PV Value of BearingsThe max PV value of the CSB-EPB4 series bearing is 1.4N/ mm2*m/s which determines the load capacity of bearing is inversely proportional to the speed. Please refer to the chart for more detailed information (Graph EPB4-1).





The Relation of Load, Speed and Temperature


CSB-EPB4 allows the Max static load of 90Mpa, The max compressive deformation rate under the max load is listed in Graph EPB4-2, The actual load capacity of bearing is slightly less than 90Mpa, 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 EPB4-3 for such variation.





The Friction Factor,Wearing and shaft material


Friction Factor
?Friction factor will be slightly decreased along with the speed increasing under certain loading of the rotation operation (see Graph EPB4-4) and it will be slightly decreased along with the loading increasing under certain speed of the rotation operation especially when the loading is less than 30Mpa. Graph EPB4-5 tells that the friction of the CSB-EPB4 is not changed at all when the shaft roughness is between Ra0.1 to Ra0.4 and will be considerably increased when the shaft roughness is over Ra0.4. So the recommended shaft roughness is Ra0.1- Ra0.4.

Wearing and shaft material


Graph EPB4-7 shows that CSB-EPB4 is suitable for most of the shaft materials under low loading rotation operation and it is good for hardened carbon steel shaft under high loading rotation operation (see Graph EPB4-7). From Graph EPB4-8, we can also read that CSB-EPB4 is suitable for stainless steel shaft under oscillation operation and good for hot rolled carbon steel and hardened carbon steel shaft under rotation operation.





Chemical Resistance


The Chemical Resistance of CSB-EPB4 is fairly good against most of Acid and Alkalis.


Water Absorbability


The water absorb rate of CSB-EPB4 is 0.1% under the atmospheric pressure while it is 0.3% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the applications under humid environment.





UV Resistance


Disintegration could be possible for the material CSBEPB4 after long period of exposing under the UV ray and therefore the compressive strength will be reduced.
