Full Job Description:

CSB Plastic is one of the leading China epb23 plastic plain bearings manufacturers and suppliers, and also a professional epb23 plastic plain bearings factory and company, we are always at your services.EPB23 Plastic Plain Bearings● High temperature and wear resistance material comforms to FDA regulation. It is suitable for the food machinery where the food is directly contacted with the material under the high temperature of 180℃.● Continuous working temperature: -100℃~180℃;● Good wear resistance under high load;● For food industry under high temperature;● No special requirement on the surface roughness;The Material Data SheetTypical ItemStandardUnitCSB-EPB23? ?DensityISO1183g/cm31.42? ?ColorBlue? ?Dynamic friction /steel(dry)0.10-0.20? ?Max.

Please refer to the chart for more detailed information (Graph EPB23-1).The Relation of Load, Speed and TemperatureCSB-EPB23 allows the Max static load of 60Mpa, The max compressive deformation rate under the max load is listed in Graph EPB23-2, The actual load capacity of bearing is slightly less than 60Mpa, The bearing load is variable against the speed and temperature, Fast speed(Vmax: 1.0m/s) results into higher temperature (Tmax: 180℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB23-3 for such variation.The Friction Factor,Wearing and shaft materialFriction Factor
?CSB-EPB23 Bearing Friction factor is not so sensitive to the operation speed (see Graph EPB23-4). The friction factor is considerably decreased along with the loading increasing and it will be turned to be stable when the loading reaches 20Mpa. Graph EPB23-5 shows the friction factor of the bearing is also not sensitive to the shaft roughness but we still recommend that the roughness of the shaft should be neither too smooth nor too rough. It is recommended to keep the roughness of the shaft to be within the range of Ra0.6 to Ra0.9.CSB-EPB23DryGreaseOilWaterFriction coef.?μ0.09~0.200.090.040.04Wearing and shaft materialGraph EPB23-7 shows that the CSB-EPB23 material is not sensitive with different materials under the rotating operation. It is suitable for hard shaft and high speed steel shaft as well as hard chrome steel shaft. Graph EPB23-8 shows that the hard chrome steel shaft is most suitable for using CSB-EPB23 bearing because the wearing speed is not sensitive when the loading is increased. From the Graph EPB23-8, it shows that CSB-EP23 features different performance.Chemical ResistanceCSB-EPB23 is good at chemical resistance against weak acidic medium and various kinds of lubricants.Water AbsorbabilityThe water absorb rate of CSB-EPB23 is 0.6% under the atmospheric pressure while it is 1.9% when the material is immerged into water. The application environment has to be considered because of its water absorb properties.UV ResistanceThe color of CSB-EPB23 could be dimmed when it is exposed into the UV ray. The material performance stays stable.Bearing InstallationCSB-EPB23?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
