Zhenjiang NSK bearings can not be directly observed in operation, but can be detected by noise, vibration, temperature, lubricant and other conditions. Typical example of bearing damage;
铆钉松动或断裂，滚动体断裂。其原因是：扭矩负荷过大、润滑不足、转速变化频繁、振动大、轴承安装倾斜、异物堵塞。
The rivet loosens or breaks, and the rolling body breaks. The reasons are: excessive torque load, insufficient lubrication, frequent changes in rotational speed, large vibration, inclined bearing installation, foreign body blockage.
对策：了解使用条件和润滑条件是否适当，注意轴承的使用，研究保持架的选择是否适当，以及轴承箱的刚度是否为载荷要求。
Countermeasure: Know whether the use conditions and lubrication conditions are appropriate, pay attention to the use of bearings, study whether the selection of cages is appropriate, and whether the stiffness of the bearing box is a load requirement.
内部或外部滑动会导致镜子或变色，有时会被卡住。其主要原因是：协调不当、套筒拧紧不当、温升异常、主机负荷过大。
Sliding inside or outside can cause mirrors or discoloration and sometimes get stuck. The main reasons are: improper coordination, improper sleeve tightening, abnormal temperature rise and excessive load on the main engine.
对策：须重新检查镇江NSK轴承干涉的适用性，检查工作条件，检查车轴和轴承箱的精度。
Countermeasure: It is necessary to re-examine the applicability of interference of Zhenjiang NSK bearings, check working conditions and check the accuracy of axles and bearing boxes.
表面部分或完全生锈，滚动体生锈。其原因是：贮存、包装不当、防锈剂不足、水和酸性溶剂侵入、直接使用手轴承。
The surface is partially or completely rusted, and the rolling body is rusted. The reasons are: improper storage, improper packaging, inadequate rust inhibitors, water and acid solvent intrusion, direct use of hand bearings.
对策：防止油库生锈，定期不规则补油，加强密封性能，定期检查润滑油，及时更换不合格或劣化油，正确使用轴承。
Countermeasure: Prevent rust in oil depot, regularly and irregularly replenish oil, strengthen sealing performance, regularly check lubricating oil, timely replace unqualified or deteriorated oil, correct use of bearings.
损伤状态：当金属粉末或镇江NSK轴承异物被堵塞时，凹坑形成在滚道或旋转表面上。由于安装的同时冲击，在辊之间形成凹（粗糙硬度压痕）。
Damage status: When metal powder or foreign body of Zhenjiang NSK bearing is blocked, the pit is formed on the raceway or rotating surface. Due to the simultaneous impact of the installation, a concave (Rough hardness indentation) is formed between the rollers.
原因：异物如金属粉末咬伤。装配或运输过程中的冲击载荷太大。
Cause: foreign body such as metal powder bite. The impact load during assembly or transportation is too large.
测量：冲击套筒。改进的密封装置。过滤润滑油。改进组装和使用。
Measurement: impact sleeve. Improved sealing device. Filter lubricating oil. Improved assembly and use.
损伤状态：所谓磨损是由于摩擦引起的，如滚道表面或滚动表面、滚子端面、轴环表面和笼凹表面。
Damage status: The so-called wear is caused by friction, such as raceway surface or rolling surface, roller end surface, axle ring surface and cage concave surface.
原因：侵入异物、锈蚀和腐蚀。润滑。滚动体不规则运动引起的滑动。
Reason: invasion of foreign bodies, rust and corrosion. Lubrication. Slipping caused by irregular movement of rolling elements.
措施：改进密封装置。清洁镇江NSK轴承箱。充分过滤润滑油。检查润滑剂和润滑方法。防止非线性。
Measures: improve the sealing device. Clean Zhenjiang NSK bearing box. Fully filtrate lubricating oil. Check lubricants and lubrication methods. Prevent nonlinearity.
错误标记缩进6。轴承
Error mark indent 6. Bearing
损伤状态：在微振动过程中，由于滚动体与滚道轮接触部位的振动和振动，产生磨损，产生布氏压痕。
Damage state: In the process of micro-vibration, due to the vibration and vibration of the contact part between the rolling body and the raceway wheel, wear and tear occurs and Brinell indentation occurs.
原因：运输过程中轴承的振动和摆动。小振幅振荡运动。润滑。
Cause: vibration and swing of bearing during transportation. Small amplitude oscillatory motion. Lubrication.
措施：铰接轴和轴承箱在运输过程中固定。内环和外圈应在运输过程中分开包装。增加预紧力以减少振动。使用合适的润滑剂。
Measures: articulated shaft and bearing box are fixed during transportation. The inner ring and outer ring should be separately packed during transportation. Increase preload to reduce vibration. Use suitable lubricants.
只要我们避免这种情况，定期维护轴承就能保证轴承的正常使用寿命和性能。
As long as we avoid this situation, regular maintenance of bearings can ensure the normal service life and performance of bearings.
