Schaeffler ranks among the world's leading manufacturers of rolling bearings. As a development partner for the sector we have been producing bearing supports for wind turbines for over 30 years. We offer the right bearing solution for every wind turbine and an integrated concept for safety.
With our INA and FAG brands, we offer the right bearing solution for rotor shafts, gearboxes, generators, and nacelle and blade adjustment. Special greases, services and products for all aspects of maintenance and condition monitoring round out our programme.
Cost-effective wind turbines require reliable components. We offer an integrated concept for safety.
This standard for products and processes means Schaeffler is ensuring outstanding quality and reliability, and is offering the same high standards of quality as it is already successfully offering in the automotive and aerospace industries.
Our specialists work closely with designers, manufacturers and operators of wind turbines. This has resulted in unbeatable know-how: detailed attention is paid to customer requirements already at the concept phase. State-of-the-art calculation and simulation programmes ensure optimal designs for bearings for wind power applications are produced. The entire system is considered starting from a single rolling bearing and its components, the adjacent construction up to the entire power transmission system, which is displayed and optimised using multi-body simulation programmes developed in-house.
One of the most modern, largest and highest-performing large-size bearing test rigs in the world, enables bearings of up to 15t and measuring up to 3.5m to be tested. Astraios simulates the real loads and moments that occur in a wind turbine. This means we are making a major contribution to shortening development times for wind turbines as well as making the design process more reliable and increasing the cost-effectiveness and safety of these turbines.
Schaeffler has comprehensive testing facilities for creating white etching cracks (WEC), analysing the causes and developing solution concepts for reducing the risk of WEC.
The solution that Schaeffler recommends is to use through hardened bearings with black oxide coating. The advantages that our Durotect B coating system offers include increased protection against WEC, which has been statistically verified by extensive experience in the field. In the last 13 years, the failure rate due to WEC for 1,000,000 bearings with black oxide or Durotect B coating that have been produced and delivered by Schaeffler for use in wind turbines has been less than 0.01%.
We offer products and services for all aspects of condition monitoring, e.g. remote monitoring and diagnosis, offline measurements, endoscopy, thermography and speed measurement. Thus maintenance operation costs can be reduced and the availability of wind turbines can be increased. Digitalisation makes entirely new solutions possible in the field of maintenance services. With predictive maintenance, we are expanding conventional condition monitoring approaches by allowing users to look into the "turbine's future" and thus opening up new possibilities for increasing efficiency and reducing the total cost of ownership (TCO).
