PV Value of Bearings
The max PV value of the CSB-EPB3 series bearing is 0.5N/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 EPB3-1).
The Relation of Load, Speed and Temperature
CSB-EPB3 allows the Max static load of 80Mpa, The max compressive deformation rate under the max load is listed in Graph EPB3-2, The actual load capacity of bearing is slightly less than 80Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.0m/s) results into higher temperature (Tmax: 130℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB3-3 for such variation.
The Friction Factor,Wearing and shaft material
Friction Factor
The friction factor of the sliding bearings is relative to the bearing load, operation speed and the roughness of the shaft material.CSB-EPB3 Bearing Friction factor decreased along with the increasing of the loading (See Graph EPB3-5) and increased along with the increasing of the operation speed(See Graph EPB3-4). The above feature induces the CSB-EPB3 material is applicable for the high load and low speed operation while too smooth and too rough surface may result into the increasing of friction factor. The recommended surface roughness of CSB-EPB3 is Ra0.5~Ra0.8 (See Graph EPB3-6).

Wearing and shaft material
Test of the bearing against various shaft materials shows that the material CSB-EPB3 features the best performance where the shaft material is carbon steel and hard chrome steel under low loading. (See Graph EPB3-7 and Graph EPB3-8). Therefore, the higher the load is, the more critical the hardness of the shaft will have to be. The softer shaft will be worn off sooner and as a result, the bearing wearing will be increased. But when the loading is increased over 2Mpa, the wearing of the bearing will be better along with the increasing of the shaft hardness. Refer to Graph EPB3-8. It shows that the material CSBEPB3 is better under the oscillation operation comparing with the rotation operation. Under the same condition, the wearing feature of the oscillation operation is much better than that of the rotation operation. This feature is sharply improved under higher loading.
Chemical Resistance
CSB-EPB3 is good at chemical resistance against weak acidic medium and various kinds of lubricants.
Water Absorbability
The water absorb rate of CSB-EPB3 is 0.7% under the atmospheric pressure while it is 4.0% when the material is immerged into water. The application environment has to be considered because of its water absorb properties.
UV Resistance
CSB-EPB3 can maintain its color unchanged when it is exposed into the UV ray. The material performance stays stable.

PV Value of BearingsThe max PV value of the CSB-EPB4 series bearing 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 EPB4-1).
The Relation of Load, Speed and Temperature
CSB-EPB4 allows the Max static load of 90Mpa, The max compressive deformation rate under the max load is listed in Graph EPB4-2, The actual load capacity of bearing is slightly less than 90Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.0m/s) results into higher temperature (Tmax: 200℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB4-3 for such variation.
The Friction Factor,Wearing and shaft material
Friction Factor
?Friction factor will be slightly decreased along with the speed increasing under certain loading of the rotation operation (see Graph EPB4-4) and it will be slightly decreased along with the loading increasing under certain speed of the rotation operation especially when the loading is less than 30Mpa. Graph EPB4-5 tells that the friction of the CSB-EPB4 is not changed at all when the shaft roughness is between Ra0.1 to Ra0.4 and will be considerably increased when the shaft roughness is over Ra0.4. So the recommended shaft roughness is Ra0.1- Ra0.4.

Wearing and shaft material
Graph EPB4-7 shows that CSB-EPB4 is suitable for most of the shaft materials under low loading rotation operation and it is good for hardened carbon steel shaft under high loading rotation operation (see Graph EPB4-7). From Graph EPB4-8, we can also read that CSB-EPB4 is suitable for stainless steel shaft under oscillation operation and good for hot rolled carbon steel and hardened carbon steel shaft under rotation operation.
Chemical Resistance
The Chemical Resistance of CSB-EPB4 is fairly good against most of Acid and Alkalis.
Water Absorbability
The water absorb rate of CSB-EPB4 is 0.1% under the atmospheric pressure while it is 0.3% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the applications under humid environment.
UV Resistance
Disintegration could be possible for the material CSBEPB4 after long period of exposing under the UV ray and therefore the compressive strength will be reduced.

PV Value of Bearings
The max PV value of the CSB-EPB 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 EPB-1).
The Relation of Load, Speed and Temperature
CSB-EPB allows the Max static load of 35Mpa, The max compressive deformation rate under the max load is listed in Graph EPB-2, The actual load capacity of bearing is slightly less than 35Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax:1.0m/s) results into higher temperature (Tmax: 80℃) which decreases the load capacity of the bearing. Please refer to the Graph EPB-3 for such variation.
The Relation of Friction Factor, Wearing and shaft material
Friction Factor
CSB-EPB friction factor is not sensitive to the operation speed and bearing loading (see Graph EPB-4 and GraphEPB-5). The above features are the most common considerations for the bearing material selection. The friction of CSB-EPB could be maintained at a relatively lower level so that the good wearing features are guaranteed. From the Graph EPB-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
The shaft material is an important media for the bearing wearing but CSB-EPB is suitable for almost all kinds of shaft materials. Graph EPB-7 and Graph EPB-8 show that the wearing feature of CSB-EPB is excellent when the shaft material are hardened chrome steel or hardened steel or hardened Aluminum.
Chemical Resistance
CSB-EPB is good at chemical resistance against mild base, weak acidic medium and various kinds of lubricants.
Water Absorbability
The water absorb rate of CSB-EPB is 0.2% under the atmospheric pressure while it is 1.2% when the material is immerged into water. With its low water absorbability, the material is suitable for humid environment applications.
UV Resistance
CSB-EPB can maintain its color unchanged when it is exposed into the UV ray. The hardness, Compressive strength and wear resistance of the material is also stable under such condition.
