黑色氧化是INA轴承钢表面化学反应的一种表面处理方法。当零件在大约150摄氏度的工作温度下浸入碱性盐水溶液中时，会形成黑色氧化层。
Black oxidation is a surface treatment method of chemical reaction on the surface of INA bearing steel. Black oxide layer is formed when parts are immersed in alkaline brine solution at working temperature of about 150 degrees Celsius.
黑色氧化物的好处bi须通过单独的应用来判断，但这种处理没有任何危害。它已成功地应用于其余行业难以操作的INA轴承，如造纸机辊、机床和工业通风机。黑色氧化过程涉及许多参数。整个过程包括大约15个不同的浸渍步骤。在许多步骤中，化学成分、浓度、温度、浸渍时间和流体特性都可以调整。
The benefits of black oxide Bi must be judged by its application alone, but there is no harm in this treatment. It has been successfully applied to INA bearings which are difficult to operate in other industries, such as paper mill rolls, machine tools and industrial ventilators. Black oxidation process involves many parameters. The whole process includes about 15 different impregnation steps. In many steps, chemical composition, concentration, temperature, impregnation time and fluid characteristics can be adjusted.
为了达到***佳性能，建议内外环和辊均采用黑色氧化处理。黑色氧化可应用于大型风力机的所有轴承类型。近年来，圆柱滚子轴承和圆锥滚子轴承的到了成功的处理和使用。
In order to achieve the best performance of ***, black oxidation treatment is recommended for both inner and outer rings and rolls. Black oxidation can be applied to all bearing types of large wind turbines. In recent years, cylindrical roller bearings and tapered roller bearings h***e been successfully treated and used.
轴承座上中部和轴承座外侧（朝向辊头）注入的润滑脂不能很好地进入轧机轴承，容易丢失，导致轴承在轧制过程中工作面油质bu良，导致轴承早期失效。
The lubricating grease injected into the middle part of the bearing seat and the outer side of the bearing seat (towa*** the roller head) can not enter the rolling mill bearing well and is easy to be lost, resulting in good oil Bu in the working face of the bearing during rolling process, leading to early failure of the bearing.
为此，对轴承座油路进行了改进，在INA轴承座内侧（朝向辊体）增加了喷油嘴，提高了注脂效果。轴承润滑良好。大多数轧钢机现在使用润滑脂润滑。由于立磨的结构，使轴承在轧辊转动时使用寿命延长。
For this reason, the oil circuit of bearing seat was improved, and the oil injector was added to the inner side of INA bearing seat (towa*** the roll body) to improve the grease injection effect. The bearings are well lubricated. Most rolling mills now use grease lubrication. Because of the structure of the vertical mill, the service life of the bearing is prolonged when the roll rotates.
根据主机部件的要求注入规定的润滑脂或润滑剂。
Inject the specified grease or lubricant according to the requirements of the main engine parts.
装配大轴承及轴承与轴、座孔间隙大的产品时，bi须用油浴加热轴承，油浴温度约80℃。
When assembling large bearings and products with large clearance between bearings and axles and seat holes, Bi must use oil bath to heat bearings, and the oil bath temperature is about 80 C.
拆卸INA轴承时，bi须使用专用绘图工具。严禁用铁制工具直接敲打轴承。
When disassembling INA bearings, Bi must use special drawing tools. It is strictly forbidden to tap bearings directly with iron tools.
在装配和拆卸轴承时，应避免滚动部件和保持架受力或变形。
When assembling and disassembling bearings, force or deformation of rolling parts and cages should be ***oided.
