Aerospace bearings: Key to high performance and reliability
Summary: The precision machining technology for aerospace bearings has extremely high requirements, and usually requires the use of advanced technologies such as CNC machining and ultra-precision grinding to ensure the precision and quality of the bearings.
Key Technologies of Aerospace Bearings
Material selection is crucial for aerospace bearings. Common materials include steel, ceramics, and plastics. Steel materials have good strength and wear resistance, but their high density makes them unsuitable for aerospace applications requiring lightweight designs. Ceramic materials have excellent high-temperature and corrosion resistance, meeting the high-temperature, high-speed, and high-precision requirements of aerospace, and are therefore widely used in aerospace bearings.
Lubrication Technology
Lubrication technology is key to maintaining the normal operation of aerospace bearings. Effective lubrication reduces friction, wear, and extends bearing life. In the aerospace field, common lubrication methods include dry lubrication, oil lubrication, and solid lubrication. Different lubrication methods are suitable for different working environments and requirements.
Precision Machining Technology
Aerospace bearings require extremely high precision machining technology, typically using advanced technologies such as CNC machining and ultra-precision grinding to ensure bearing accuracy and quality. Precision machining technology not only improves bearing performance but also reduces bearing friction loss, improving the overall efficiency of aerospace systems.
