Product Name:EPB17 Plastic Plain Bearings
Product Description:
CSB Plastic is one of the leading China epb17 plastic plain bearings manufacturers and suppliers, and also a professional epb17 plastic plain bearings factory and company, we are always at your services.EPB17 Plastic Plain Bearings● High speed and high temperature special material . It is suitable for middle load and high speed applications. It has good chemical resistance feature. When the temperature is higher than 135℃, additional location ring is neccessary.● Continuous working temperature: -200℃～260℃;● Middle load and high surface speed;● Suitable for hard material shaft;● High chemical resistance;● High load seal requirement;The Material Data SheetTypical ItemStandardUnitCSB-EPB17? ?DensityISO1183g/cm33.9? ?ColorDark Green? ?Dynamic friction /steel(dry)0.15-0.30? ?Max.

Please refer to the chart for more detailed information (Graph EPB17-1).The Relation of Load, Speed and TemperatureCSB-EPB17 allows the Max static load of 20Mpa, The max compressive deformation rate under the max load is listed in Graph EPB17-2, The actual load capacity of bearing is slightly less than 20Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 3.0m/s) results into higher temperature (Tmax:260℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB17-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor?
?A rapid decrease in friction can be observed as load increases for CSB-EPB17 bearings. A higher surface speed has less impact on the coefficient of friction of this bearing.(EPB17-4 and EPB17-5) CSB-EPB17 is suitable for applications in which high pv values are given mainly through the high surface speed and not as much through the surface pressure. From the figure EPB17-6, we could see that the friction factor is variable against the changing of shaft roughness. The recommended shaft roughness is Ra0.3~0.5.CSB-EPB17DryGreaseOilWaterFriction coef.?μ0.15~0.300.090.040.04Wearing and shaft materialCSB-EPB17 is suitable for almost all kinds of shaft materials. Graph EPB17-7 shows that the wearing feature of CSB-EPB17 is excellent when the shaft material are stainless steel、hardened Aluminum or hardened chrome steel. Graph EPB17-7 shows that the material CSBEPB17 is most suitable for the rotation operation. Since start-up friction is extremely low, this makes CSB-EPB17 bearings the ideal choice for oscillating or start-stop applicationsChemical ResistanceCSB-EPB17 is good at chemical resistance against weak acidic medium and various kinds of lubricants.Water AbsorbabilityThe water absorb rate of CSB-EPB17 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 ResistanceCSB-EPB17 can maintain its performance to be stable even exposed in the UV ray for long period.Bearing InstallationCSB-EPB17?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
