With the advancement and development of science and technology, engineering plastics with low density, corrosion resistance, wear resistance, self-lubrication have become the main raw materials for making bearings, the output of plastic bearings is increasing, the scope of application is expanding, from fitness equipment to office equipment and the automotive industry can see the figure of plastic bearings, market demand has maintained rapid growth. The future is promising.
The working principle of plastic rolling bearings and plastic plain bearings can be distinguished by the name.
The friction that occurs when plastic rolling bearings work is rolling friction, while the friction that occurs when plastic plain bearings work is sliding friction; The size of rolling friction mainly depends on the manufacturing accuracy, while the friction of plastic sliding bearings mainly depends on the material of the bearing sliding surface.
