The currently used FAG bearings can usually be divided into tumbling FAG bearings and sliding FAG bearings. The working principle of tumbling FAG bearings and sliding bearings can be distinguished by the title; the conflict during rolling bearing operation is rollover conflict; and the sliding FAG bearing The slipping conflict occurs during the operation. The size of the tumbling conflict force depends on the precision of the production. The size of the conflicting force of the sliding FAG bearing depends mainly on the sliding surface of the bearing. The sliding FAG bearing usually has a self-smoothing function, sliding FAG. Bearings are classified into non-metallic sliding bearings and metal sliding FAG bearings according to the information. Non-metallic sliding bearings are mainly based on plastic bearings; plastic FAG bearings are usually made of engineering plastics with better functions, compared with professional manufacturers. Engineering plastics self-smoothing modification skills; through the fiber, special smoothing agent, glass beads, etc., the engineering plastics are self-smooth and reinforced to achieve certain functions; then the modified plastics are injection molded into self-smooth plastic bearings. The current global comparison of professional manufacturers are Germany's IGUS and China's CSB. Division. The most widely used metal sliding bearing is the three-layer composite FAG bearing; this FAG bearing is usually based on carbon steel plate; after sintering, a layer of spherical copper powder is sintered on the steel plate; then on the copper powder layer. Sintering a layer of 0.02mm PTFE smoothing agent, the first effect of the center layer of spherical copper powder is to strengthen the connection strength between the steel plate and PTFE; of course, it also plays a certain load and smooth effect during operation. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
At present, the global manufacturers of professional products include GGB in the United States, OILES in Japan, and CSB in China. It is not difficult to see from the above that the following differences exist between plastic FAG bearings and metal sliding bearings:
1. All the plastic bearings are smooth; the service life is long, and the smooth sliding layer of the metal sliding FAG bearing is only the outer surface of 0. 003mm PTFE; when this thin layer of conflict is completed, the end of life is declared.
2, the use of plastic bearings will not appear rusty appearance and corrosion resistance; metal bearings are easy to rust and can not be used in chemical fluids,
3, the quality of plastic bearings is lighter than metal; this is more suitable for modern lightweight depiction trends,
4. The cost of making plastic FAG bearings is lower than that of metal. The plastic bearings are made by injection molding and are suitable for mass production.
5, plastic FAG bearings do not have any noise during operation; have a certain vibration absorption function, because plastic bearings have many advantages over metal sliding bearings; the current production value of plastic bearings is expanding; the application of plastic FAG bearings is also constantly Extension; from the fitness equipment to office equipment and the automotive industry, etc. have selected plastic bearings; the current car on the road does not use plastic FAG bearings. Plastic FAG bearing market prospects are infinitely broad!
