为了NSK轴承延长使用寿命，应注意工业维护，防止事故发生，保证运行的可靠性，提高生产率和经济性。应根据相应机械操作条件的操作标准定期进行维护。其内容包括监测运行状况，补充或更换润滑油，定期体检。作为一个运行中的维修项目，有旋转声音、振动、温度、润滑油状态等。
In order to prolong the service life of NSK bearings, attention should be paid to industrial maintenance to prevent accidents, ensure the reliability of operation and improve productivity and economy. Maintenance should be carried out regularly according to the operating standa*** of the corresponding mechanical operating conditi***. Its contents include monitoring operation status, supplementing or replacing lubricants, and regular physical examination. As a maintenance project in operation, there are rotating sound, vibration, temperature, lubricant status and so on.
1。清洗：轴承拆卸和修理时，应先记录外观，确认剩余润滑油量，清洗前应取样检查润滑油。***和煤油是常用的清洁剂。去除清洗、粗清洗和精清洗，分别在容器内，首先放在金属网底部，使NSK轴承不直接接触容器污垢。
1. Cleaning: When disassembling and repairing bearings, the appearance should be recorded first, the amount of remaining lubricant should be confirmed, and the lubricant should be sampled and checked before cleaning. Gasoline and kerosene are commonly used detergents. Remove cleaning, rough cleaning and fine cleaning, respectively, in the container, first placed at the bottom of the metal mesh, so that the NSK bearings do not directly contact the containers dirt.
2。维护判断：为了判断拆下的轴承是否可以使用，清洗后应检查轴承。检查滚道表面、滚动表面和配合面、保持架磨损、间隙增大、尺寸精度降低。然后用一只手将不可分离的小滚珠轴承支撑在内环的水平面上，转动外环以确认其光滑度。
2. Maintenance judgment: In order to judge whether the removed bearings can be used, the bearings should be checked after cleaning. Check raceway surface, rolling surface and mating surface, cage wear, gap increase, dimension accuracy decrease. Then the inseparable ***all ball bearing is supported on the horizontal surface of the inner ring with one hand, and the outer ring is rotated to confirm its ***oothness.
3。润滑目的：滚动轴承的润滑目的是减少内摩擦和摩擦损失，防止燃烧和粘着。
3. Lubrication purpose: The lubrication purpose of rolling bearings is to reduce internal friction and friction losses and prevent combustion and adhesion.
减少摩擦和磨损。环、滚动体和夹紧弹簧的接触部件可防止金属接触，减少摩擦和磨损。
Reduce friction and wear. Contact parts of rings, rolling bodies and clamping springs can prevent metal contact and reduce friction and wear.
延长疲劳寿命。旋转过程中，滚动接触面的到良好的润滑，可延长滚动疲劳寿命。反之，如果NSK轴承润滑油的粘度低且润滑膜的厚度不好，则润滑油的粘度将缩短。
Extend fatigue life. Rolling fatigue life can be prolonged by good lubrication of rolling contact surface during rotation. Conversely, if the viscosity of NSK bearing oil is low and the thickness of lubricating film is not good, the viscosity of lubricating oil will be shortened.
4。安装：正确安装会影响精度、寿命和性能。因此，设计和装配部门应充分研究安装。希望按操作标准安装。
4. Installation: Correct installation will affect accuracy, life and performance. Therefore, design and assembly departments should fully study the installation. Hope to install according to operation standard.
圆锥滚子轴承和其余分形分离，滚动体，滚道表面可以单独检查。对于大尺寸，应仔细检查辊、滚道表面、保持架和固定表面的外观，因为它们不能用手旋转。
Tapered roller bearings are separated from other fractals. Rollers and raceway surfaces can be inspected separately. For large sizes, the appearance of rollers, raceway surfaces, cages and fixed surfaces should be carefully examined, as they cannot be rotated by hand.
5。我希望在安装前打开包装。一般油脂润滑，不干净，直接注入油脂。润滑油不需要清洗，但bi须使用仪器或高速轴承，并用干净的油清洗以去除防锈物质。去除防锈剂，容易生锈，所以不可忽视。此外，用NSK轴承润滑脂密封的轴承可直接使用而无需清洗。，
5. I hope to open the package before installation. General grease lubrication, not clean, direct injection of grease. Lubricants need not be cleaned, but Bi must be cleaned with instruments or high-speed bearings and clean with clean oil to remove rust-proof substances. Removal of rust inhibitors, easy to rust, so can not be ignored. In addition, bearings sealed with NSK bearing grease can be used directly without cleaning. ,
6。安装方法因轴承结构、配合和状况而异。一般来说，由于大多数轴承轴向旋转，内环需要过盈配合。圆柱孔、多压机或多用途热装。对于锥形孔，它们直接安装在NSK轴承锥形轴上或带有套筒。
6. Installation methods vary according to bearing structure, fit and condition. Generally speaking, because most bearings rotate axially, the inner ring needs interference fit. Cylindrical hole, multi-press or multi-purpose hot charging. For tapered holes, they are directly mounted on the tapered shaft of NSK bearings or with sleeves.
