Aircraft bearings play a critical role in sustaining safe and efficient operations, as they have the capacity to support heavy loads while minimizing friction between moving components. To function reliably under the demanding conditions of flight, they are commonly engineered with specific structural designs, specialized materials, and tailored service procedures in mind. In this blog, we will explore the primary categories of bearings used in aircraft, cover notable materials that are selected for their construction, and discuss various maintenance practices that can preserve their long-term performance.
