Plastic sliding bearings are generally made of engineering plastics with better performance. The plastic bearings used can generally be divided into plastic rolling bearings and plastic sliding bearings; the working principles of plastic rolling bearings and plastic sliding bearings can be distinguished by their names. The friction that occurs when plastic rolling bearings work is rolling friction, and when plastic sliding bearings work What occurs is sliding friction; the size of rolling friction mainly depends on the manufacturing accuracy; and the size of plastic sliding bearing friction mainly depends on the material of the bearing sliding surface.

Uses of plastic bearings: mechanical and electrical equipment, fitness equipment, food machinery, furniture and decoration and building materials
