Please refer to the chart for more detailed information (Graph EPB10-1).The Relation of Load, Speed and TemperatureCSB-EPB10 allows the Max static load of 160Mpa, The max compressive deformation rate under the max load is listed in Graph EPB10-2, The actual load capacity of bearing is slightly less than 160Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.5m/s) results into higher temperature (Tmax: 260℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB10-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor  Graph EPB10-4 shows that the friction factor of CSBEPB10 is increasing along with the operation speed when the loading is stable within 30 Mpa. When the loading is higher than 30Mpa, the friction factor variation will not be detectable. Graph EPB10-6 describes that CSB-EPB10 is featured best within the shaft surface roughness of Ra0.6~0.8.CSB-EPB10DryGreaseOilWaterFriction coef. μ0.10~0.250.090.040.04Wearing and shaft materialGraph EPB10-7 and Graph EPB10-8 is the comparing test for the CSB-EPB10 wearing against different shaft materials. Stainless steel and hot-rolled steel shaft is the best shaft material for CSB-EPB10 when the loading is lower than 2Mpa. Graph EPB10-7 shows that CSB-EPB10 is most suitable for rotation operation. Graph EPB10-9 shows a very special feature of CSB-EPB10 that the wearing Features of CSB-EPB10 is much better when the temperature is 150 ℃ than that of the temperature of 23℃.Chemical ResistanceChemical Resistance of CSB-EPB10 is very good. It can work well in the heavy acid of 65%.Water AbsorbabilityThe water absorb rate of CSB-EPB10 is less than 0.1% under the atmospheric pressure while it is 0.5% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the applications under humid environment.UV ResistanceCSB-EPB10 can maintain its performance to be stable even exposed in the UV ray for long period.
