Normal tracks
Under rotary motion and load the rolling elements leave tracks on the raceways which are bright in appearance when the lubricant film separates well. The individual pattern of the tracks is, however, largely dependent on the illumination of the surface but it should be possible to recognise almost all the machining structure, particularly when working with a magnifying glass and microscope (compare with non-contact areas at the edge of the raceway!). Individual indentations of small foreign particles are inevita-ble. When lubrication is particularly good they are the only indication of the position of the load zones in the bearing.
When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature. It originates from chemical reactions of the steel with the lubricant or its additives and has no negative effect on the service life of the bearing. Quite the contrary: These surface features frequently indicate effective wear protection of an additive.
Usually brown or blue colours result. However, no obvious conclusions can be drawn from the colour about the operating temperature which led to its origin. Very different shades of colour have at times been observed on the rolling elements of a bearing al-though the operating conditions are very similar.
This oil discolouration should on no account be confused with the tempering colours which are found on faulty bearings in rare cases and which arise as a result of much higher temperatures.
Tracks in the form of equatorial lines are sometimes found on balls as well. They appear on angular contact ball bearings when the balls always have the same rotary axis. Any significant reduction in life does not derive from them.

正常轨迹
在转动和负载作用下，当润滑膜隔离良好时，滚动元件在滚道上留下的轨迹表面光亮。不过轨迹的独特模式在很大程度上取决于表面照明度，但几乎能识别所有的机械结构，尤其是在放大镜和显微镜的帮助下（与滚道边缘的非接触区相比）。小杂质的单个凹痕是难免的。当润滑非常好时，它们只出现在轴承负荷区部位。
当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。这源于钢与润滑剂或其添加剂的化学反应，对轴承的使用寿命没有负面影响。恰恰相反，这些表面特征通常反而起到额外的有效防止磨损的作用。
它们一般呈褐色或蓝色。但是，并不能由其呈现的颜色得出有关工作温度的确切结论。即便工作环境非常相似，有时也会从滚动元件上观察到差异悬殊的色调。
润滑油褪色绝不能与极少数情况下有缺陷轴承的回火温度相混淆，那是由高得多的温度所致。
在滚珠上有时也能发现赤道线式的轨迹。当球的旋转轴相同时，它们就会在角接触球轴承上出现。它们不会使轴承的使用寿命明显缩短。
