An innovative manufacturing solution from Supfina now makes the fine surface finishing of rings for large bearings possible. This results in many advantages, particularly the significant extension of bearing life.

Given the increasingly shorter development cycles for wind turbines and the parallel shortening of test phases, manufacturers are under enormous pressure. Simulations and complex models are increasingly replacing real tests, which raises the risk of failures, particularly in the main bearings. Since the main bearing is the central element of the drivetrain, the impacts of a failure are particularly severe. It is the heart of the system and must match the lifespan of the entire wind turbine. Furthermore, the ongoing trend towards larger and more powerful systems, coupled with the growing competition in the global market, increases the pressure on the industry.
