PV Value of Bearings

The max PV value of the CSB-EPB1 series bearing is 0.6N/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 EPB1-1).

The Relation of Load, Speed and Temperature

CSB-EPB1 allows the Max static load of 70Mpa, The max compressive deformation rate under the max load is listed in Graph EPB1-2, The actual load capacity of bearing is slightly less than 70Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax:1.0m/s) results into higher temperature (Tmax: 110?) which decreases the load capacity of the bearing. Please refer to the Graph EPB1-3 for such variation.

The Friction Factor,Wearing and shaft material

Friction Factor

Graph EPB1-4 shows that as the same as most of the slide bearing materials, the friction factor of CSB-EPB1 is increasing along with the rotation speed under a certain loading while as shown in figure EPB1-5, it is decreased along with the increasing of loading when the operation speed is stable. From figure EPB1-6, it is found that the most suitable shaft roughness is Ra0.2 to Ra0.6.Smoother shaft or rougher shaft may result into friction factor increasing.

Wearing and shaft material

Graph EPB1-7 shows the wearing is considerably affected by the shaft materials. Heat-treated steel shaft and carbon steel shaft is good for this bearing material. CSB-EPB1 is suitable for hardened chrome steel and hardened steel shaft in oscillation operation and is suitable for hardened chrome steel and hardened steel shaft in rotation operation.

Chemical Resistance

CSB-EPB1 is good at chemical resistance against weak acidic medium and various kinds of lubricants.

Water Absorbability

The water absorb rate of CSB-EPB1 is 0.2% under the atmospheric pressure while it is 0.5% when the material is immerged into water. With its low water absorbability, the material is suitable for humid environment applications.

UV Resistance

Disintegration could be possible for the material CSBEPB1 after long period of exposing under the UV ray and therefore the performance of the material will be reduced.
