PRODUCT INFORMATION
PV VALUE
The max PV value of the CSB-EPB20F plastic bearings is 0.15N/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 EPB20-1).
Load, speed and temperature
CSB-EPB20F allows the Max static load of 70Mpa, The max compressive deformation rate under the max load is listed in Graph EPB20-2. The actual load capacity of bearing is slightly less than 70Mpa, The bearing load is variable against the speed and temperature. Fast speed (Vmax: 0.5m/s) results into higher temperature (Tmax: 90℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB20-3 for such variation.

Friction factor, wear and shaft material
Friction factor
Friction factor
Similar with most of the plastic bearings, the friction factor of CSB-EPB20F is increased along with the operation speed when the loading is stable (see Graph EPB20-4) and is decreased along with the loading increasing when the operation speed is stable (see Graph EPB20-5). From Graph EPB20-6, it shows the friction factor of CSB-EPB20F is variable against different shaft surface roughness. The recommended shaft surface roughness is Ra0.3~0.6.

Wearing and shaft material
Graph EPB20-7 and EPB20-8 shows that CSB-EPB20F is rather suitable for hardened steel shaft and hardened chrome steel shaft under lower loading and Graph EPB20-7 shows that CSB-EPB20F wearing feature is better for oscillation operation than of rotation operation.

Chemical resistance
CSB-EPB20F is good at chemical resistance against weak acidic medium and various kinds of lubricants.

Water absorption
The moisture absorption of CSB-EPB20F plastic plain bearings is 0.2% in standard atmosphere. The max. water absorption is 0.8% in water. These values are very low, CSB-EPB20F plastic palin bearings is very well suited for used in water.

UV resistance
Disintegration could be possible for the material CSB-EPB20F after long period of exposing under the UV ray and therefore the performance of the material will be reduced.
