PV Value of Bearings

The max PV value of the CSB-EPB14A series bearing is 0.4N/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 EPB14A-1).

The Relation of Load, Speed and Temperature

CSB-EPB14A allows the Max static load of 10Mpa, The max compressive deformation rate under the max load is listed in Graph EPB14A-2, The actual load capacity of bearing is slightly less than 10Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 5.0m/s) results into higher temperature (Tmax:260?) which decreases the load capacity of the bearing. Please refer to the Graph EPB14A-3 for such variation.

The Friction Factor,Wearing and shaft material

Friction Factor
 A rapid decrease in friction can be observed as load increases for CSB-EPB14A bearings. A higher surface speed has less impact on the coefficient of friction of this bearing.(EPB14A-4 and EPB14A-5) CSB-EPB14A 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 EPB14A-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.

Wearing and shaft material

CSB-EPB14A is suitable for almost all kinds of shaft materials. Graph EPB14-7 shows that the wearing feature of CSB-EPB14A is excellent when the shaft material are stainless steel?hardened Aluminum or hardened chrome steel. Graph EPB14-7 shows that the material CSBEPB14 is most suitable for the rotation operation. Since start-up friction is extremely low, this makes CSB-EPB14A bearings the ideal choice for oscillating or start-stop applications

Chemical Resistance

CSB-EPB14A is good at chemical resistance against weak acidic medium and various kinds of lubricants.

Water Absorbability

The water absorb rate of CSB-EPB14A 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 Resistance

CSB-EPB14A can maintain its performance to be stable even exposed in the UV ray for long period.
