Wind Turbine Bearings: Day 1 - 27/08/2025

10:00 - 10:15 Chairperson’s opening

10:15 - 10:45 Keynote: Scalability limits for Wind turbine architecture, and its affection to main bearings.

Daniel Román Barriopedro - Product Architecture Head, Siemens Gamesa Renewable Energy
  • Main upscaling limitations.
  • Different solutions adopted by WTG OEMS to overcome those limitations.
  • Forecasted evolution of main components and bearings sizes (focused on Geared WTGs).
  • Potential affections to bearings OEMS.

15:30 - 16:30 Refreshment Break and Networking

  • The SJB™ can be integrated within the design space of existing roller bearing solutions. This can extend the lifecycle of existing products or renewed life for older turbines. 
  • Less number of components reduce failure probabilities and equally distributed load on rotating segment improve the lifetime. 
  • The bearing materials have been tested thoroughly in wind turbine gearboxes for several years.
  • The system can be design more compact or can increases the power density in existing space.
  • Lower noise production and dampening due to hydrodynamic lubrication

17:00 - 17:15 Chairperson’s closing remarks

19:00 - 19:00 Evening Get-Together

Join us for an informal evening get together at Emma am See where some refreshing drinks and a nice barbecue buffet will be waiting for you! You are not only visiting an architecturally award-winning monument, but meeting your peers in a relaxed atmosphere, exchanging business cards. and reviewing the first conference day.
