Please refer to the chart for more detailed information (Graph EPB16-1).The Relation of Load, Speed and TemperatureCSB-EPB16 allows the Max static load of 50Mpa, The max compressive deformation rate under the max load is listed in Graph EPB16-2, The actual load capacity of bearing is slightly less than 50Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.0m/s) results into higher temperature (Tmax: 130℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB16-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor  Graph EPB16-4 shows that as the same as most of the slide bearing materials, the friction factor of CSB-EPB16 is increasing along with the rotation speed under a certain loading while as shown in Graph EPB16-5, it is decreased along with the increasing of loading when the operation speed is stable. From Graph EPB16-6, it is found that the most suitable shaft roughness is Ra0.1 to Ra0.2. Smoother shaft or rougher shaft may result into friction factor increasing.CSB-EPB16DryGreaseOilWaterFriction coef. μ0.06~0.200.090.040.04Wearing and shaft materialGraph EPB16-7 and Graph EPB16-8 shows the wearing is considerably affected by the shaft materials. Heat-treated steel shaft and carbon steel shaft is good for this bearing material. Graph EPB16-8 tells that CSB-EPB16 is suitable for hardened chrome steel and hardened steel shaft in oscillation operation and is suitable for carbon steel and hardened steel shaft in rotation operation.Chemical ResistanceCSB-EPB16 is good at chemical resistance against weak acidic medium and various kinds of lubricants.Water AbsorbabilityThe water absorb rate of CSB-EPB16 is 0.2% under the atmospheric pressure while it is 0.4% when the material is immerged into water. With its low water absorbability, the material is suitable for humid environment applications.UV ResistanceDisintegration could be possible for the material CSBEPB16 after long period of exposing under the UV ray and therefore the performance of the material will be reduced.Bearing InstallationCSB-EPB16 The Interfit ToleranceDiameter 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
