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 are not only used in automobiles, but also in various machines, such as
  • Trains
  • Airplane
  • Washing machine
  • Refrigerator
  • Air conditioner
  • Vacuum Cleaner
  • Photocopiers
  • Computer
  • Satellite
Bearing Introduction

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.

Rolling bearing Introduction

  • Rolling bearings consist of four elements and have an extremely simple basic structure.
  • Outer ring: Large outer ring
  • Inner circle: Inner circle small circle
  • Rolling body: Several balls or rollers contained in the space between the outer and inner rings
  • Cage: Used to hold the rolling body in place

Bearing Introduction Function

  • The basic function of a bearing is primarily to reduce mechanical friction. Reduced friction means:
  • More efficient machine operation
  • Less frictional wear and longer mechanical life
  • Prevention of wear and tear burns and mechanical failures
  • Bearings can also reduce energy consumption by reducing friction and enabling efficient power transmission.
  • This is just one way in which bearings are environmentally friendly.

Bearing Introduction Type

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.
