Schaeffler pioneering research in extreme conditions

Schaeffler collaborates with Uppsala University for a ground-breaking project called the Arianna (Antarctic Ross Ice-Shelf Antenna Neutrino Array) to study neutrinos more closely. Neutrinos, known as Ghost particles, flow through the universe at lightning speed and scientists believe they will explain the existence of the cosmos. To track them down, ultra-sensitive detectors were set up in extreme locations in the Antarctic. Schaeffler was tasked with manufacturing bearings for the wind turbines to supply electricity for the research equipment.

With long-standing experience in special-purpose bearings, Schaeffler delivered speciality grooved ball bearings with ceramic balls. Engineered to operate without oil or grease, offering special seals for low friction and good operability at extremely low temperatures. These bearings proved to be robust, allowing the wind turbines to withstand harsh ambient conditions and reliably supply the detectors with electricity.

Prof Hans Bernhoff, Scientist at Uppsala University, stated, "We're highly pleased with Schaeffler's support and equipment. Without these speciality low-friction bearings from Schaeffler, this project would not have been possible. This collaboration has significantly contributed to the success of this research,".

Erik Askensjö, managing director of Schaeffler, shared the same sentiment saying: "We're proud of being part of this important research that clearly shows that our products are developed to satisfy even the most exacting demands".

The Arianna project will continue in even colder places in Antarctica, where the winds blow more irregularly at slower speeds, requiring larger bearings to deliver equally reliable performance with even lower friction. Schaeffler will look again to supply innovative bearing solutions to meet these requirements.
