There are various types of aircraft bearings. Recently, in response to customers' demands for reducing weight, minimizing environmental pollution, and achieving high performance in bearings, bearing systems have become more complex and require higher reliability and quality control. Design theory and industry development trend of main shaft bearings for jet engines. With the rapid development of emerging markets and the global expansion of low-cost airlines, the demand and sales of commercial aircraft have steadily increased. We provide various solutions for customers in the aerospace industry worldwide, including bearings, seals, rods, struts, precision elastic equipment, and electrokinetic control equipment for aircraft bodies, aircraft engines, and gearboxes. Ceramic bearings can operate in harsh environments with high temperatures and poor lubrication. Elastic seals and devices protect bearings or various other applications, such as rotating discs, gearboxes We have a wide range of aerospace solutions that can be applied to even heavily polluted environments, combined with the visual control or maintenance free requirements you need, to provide you with more suitable solutions. Energy efficiency is beneficial for customers in reducing the weight of aircraft, decreasing fuel consumption, and increasing payload. This is a major component of operational cost-effectiveness. Helping aircraft designers reduce the weight of multiple systems and subsystems, thereby reducing fuel consumption. In addition to reducing fuel consumption, the weight reduction solutions we provide also help increase payload, extend flight range, and lower overall operating costs; At the same time, it does not affect safety and performance. These solutions are now being applied to certain demanding aircraft, greatly reducing the costs for airlines. Combining various functions significantly reduces the number of components used globally, thereby reducing weight and saving packaging. Therefore, by improving existing applications, support can be provided for manufacturing more sustainable aircraft. Lightweight by reducing the number of global application equipment components, replacing hydraulic systems with wire control systems, developing methods for using lightweight materials, aerospace technology helps to reduce weight, and manufacture more sustainable solutions.
