1、偏心INA轴承保养（eccentric INA bearing maintenance）：
为了尽可能长时间地以良好状态维持INA轴承本来的性能，须保养、检修、以求防事故于未然，确保运转的可靠性，提高生产性、经济性。
In order to maintain the original performance of INA bearings in good condition for as long as possible, it is necessary to maintain, overhaul, prevent accidents in the future, ensure the reliability of operation, improve productivity and economy.
保养好相应机械运转条件的作业标准，定期进行。内容包括监视运转状态、补充或更换润滑剂、定期拆卸的检查。
Maintain the best operating standards for the corresponding mechanical operation conditions and carry out them regularly. The contents include monitoring operation status, replenishment or replacement of lubricants, and regular disassembly inspection.
作为运转中的检修事项，有偏心INA轴承的旋转音、振动、温度、润滑剂的状态等等。
As a maintenance in operation, there are eccentric INA bearing rotating sound, vibration, temperature, lubricant status and so on.
2、偏心INA轴承的检修（Maintenance of eccentric INA bearings）：
INA轴承的清洗：拆卸下偏心INA轴承检修时，首先记录偏心INA轴承的外观，确认润滑剂的残存量，取样检查用的润滑剂之后，洗偏心INA轴承。作为清洗剂，普通使用汽油、煤油。
Cleaning of INA bearings: When removing the eccentric INA bearings for overhaul, first record the appearance of the eccentric INA bearings, confirm the residual amount of lubricant, sample and inspect the lubricant, then wash the eccentric INA bearings. As a cleaning agent, gasoline and kerosene are commonly used.
拆下来的偏心INA轴承的清洗，分粗清洗和细清洗，分别放在容器中，先放上金属的网垫底，使INA轴承不直接接触容器的脏物。粗清洗时，如果使INA轴承带着脏物旋转，会损伤INA轴承的滚动面，应该加以注意。在粗清洗油中，使用刷子清除去润滑脂、粘着物，大致干净后，转入精洗。
The removal of the eccentric INA bearing cleaning, coarse cleaning and fine cleaning, respectively, placed in the container, first put metal mesh pad bottom, so that INA bearings do not directly contact the container dirt. In rough cleaning, if the INA bearing is rotated with dirt, the rolling surface of the INA bearing will be damaged, it should be noted. In crude oil wash, remove grease and adhesive with brush. After cleaning, turn to fine wash.
精洗，是将偏心INA轴承在清洗油中一边旋转，一边仔细的清洗。另外，清洗油也要经常保持清洁。
Fine washing is to rotate eccentric INA bearings in the cleaning oil while cleaning them carefully. In addition, cleaning oil should also be kept clean.
3、偏心INA轴承的检修和判断（Overhaul and judgement of eccentric INA bearings）：
为了判断拆卸下来的INA轴承是否可以使用，要在INA轴承洗干净后检查。检查滚道面、滚动面、配合面的状态、保持架的磨损情况、INA轴承游隙的增加及有无关尺寸精度下降的损伤，异常。非分离型小型球INA轴承，则用一只手将内圈支持水平，旋转外圈确认是否流畅。
In order to determine whether the dismantled INA bearing can be used, check after the INA bearing is cleaned. Check the state of raceway surface, rolling surface, mating surface, cage wear, INA bearing clearance increase and irrelevant dimension accuracy decline damage, abnormal. Non-detached small ball INA bearings, then with one hand to support the inner ring level, rotating the outer ring to confirm whether smooth.
圆锥滚子轴承等分离形INA轴承，可以对滚动体、外圈的滚道面分别检查。
Tapered roller bearings are equally divided INA bearings, which can check raceway surfaces of rolling bodies and outer rings separately.
大型INA轴承因不能用手旋转，注意检查滚动体、滚道面、保持架、挡边面等外观，INA轴承的重要性愈高愈须慎重检查。
Because large INA bearings can not be rotated by hand, pay attention to inspecting the appearance of rolling element, raceway surface, cage, side face and so on, the higher the importance of INA bearings, the more carefully inspected.
