The max PV value of the EPX series bearing is 1.5N/mm2*m/s which detemines the load capacity of bearing is inversely proportional to the speed. Please refer to the chare for more detailed information (Graph EPX-1).

EPX allows the max static load of 150Mpa, The max compressive deformation rate under the max load is listed in Graph EPX-2; The actual load capaxity of bearing is slightly less than 150Mpa, The bearing load is variable against the speed and temperature, Fast speed(Vmax: 1.5m/s)results into higher temperture(Tmax: 250) which decreases the load capacity of the bearing. Please refer to the Graph EPX-3 for such variation.

EPX Bearing Friction factor is increased a along with the increasing of the operation speed under certain loading(See Graph EPX-4). The friction factor of EPX is decreased along with the loading increasing not over 20Mpa(See Graph EPX-5). The friction factor will not change much along with the speed when the loading is over 20Mpa. The Graph EPX-6 shows that the bearing could achieve its best performance when the counter shaft surface roughness is around Ra0.6 to Ra0.8.

Graph EPX-7 and Graph EPX-8 shows the test results of the material EPX running against different shaft material. It is suitable for stainless steel and hot rolled carbon steel shaft when the loading is less than 2Mpa and it will be more suitable for heat treated steel and carbon steel shaft when the loading is over 2Mpa. Graph EPX-7 shows EPX is good for rotation operation. Specially, from the Graph EPX-9, it is read that EPX is with better performance under high temperature around 150 comparing with under the ambient temperature of 23.

The Chemical Resistance of EPX is very good. It can work well in the heavy acid of 65%.

The water absorb rate of EPX is 0.1% under the atmospheric pressure while it is 0.5% when the material is immerged into water. The material performance and dimensions of the material is stabilized for the applications under humid environment.

EPX can maintain its performance to be stable even exposed in the UV ray for long period.
