Bearing Introduction of structure and function.
DERUNA has made a significant contribution to the development and advancement of various industries that depend on machinery. As a comprehensive bearing manufacturer, DERUNA responds to the needs of a wide range of fields.
A staggering number of bearings can be found all around us. Take an automobile, for example: an average car has 100 to 150 bearings. Without bearings, the wheels would rattle, the transmission gears would not engage, and the car would not run smoothly.
Bearings enhance the functionality of machinery and help save energy. Bearings work silently in harsh environments, hidden from our view in machines. However, bearings are vital to the stable operation of machinery and to ensure its optimal performance.
Anything that can be called a machine inevitably contains bearings. Bearings must meet a wide variety of needs, and they will continue to evolve to do so.
