5 bar (7 psi)
  • Surface speed: 2.6 m/s (512 fpm) dependent on material choice
  • Please contact us for operating conditions outside these parameters
