PV Value of Bearings

The max PV value of the CSB-EPB15 series bearing is 0.9N/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 EPB15-1).

The Relation of Load, Speed and Temperature

CSB-EPB15 allows the Max static load of 70Mpa, The max compressive deformation rate under the max load is listed in Graph EPB15-2, The actual load capacity of bearing is slightly less than 70Mpa, The bearing load is variable against the speed and temperature, Fast speed (Vmax: 1.5m/s) results into higher temperature (Tmax: 100?) which decreases the load capacity of the bearing. Please refer to the Graph EPB15-3 for such variation.

The Friction Factor,Wearing and shaft material

Friction Factor
 Graph EPB15-4 shows that the friction factor of CSBEPB15 is not sensitive to the operation speed and Graph EPB15-5 shows that the friction factor is CSB-EPB15 is decreased along with the loading increasing and become stable when the loading is over 20Mpa. Graph EPB15-6 tells that the friction factor of CSB-EPB15 is also not sensitive to the shaft roughness but we still recommend the shaft roughness to be Ra0.3~0.6.

Wearing and shaft material

Graph EPB15-7 shows that the wearing of CSB-EPB15 is sensitive to different materials under rotation operation with the loading of 2Mpa. It is suitable for hardened shaft, high speed steel shaft and hardened chrome steel shaft in the rotation operation. Hardened chrome steel shaft is the best choice for CSB-EPB15(Graph EPB15-8). The wearing will be decreased as long as the loading increasing.

Chemical Resistance

CSB-EPB15 is good at chemical resistance against weak acidic medium and various kinds of lubricants.

Water Absorbability

The water absorb rate of CSB-EPB15 is 1.3% under the atmospheric pressure while it is 6.5% when the material is immerged into water. The application environment has to be considered because of its water absorb properties.

UV Resistance

CSB-EPB15 can maintain its color unchanged when it is exposed into the UV ray. The material performance stays stable.
