镇江NSK轴承是一种元件，广泛应用于各个领域，根据结构或类型分为多种，并根据摩擦特性来分类常见的滚动轴承和滑动轴承，两者都有所不同。滚动轴承的摩擦阻力远小于滑动轴承的摩擦阻力。它具有启动快、效率高的优点。与滑动轴承相比，滚动轴承是大的优点。但是也有缺点，即尺寸较大，所以吸收振动的能力较弱，在高速运行时间较短，长期使用也会发出较大的异常声音。滚动轴承和滑动轴承的另一个本质区别是滚动轴承是表面接触，而滑动镇江NSK轴承是点接触。滚动轴承接触面大，结构简单，操作拆卸方便，对滑动轴承的润滑要求高。
Zhenjiang NSK bearing is a kind of component, which is widely used in various fields. It is divided into many kinds according to its structure or type, and classifies common rolling bearings and sliding bearings according to their friction characteristics. Both of them are different. The friction resistance of rolling bearings is much smaller than that of sliding bearings. It has the advantages of fast start up and high efficiency. Compared with plain bearings, rolling bearing is a great advantage. But there are also drawbacks, that is, the larger size, so the ability to absorb vibration is weak, in high-speed running time is short, long-term use will also emit a larger abnormal sound. Another essential difference between rolling bearings and sliding bearings is that the rolling bearings are surface contact, while the sliding Zhenjiang NSK bearings are point contact. Rolling bearing has large contact surface, simple structure, convenient operation and disassembly, and high lubrication requirement for sliding bearings.
当双向推力球轴承在拆卸检查后损坏时，可根据轴承的损坏程度来判断故障和轴承损坏。
When the two-way thrust ball bearing is damaged after disassembly inspection, the fault and bearing damage can be judged according to the damage degree of the bearing.
在周期性波动载荷下，内外滚道表面发生周期性接触应力变化。当应力循环次数达到一定值时，疲劳剥落发生在轧制面或内外滚道上。如果轴承载荷过大，则会加剧疲劳。此外，如果镇江NSK轴承错位，轴弯曲，滚道就会脱落。轴承滚道的疲劳剥落会降低轴的工作精度，引起振动和噪声机理。
Under cyclic loading, periodic contact stress changes on the inner and outer raceway surfaces. When the number of stress cycles reaches a certain value, fatigue peeling occurs on the rolling surface or inside and outside raceway. If the bearing load is too large, it will aggravate fatigue. Besides, if the NSK bearing of Zhenjiang is misplaced and the shaft is bent, the raceway will fall off. The fatigue peeling of the bearing raceway will reduce the working accuracy of the shaft and cause the vibration and noise mechanism.
燃烧轴承在滚道和滚动体上有回火颜色。温高通常是由于润滑不足，润滑不顺或恶化，以及过度轴承装配。
The combustion bearings have tempering colors on raceway and rolling body. High temperature is usually due to inadequate lubrication, poor lubrication or deterioration, and excessive bearing assembly.
镇江NSK轴承滚道与接触面的滚动面之间出现凹痕，表明轴承存在塑性变形。其原因是，这通常发生在低速轴承在静态或冲击载荷下，其中工作表面上的局部应力超过材料的屈服极限。
The dent between the NSK bearing raceway of Zhenjiang and the rolling surface of the contact surface indicates that the bearing has plastic deformation. The reason is that this usually occurs in low-speed bearings under static or impact loads, where the local stress on the working surface exceeds the yield limit of the material.
轴承套圈开裂是造成轴承配合过大、内外圈松动、轴承座变形、轴承表面安装和加工异常的主要原因。
Bearing ring cracking is the main reason for excessive bearing fit, loosening of inner and outer rings, bearing seat deformation, bearing surface installation and machining abnormalities.
其原因是润滑不足，滚动体断裂，阀座环歪斜等。
The reason is that the lubrication is insufficient, the rolling body is broken, the seat ring is skewed, etc.
可能的原因是滚子卡在笼子里或不够润滑。
The possible reason is that rollers are stuck in cages or not lubricated enough.
可能是落在阀座上的异物、镇江NSK轴承润滑油不足或润滑油水平不当。
It may be a foreign object falling on the valve seat, insufficient lubricating oil in Zhenjiang NSK bearing or improper lubricating oil level.
载荷、润滑、装配、环境条件、材料质量或制造精度是影响双向推力球轴承损坏的主要因素。
Load, lubrication, assembly, environmental conditions, material quality or manufacturing accuracy are the main factors affecting the damage of bi-directional thrust ball bearings.
