当从淮安NSK轴承座或轮毂上拆下外圈时，不当操作或损坏将导致外圈底座上有毛刺或凸起。如果使用轴承工具时意外地凿出轴承座，则凿槽附近的区域将增大。如果在重新安装轴承外圈之前这些凸块没有被压平或抛光，凸块会通过外圈影响外圈的内表面，导致相应的凸块。当滚动体冲击这些凸区域时，应力增大，导致轴承过早疲劳。
When the outer ring is removed from the Huai'an NSK bearing seat or hub, improper operation or damage will result in burrs or bulges on the outer ring base. If the bearing seat is accidentally chiseled out when using the bearing tool, the area near the chisel groove will increase. If these bumps are not flattened or polished before the bearing outer ring is reinstalled, the bumps will affect the inner surface of the outer ring through the outer ring, resulting in the corresponding bumps. When the rolling element impacts these convex regi***, the stress increases, leading to premature fatigue of the bearing.
1：由于轴承座磨损，轴承在运行中松动，造成磨损。结果，调心滚子轴承外圈出现金属撕裂和磨损。
1: Because of the wear of the bearing seat, the bearing loosened in operation, resulting in wear and tear. As a result, metal tearing and wear occurred in the outer ring of the self-aligning roller bearing.
2：匹配不当导致典型的摩擦腐蚀。轴承及其底座在载荷作用下的相对位移会引起磨损和腐蚀。
2: Improper matching results in typical friction corrosion. The relative displacement of bearing and its base under load will cause wear and corrosion.
3：由于分离轴承座上的尖头造成应力集中，外滚道部分脱落。
3: Because of the stress concentration caused by the cusp on the separation bearing seat, the outer raceway part falls off.
4：外圈上的痕迹是轴承座上的突出物造成的。淮安NSK轴承外环的内滚道对应于外环上的痕迹，在那里会发生剥落。
4: The mark on the outer ring is caused by the protrusion on the bearing seat. The inner raceway of Huaian NSK bearing outer ring corresponds to the marks on the outer ring, where peeling occurs.
轴承损坏的原因是什么？
What is the cause of bearing damage?
过大的预紧力会产生大量的热量，导致轴承损坏。损坏形式与润滑不足引起的损坏形式相似。
Excessive preload will generate a lot of heat, leading to bearing damage. The damage forms are similar to those caused by insufficient lubrication.
这两种激励措施常常被混淆，因此需要进行彻底的检查来确定问题的根源。适用于一般操作的润滑油可能不适用于具有高预紧力的轴承，因为油膜的强度可能不足以承受过高负荷。淮安NSK轴承高预载下润滑失效造成的损坏与润滑不足造成的损坏相同。
These two incentives are often confused, so a thorough examination is needed to determine the root cause of the problem. Lubricants suitable for general operation may not be suitable for bearings with high preload, as the strength of the oil film may not be sufficient to withstand excessive load. The damage caused by lubrication failure of Huaian NSK bearing under high preload is the same as that caused by insufficient lubrication.
1：由于过载，圆柱滚子轴承的滚子表面开裂。
1: Because of overload, the roller surface of cylindrical roller bearing cracks.
2：圆锥滚子轴承严重过载，导致滚子过早严重疲劳剥落。重载会导致滚筒上的金属板脱落。
2: Tapered roller bearings are seriously overloaded, leading to premature and severe fatigue spalling of the rollers. He***y load will cause the metal plate on the drum to fall off.
在高预紧力下，即使使用极压润滑剂承载重物，也可能发生另一种形式的损坏。尽管润滑剂可以应付负载并防止滚动部件或滚道上的划痕，但重载会导致表面过早的疲劳剥落。这种剥落的发生和淮安NSK轴承寿命将取决于轴承的预紧力和承载能力。
Under high preload, even if extreme pressure lubricants are used to carry he***y loads, another form of damage may occur. Although lubricants can cope with loads and prevent scratches on rolling parts or raceways, he***y loads can lead to premature fatigue spalling of surfaces. The occurrence of such peeling and the life of Huaian NSK bearings will depend on the preload and bearing capacity of the bearings.
3：圆锥滚子轴承内圈润滑膜厚，低速不足。
3: Tapered roller bearing inner ring lubrication film thick, low speed insufficient.
4：调心滚子轴承滚道脱落严重。
4: The aligning roller bearing raceway falls off seriously.
5：重载低速使圆锥滚子轴承滚道磨损严重。
5: He***y load and low speed make the tapered roller bearing raceway worn seriously.
