Product Name:EPB9 Plastic Plain Bearings
Product Description:
CSB Plastic is one of the leading China epb9 plastic plain bearings manufacturers and suppliers, and also a professional epb9 plastic plain bearings factory and company, we are always at your services.EPB9 Plastic Plain Bearings● Self-lubricated material with good elctricity conductivity.Mainly used with the high load and electricity conductive evironment.● Continuous working temperature: -40℃～130℃;● Specially use for static electricity existing environment;● Suitable for low speed operation;● Higher load capacity.The Material Data SheetTypical ItemStandardUnitCSB-EPB9? ?DensityISO1183g/cm31.24? ?ColorBlack? ?Dynamic friction /steel(dry)0.10-0.40? ?Max.

Please refer to the chart for more detailed information (Graph EPB9-1).The Relation of Load, Speed and TemperatureCSB-EPB9 allows the Max static load of 105Mpa, The max compressive deformation rate under the max load is listed in Graph EPB9-2, The actual load capacity of bearing is slightly less than 105Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 0.8m/s) results into higher temperature (Tmax: 130℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB9-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor?Graph EPB9-4 shows that the friction factor of CSB-EPB9 is much higher than those of other materials because the electronic conductive fiber is embedded into the bearing material. It is induced that the friction performance will be better when the bearing is lubricated. Graph EPB9-5 shows that the friction factory is decreasing along with the loading increasing and Graph EPB9-6 shows that the friction factor is increasing along with the shaft roughness increasing when the shaft roughness is between Ra0.1 to Ra0.5. This effecting will be less when the shaft roughness is between Ra0.5 to Ra1.6.CSB-EPB9DryGreaseOilWaterFriction coef.?μ0.10~0.400.090.040.04Wearing and shaft materialGraph EPB9-7 shows the different results of the material against different shaft materials. It induces that the bearing material is good for hard chrome steel shaft under low loading operation condition and good for hardened carbon steel shaft under high loading rotation operation.Chemical ResistanceCSB-EPB9 is good at chemical resistance against weak acidic medium and various kinds of lubricants.Water AbsorbabilityThe water absorb rate of CSB-EPB9 is 1.5% under the atmospheric pressure while it is 7.6% when the material is immerged into water. The application environment has to be considered because of its water absorb properties.UV ResistanceWhen CSB-EPB9 is exposed into the UV ray, the material performance stays stable.Bearing InstallationDiameter mmTolerance after fit E10Fit Housing H7Fit Shaft h9>0～3+0.014～+0.0540～+0.0100～-0.025>3～6+0.020～+0.0680～+0.0120～-0.030>6～10+0.025～+0.0830～+0.0150～-0.036>10～18+0.032～+0.1020～+0.0180～-0.043>18～30+0.040～+0.1240～+0.0210～-0.052>30～50+0.050～+0.1500～+0.0250～-0.062>50～80+0.060～+0.1800～+0.0300～-0.074>80～120+0.072～+0.2120～+0.0350～-0.087>120～180+0.085～+0.2450～+0.0400～-0.100
