        product introduces the characteristics and use of the HS331 non oil lubricated bearings, with woven copper net as substrate, using a special process, and the surface of the polymer (PTFE+Pb) firmly jogged. It takes full advantage of the metal box of multi-element polymer, has a low friction coefficient, good wear resistance and self lubrication properties, texture soft, easy installation, no maintenance, can make steel and copper on the insulation film mill, realize the ideal objective of gapless, undamped vibration, no noise, no oil lubrication. Widely used in car door hinge, joystick, need to self lubrication field office machinery, joint bearings with light load. The performance indexes of physical and mechanical properties of the relevant performance indicators related data maximum bearing static load N/mm2 100 matched shaft hardness of HRC 50~60 dynamic load N/mm2 80 roughness 0.32~0.63 max speed m/s 1 application temperature -200~+260 the highest PV value N/mm2.m/s 1.65 friction coefficient of u 0.05~0.2 product attributes friction characteristics in general, HS331 bearing without lubrication, friction coefficient is not fixed. The larger the load is, the smaller the relative friction coefficient; line speed is low, the friction coefficient is smaller; the bearing temperature, friction coefficient decreases. Typically, bearing in the wear process of friction coefficient will increase slightly. Load properties allow static load as static load, bearing the permanent deformation occurs in bearing design, which should be taken into account. Conventional deformation depends on the pressure, temperature and time. Dynamic load and dynamic load (vibration and swing), reducing the allowable load capacity. When the design, must choose the higher value of P. Dynamic allow allow dynamic load bearing load, depending on the sliding velocity. When the design, should also consider heat status of bearings, such as good heat radiation cooling condition, the increase of the PV value can range. The main factors that affect the life of other PV values are valid indicators to determine HS331 oil-free lubrication bearing life. If the requirements of life extension, the load must be reduced; load characteristics because of the static load, bearing the permanent deformation occurs in bearing design, which should be taken into account; the dynamic load (vibration and swing), reduces the service life of the bearing. Ambient temperature is higher, the HS331 non oil lubricated bearings service life is shorter. The roughness of the counterface surface roughness has great influence on bearing life, slowly oscillating, recommended Ra
