EPB14 Plastic Plain Bearings
Econimic solution for high speed application. Under the temperature of 260?, the material can still have good chemical resistance feature. It is not suitable for high load application. When the temperature is higher than 135?, additional location ring is neccessary.
Continuous working temperature: -200?~260?;
Maintenance-free dry operation;
Low friction requirement;
High surface speed under low load;

PV Value of Bearings
The max PV value of the CSB-EPB14 series bearing is 0.3N/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 EPB14-1).
The Relation of Load, Speed and Temperature
CSB-EPB14 allows the Max static load of 8Mpa, The max compressive deformation rate under the max load is listed in Graph EPB14-2, The actual load capacity of bearing is slightly less than 8Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 2.0m/s) results into higher temperature (Tmax: 260?) which decreases the load capacity of the bearing. Please refer to the Graph EPB14-3 for such variation.
The Friction Factor,Wearing and shaft material
Friction Factor
The coefficient of friction decreases like the wear resistance with increasing surface speed. In contrast, a higher surface speed has less impact on the coefficient of friction of CSB-EPB14 bearing (Graph EPB14-4 and EPB14-5). From the figure EPB14-6, we could see that the friction factor is variable against the changing of shaft roughness. The recommended shaft roughness is Ra0.3~0.5.
CSB-EPB14 | Dry | Grease | Oil | Water |
Friction coef. µ | 0.03~0.15 | 0.09 | 0.04 | 0.04 |
Wearing and shaft material
The shaft material is an important media for the bearing wearing but CSB-EPB14 is suitable for almost all kinds of shaft materials. Graph EPB14-7 shows that the wearing feature of CSB-EPB14 is excellent when the shaft material are hardened chrome steel or hardened steel. Graph EPB14-7 shows that the material CSB-EPB14 is most suitable for the rotation operation.
Chemical Resistance
Chemical Resistance of CSB-EPB14 is very good. It can work well in the heavy acid of 65%.
Water Absorbability
The water absorb rate of CSB-EPB14 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-EPB14 can maintain its performance to be stable even exposed in the UV ray for long period.
