Novel bearing steel
08 December 2025
SKF CONTINUES to re-imagine intelligent and clean rotation with the development of an innovative temperature-resistant, corrosion-tolerant steel for aeroengine bearings called ARCTIC15.

With the Aerospace industry striving to reach net zero emissions by 2050, next generation jet engine designs are evolvingtowardgroundbreaking architectures which require rolling bearings capable of higher power density and speeds beyond the current design rules.
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 willenable 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.
