Please refer to the chart for more detailed information (Graph EPB2D-1). The Relation of Load, Speed and Temperature CSB-EPB2D allows the Max static load of 25Mpa, The max compressive deformation rate under the max load is listed in Graph EPB2D-2, The actual load capacity of bearing is slightly less than 25Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.2m/s) results into higher temperature (Tmax:80?) which decreases the load capacity of the bearing.Please refer to the Graph EPB2D-3 for such variation. The Friction Factor,Wearing and shaft material Friction Factor Graph EPB2D-4 shows that the friction factor of CSBEPB2D is initially increased along with the operation speed increasing when the loading is stable but when the speed reaches over 0.25m/s, it is decreased along with the operation speed increasing. Graph EPB2D-5 shows that the friction factor of CSB-EPB2D is decreasing along with the loading increasing when the operation speed is stable. Graph EPB2D-6 shows the friction factor of CSBEPB2D is sensitive to the shaft roughness. The best shaft roughness for this material is Ra0.3~0.6. CSB-EPB2D Dry Grease Oil Water Friction coef.?µ 0.05~0.25 0.09 0.04 0.04 Wearing and shaft material Graph EPB2D-7 and Graph EPB2D-8 shows that the hardened chrome steel shaft is good for CSB-EPB2D bearings under lower loading and stainless steel shaft is better when the loading is over 1.0Mpa. Graph EPB2D-8 shows hardened steel shaft is recommended in rotation operation but hardened chrome steel shaft is recommended in oscillation operation. Chemical Resistance CSB-EPB2D is good at chemical resistance against mild base, weak acidic medium and various kinds of lubricants. Water Absorbability The water absorb rate of CSB-EPB2D is 0.2% under the atmospheric pressure while it is 1.1% when the material is immerged into water. With its low water absorbability, the material is suitable for humid environment applications.? UV Resistance The color of CSB-EPB2D will become lighter when it is exposed into the UV ray. The hardness, Compressive strength and wear resistance of the material is also stable under such condition.
