Please refer to the chart for more detailed information (Graph EPB24-1).The Relation of Load, Speed and TemperatureCSB-EPB24 allows the Max static load of 65Mpa, The max compressive deformation rate under the max load is listed in Graph EPB24-1, The actual load capacity of bearing is slightly less than 65Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.0m/s) results into higher temperature (Tmax: 200℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB24-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor?
?Graph EPB24-4 shows the friction factor of CSB-EPB24 is not obviously effected by the operation speed when the loading is stable and Graph EPB24-5 shows it will be decreasing along with the loading is increased from 0 to 20 Mpa when the operation speed is unchanged, furthermore the friction factor will not be changed when the loading reaches 20Mpa upward. The friction factor of CSB-EPB24 is increased along with the increasing of the shaft roughness. The recommended shaft roughness is Ra0.1 to Ra0.6.CSB-EPB24DryGreaseOilWaterFriction coef.?μ0.10~0.300.090.040.04Wearing and shaft materialGraph EPB24-7 and Graph EPB24-8 tells that the CSBEPB24 is very good for Hardened shaft and soft shaft and it features excellent both on hardened steel shaft and hardened shaft but the hardened chrome steel shaft is not good for CSB-EPB24 bearings. Graph EPB24-8 shows that the wearing of CSB-EPB24 is better on oscillation operation than on rotation operation. The wearing will be increased when the loading is over 10Mpa.Chemical ResistanceThe Chemical Resistance of CSB-EPB24 is fairly good against most of Acid and Alkalis.Water AbsorbabilityThe water absorb rate of CSB-EPB24 is less than 0.1% under the atmospheric pressure while it is less than 0.1% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the applications under humid environment or even in the water.UV ResistanceDisintegration could be possible for the material CSBEPB24 after long period of exposing under the UV ray and therefore the compressive strength will be reduced.Bearing InstallationCSB-EPB24?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
