PRODUCT INFORMATION
PV VALUE
The max PV value of the CSB-EPB5F plastic bearings 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 EPB5-1).
Load, speed and temperature
CSB-EPB5F allows the Max static load of 110Mpa, 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 110Mpa, 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.

Friction factor, wear and shaft material
Friction factor
CSB-EPB5F Bearing Friction factor is increased along with the increasing of the operation speed under certain loading (See Graph EPB5-4). The friction factor of CSB-EP5 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-EPB5F 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-EPB5F is good for rotation operation. Specially, from the Graph EPB5-9, it is read that CSB-EPB5F is with better performance under high temperature around 150℃ comparing with under the ambient temperature of 23℃.
