Please refer to the chart for more detailed information (Graph EPB20-1).The Relation of Load, Speed and TemperatureCSB-EPB20 allows the Max static load of 40Mpa, The max compressive deformation rate under the max load is listed in Graph EPB20-2, The actual load capacity of bearing is slightly less than 40Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 0.5m/s) results into higher temperature (Tmax: 90℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB20-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor
?Similar with most of the plastic bearings, the friction factor of CSB-EPB20 is increased along with the operation speed when the loading is stable (see Graph EPB20-4) and is decreased along with the loading increasing when the operation speed is stable (see Graph EPB20-5). From Graph EPB20-6, it shows the friction factor of CSB-EPB20 is variable against different shaft surface roughness. The recommended shaft surface roughness is Ra0.3~0.6.CSB-EPB20DryGreaseOilWaterFriction coef.?μ0.07~0.200.090.040.04Wearing and shaft materialGraph EPB20-7 shows that CSB-EPB20 is rather suitable for hardened steel shaft and hardened chrome steel shaft under lower loading andGraph EPB20-7 shows that CSBEPB20 wearing feature is better for oscillation operation than of rotation operation.Chemical ResistanceCSB-EPB20 is good at chemical resistance against weak acidic medium and various kinds of lubricants.Water AbsorbabilityThe water absorb rate of CSB-EPB20 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 CSBEPB20 after long period of exposing under the UV ray and therefore the performance of the material will be reduced.Bearing InstallationCSB-EPB20?The Interfit ToleranceDiameter mmTolerance after fit E10Fit Housing H7Fit Shaft?h9>0ï½3+0.014ï½+0.0540ï½+0.0100ï½-0.025>3ï½6+0.020ï½+0.0680ï½+0.0120ï½-0.030>6ï½10+0.025ï½+0.0830ï½+0.0150ï½-0.036>10ï½18+0.032ï½+0.1020ï½+0.0180ï½-0.043>18ï½30+0.040ï½+0.1240ï½+0.0210ï½-0.052>30ï½50+0.050ï½+0.1500ï½+0.0250ï½-0.062>50ï½80+0.060ï½+0.1800ï½+0.0300ï½-0.074>80ï½120+0.072ï½+0.2120ï½+0.0350ï½-0.087>120ï½180+0.085ï½+0.2450ï½+0.0400ï½-0.100
