Thrust ball plastic bearing 51206 pom Xingruida flat plastic bearing supplier

Advantages of plastic bearings 1, plastic bearings as a whole are lubrication data, the use of long term. 2, the use of plastic bearings will not rust and corrosion-resistant, and metal materials bearing easy to rust can not be used in chemical fluids. 3. Plastic bearings are lighter in quality than metal materials, making them more practical for the lightweight design trends of antiquity. 4, the plastic bearing manufacturing cost is lower than the metal material class; plastic bearing is selected for injection molding production processing and is absolutely more practical for a large number of finished products. 5, plastic bearings in operation without a little noise, has a certain vibration absorption function. 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. 6, plastic sliding bearing practical for high and low temperature operation-200 ~ + 250 degrees. 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. Plastic sliding bearing is not only a kind of sleeve but also a linear sliding bearing, but the material must be self-lubricated to improve its comprehensive wear resistance For example, the current market common CSB-LIN PLASTIC LINEAR bearings are materials through lubricants and Reinforced Fiber Modified by engineering plastics, its wear resistance is particularly outstanding. Problems with plastic bearings 1. Plastic bearings for the rest of the bearings, the ability to withstand high temperatures is poor. 2. Plastic bearing low speed, low load, poor mechanical performance. Plastic bearings will be divided into many types, the following number of common types of plastic bearings. 1. Refined plastic bearings: refined plastic bearings, plastic bearings than the traditional precision and tolerance has improved. It adopts the material system of inner and outer ring, rotating body and holding frame, which can be used in fine and high-speed operation on the basis of sticking to the tradition of plastic bearing. Usually the inner and outer rings are made of Pom, PPS, or peek, a rigid frame made of glass fiber reinforced Nylon 66(rpa66-25) , or peek, a rotating body made of glass, stainless steel or ceramic balls. 2. Corrosion resistant plastic bearings: There are a number of data solutions for different uses, working well even in the most brutal acid/alkali/salt/solvent/oil/gas/seawater erosion to protect the durability and life expectancy of the illusion. 3. ACID-AND ALKALI-RESISTANT PLASTIC BEARINGS: HDPE, PE, uhmwpe materials have been proved to be suitable for absolutely weak acid-base cross environment (30% cucl2 solution and 30% naoh solution test OK) , PVDF and ptfe materials can be used for strong acid-and Alkali Environment, among them, PTFE can be used in all concentrated acid and alkali occasions, including HF and fuming sulfuric acid and nitric acid (more than 98%) . Ceramic bearing because of its metal bearing incomparable excellent performance, high temperature resistance, super strength and so on in the new material world Clueless. In the past ten years, it has been widely used in various fields of national economy and people’s livelihood. 4. High temperature resistant plastic bearings: PVDF, PTFE (Teflon) , PPS (poly(p-phenylene sulfide)) , peek (polyether ether ketone) , Pi (polyether imide) have all proved to be a fantasy material for the manufacture of high temperature plastic bearings, in which Pi can be used at long-term temperatures of 290 °C, the maximum short-term temperature resistance may reach 350 °C. It’s one of the best engineered plastics known for its high-temperature properties. 5. Plastic housings and plastic spherical bearings: Plastic bearing with a unique weight, simple device, anti-corruption, can be free from maintenance, in addition to the common cast iron or stamping seat does not have the shock absorption function. With the development of new data, it is more and more widely used in engineering.
