Emerging Trends Shaping the Aerospace Bearings Industry
Companies leading the aerospace bearings market are prioritizing innovation, particularly in the development of turbine generator bearings designed to boost efficiency and reliability in aerospace applications. These specialized bearings support the rotating parts of turbine generators, which are critical components in aviation and industrial settings. For example, in April 2024, NSK Ltd., a Japan-based manufacturer, introduced a new gas turbine generator bearing tailored for electric vertical take-off and landing (eVTOL) aircraft, including large drones. This bearing incorporates a unique lubrication mechanism that cuts lubricant requirements by nearly 80%, contributing to extended flight ranges for eVTOLs. It offers high-speed rotational performance surpassing 2.5 million dmn while reducing power loss by about 30% compared to conventional jet lubrication systems. Moreover, this design enables the use of smaller oil pumps and lubricant tanks, further enhancing operational efficiency for eVTOL platforms.
