轴承PV值

EPT系列轴承最大运行PV值为0.4N/mm2 x m/s; 由此决定轴承所承受的载荷与速度成反比，详情查阅图表EPT-1。

轴承的载荷、速度、温度

EPT系列轴承可承受最大静载荷为35Mpa，在此载荷下轴承的最大压缩变形量参考图表EPT-2;轴承实际工作载荷略小于35Mpa，载荷还受到运行速度以及温度的影响，速度越快(Vmax:1.0m/s)会导致摩擦温度上升，而温度上升(Tmax:80℃)会导致轴承的承载能力逐渐减弱，载荷随轴承工作温度变化情况参考图表EPT-3。

轴承的摩擦系数

EPT轴承摩擦系数受运动速度以及轴承载荷变化影响相对较小(见图表EPT-4与EPT-5)，这也是EPT作为塑料轴承通用型号选择的因素;此轴承可以一直保持比较低的摩擦系数从而确保整个摩擦磨损性能的优越性。根据图表EPT-6显示EPT轴承的摩擦系数还会受到对磨轴表面粗糙度的影响而发生变化，我们推荐此轴承使用轴表面粗糙度值为Ra0.3~0.5um。

磨损与轴材料

轴材料对轴承的磨损有很大影响，但EPT轴承适合几乎所有的轴材料;通过图表EPT-7与图表EPT-8可以看出当使用硬铬钢轴或硬化钢轴以及硬化铝轴时EPT轴承的磨损特性都非常出色。

化学抗性

EPT塑料轴承能抵抗弱碱、弱酸以及各类润滑油的腐蚀。

吸水性

在标准大气压中，EPT塑料轴承的吸湿率为0.3%，浸泡水中最高吸水率为1.2%；较低的吸水率只有在极端应用中才需要更改轴承设计。

抗UV性能

EPT长久暴露在紫外线下颜色基本不会发生改变。材料的硬度，抗压强度和耐磨性能都不会改变。
