SKF's customers are designing new engines that aim to cut fuel use by 20 to 25%*, which also reduces emissions. To support these new designs, SKFs new steel will enable bearing solutions that can support the development of new architectures of engines for aviation.

"As aviation moves toward designing engines that aim to cut fuel consumption by up to 25%, reducing emissions significantly, SKF is innovating to match that ambition. Our new steel alloy ARCTIC15 is engineered as a breakthrough material to allow for smaller, more compact bearing solutions that handle higher loads, unlocking new engine architectures and driving efficiency across the entire lifecycle, with repairability as a key driver. This novel steel enables faster development cycles and supports industry sustainability goals for the future," says Gregory A Zimmerman, Director of Aerospace Business Unit at SKF. 

For such performance increase, the first step is made by replacing steel rolling elements with ceramic rolling elements. The second step comes by pairing ceramic rolling elements with an advanced aeroengine bearing steel with higher load and temperature capacity than existing steels. These distinctive properties open the door to new engine architectures with enhanced efficiency.

"With cross-functional collaboration and sustainability-driven programs aligned with global megatrends and industry needs, we are actively driving the climate transition. As both a supplier and customer, we transform deep insights into smart, practical solutions that reduce friction, cut emissions, and extend equipment life-helping industries move toward more sustainable operations", says Hans Landin, President, Specialized Industrial Solutions.

The new patented steel technology will be commercially available and shared by SKF at the Patent Bay. A new platform open to companies that aim to accelerate technologies with the potential to advance sustainability, by making selected patents freely available to others. 

The following sparked the development of ARCTIC15

Disclaimer
Up to 25% emission reduction
The improved fuel efficiency is enabled by a range of innovations and collaborations-one of which is Arctic15's contribution to a more optimized engine architecture.

The stated emission reduction refers exclusively to the engine's fuel efficiency improvements. It does not reflect a full lifecycle assessment of a future aircraft.
