PV Value of Bearings

The max PV value of the CSB-EPB5 series bearing is 1.5N/ 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 EPB5-1).

The Relation of Load, Speed and Temperature

CSB-EPB5 allows the Max static load of 150Mpa, The max compressive deformation rate under the max load is listed in Graph EPB5-2, The actual load capacity of bearing is slightly less than 150Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.5m/s) results into higher temperature (Tmax: 250?) which decreases the load capacity of the bearing. Please refer to the Graph EPB5-3 for such variation.

The Friction Factor,Wearing and shaft material

Friction Factor
CSB-EPB5 Bearing Friction factor is increased along with the increasing of the operation speed under certain loading (See Graph EPB5-4. The friction factor of CSBEP5 is decreased along with the loading increasing not over 20Mpa (see Graph EPB5-5). The friction factor will not change much along with the speed when the loading is over 20Mpa. The Graph EPB5-6 shows that the bearing could achieve its best performance when the counter shaft surface roughness is around Ra0.6 to Ra0.8.

Wearing and shaft material

Graph EPB5-7 and Graph EPB5-8 show the test results of the material CSB-EPB5 running against different shaft materials. It is suitable for stainless steel and hot rolled carbon steel shaft when the loading is less than 2Mpa and it will be more suitable for heat treated steel and carbon steel shaft when the loading is over 2Mpa. Graph EPB5-7 shows CSB-EPB5 is good for rotation operation. Specially, from the Graph EPB5-9, it is read that CSB-EPB5 is with better performance under high temperature around 150Comparing with under the ambient temperature of 23?.

Chemical Resistance

Chemical Resistance of CSB-EPB5 is very good. It can work well in the heavy acid of 65%.

Water Absorbability

The water absorb rate of CSB-EPB5 is less than 0.1% under the atmospheric pressure while it is 0.5% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the material is stabilized for the applications under humid environment.

UV Resistance

CSB-EPB5 can maintain its performance to be stable even exposed in the UV ray for long period.
