Plastic bearing function: the original may take the plastic bearing, usually divides into the plastic rotating bearing then has is the plastic sliding bearing. Based on the name may be plastic bearings such a bearing, and then the basic principles of plastic sliding bearings such a bearing out, then what is the difference? (1) what is to be introduced here is that plastic bearings such bearings, in the case of the bearing at the beginning of the work, the friction generated belongs to the type of friction, and plastic sliding bearings such bearings, in the case of its operation, the type of friction produced is sliding friction type. (2) in the case of rotational friction, the magnitude is also largely determined by the correct level of the production premise or aspect. However, the plastic sliding bearing friction in this respect, the plastic sliding bearing friction is basically in the bearing sliding to save information to depend on. (3) It is worth mentioning that in the plastic rotating bearing working surface, plastic rotating bearing working surface, most of the basic function is with self-lubrication. Plastic sliding bearing is also a major part of the work is to take part in the function of this area, has a good quality of engineering plastics to manufacture molding. Compared with the professional manufacturers, these are mostly with the engineering plastics existing in the active lubrication of the improved use of functional skills, in engineering plastics quality, it is possible to start with an emphasis on active lubrication, strengthening renewal, reforming the use of function, in terms of fibre data, special types of lubricants, glass balls, etc. . The goal is to potentially improve the absolute level of the consequences, and then to transform functional plastics, such as injection molding, into actively lubricated plastic bearings. In today's polymer plastic sliding bearings, in the application of this bearing, the absolute level is usually the series of CSB-EPB plastic sliding bearings. Classification and characteristics of plastic bearings 1. Refined plastic bearings: refined plastic bearings than the traditional plastic bearings to improve the precision and dimensional tolerance. Plastic bearings can generally be divided into plastic rolling bearings and plastic sliding bearings; the working principle of plastic rolling bearings and plastic sliding bearings can be distinguished by their names, the friction of plastic rolling bearing is rolling friction, and that of plastic rolling bearing is sliding friction, and the rolling friction depends on the manufacturing precision The friction force of plastic sliding bearing mainly depends on the material of sliding surface. Refined plastic bearings overall selection for the refined processing of the information system inside and outside the ring, rotating body and adhere to the frame, etc. , in adhering to some of the traditional advantages of plastic bearings, basically, may Be applied to these delicate and relatively high-speed operation and other extreme operating conditions standard. Individual inner and outer rings are made of Pom, PPS, or PEEK, rigid frame is made of glass fiber reinforced Nylon 66(RPA66-25) , or PEEK, rotating body is made of glass ball, stainless steel ball or ceramic ball. 2. Corrosion resistant plastic bearings: Corrosion resistant plastic bearings may operate even in the most atrocious acid/alkali/salt/solvent/oil/gas/sea water erosion with a solution based on a variety of information for those different use cases, guarantee the durability of the fantasy and the expected lifetime. ACID-AND ALKALI-RESISTANT PLASTIC BEARINGS: acid-and alkali-resistant plastic bearings, HDP E, UHMWPE and other materials have been proved to be possible to be used as absolutely weak acid-and alkali-resistant cross-over environment (30% CuCl2 solution and 30% naoh solution test OK) , pVDF and PTFE data may be used in strong acid and alkali environments. PTFE data may be used in all strong acid and alkali environments, even HF and strong acid environments such as fuming nitric acid (above 98%) . High temperature resistant plastic bearings: high temperature resistant plastic bearings, pVD F, PTFE , PPS (poly(p-phenylene sulfide)) , PEEK (polyether ether ketone) , Pi (polyether imide) and so on have all proved to be some fantastic materials for manufacturing high temperature plastic bearings, in this kind of material, Pi can be used in the environment of 290 °C for a long time, and the short-term high temperature resistance can be as high as 350 °C. Stainless steel bearings and ordinary bearings, not only the material has obvious advantages, but also in the process, precision control, than ordinary bearings to be much more stringent. In the working process of stainless steel bearings stable work, low noise, corrosion-resistant, widely used. Ceramic Ball Dry isostatic press do ball low-temperature pre-firing, spheronization, high-temperature sintering, grinding but recently learned to do first precision, or high-temperature hardness after firing. Plastic bearing housings and plastic outer spherical bearings: Plastic bearing with a seat does not have other plastic bearing functions, such as light weight, simple device, corrosion resistance, free from maintenance, etc. , at the same time also has the common cast iron seat or punching seat does not have the shock absorption characteristics of energy. Because of the continuous development of a variety of new plastic materials, such bearings are increasingly used in a variety of engineering applications.
