南京NSK轴承的光滑方法一般分为润滑脂和润滑油两大类。为了充分发挥轴承的作用，根据使用的调节和减速及操作意图，选择一种平滑的方法是很重要的。图中示出了润滑油的优点和缺点以及润滑油的光滑性。
The ***ooth method of NSK bearing in Nanjing is generally divided into two categories: grease and lubricating oil. In order to give full play to the role of bearings, according to the use of adjustment and deceleration and operation intent, it is important to choose a ***ooth method. The advantages and disadvantages of the lubricating oil and the ***oothness of the lubricating oil are shown in the diagram.
光滑润滑脂是由基础油、增稠剂和添加剂组成的平滑剂。在选择南京NSK轴承油脂时，应选择非常合适的轴承条件，因为不同的商标，在功能方面会有很大的不同，所以在选择时应注意。
***ooth grease is a ***oothing agent composed of base oils, thickeners and additives. When choosing Nanjing NSK bearing grease, we should choose very suitable bearing conditi***, because different trademarks, in terms of function will be very different, so we should pay attention to the choice.
轴承润滑脂一般采用钙基润滑脂、钠基润滑脂、钙钠基润滑脂、锂基润滑脂、铝基润滑脂和二硫化钼基润滑脂。轴承中填充的光滑润滑脂的量适合于轴承的内部空间的1／2-1／3的填充。高速率应降低到1/3。过多的脂肪会升高温度。
Bearing grease generally uses calcium-based grease, sodium grease, calcium-sodium grease, lithium grease, aluminum grease and molybdenum disulfide grease. The amount of ***ooth grease filled in the bearing is suitable for filling 1 / 2-1 / 3 of the internal space of the bearing. The high rate should be reduced to 1/3. Too much fat will raise the temperature.
根据操作温度选择润滑脂时，首要项指标是滴点、氧化稳定性和低温性能。该落点可用于评价南京NSK轴承的高温性能，轴承的工作温度应小于10～20％。润滑脂的使用温度应在20-30度以下。根据轴承载荷，选择润滑脂时应选用低浸入润滑脂。在高压下工作时，除了针穿透外，还具有较高的油膜强度和极压功能。钙基润滑脂不溶于水，适合于干燥和较少的水。
When choosing grease according to the operating temperature, the primary indicators are dropping point, oxidation stability and low temperature performance. The drop point can be used to evaluate the high temperature performance of NSK bearing in Nanjing, and the working temperature of bearing should be less than 10 ~ 20%. The use temperature of grease should be below 20-30 degrees. According to bearing load, low immersion grease should be used when selecting grease. When working under high pressure, besides needle penetration, it also has higher oil film strength and extreme pressure function. Calcium based grease is insoluble in water, suitable for drying and less water.
在高速和高温条件下，润滑脂不够光滑。通过循环润滑油，它可以带走大量的热量。
Under high speed and high temperature conditi***, grease is not ***ooth enough. By circulating lubricating oil, it can take away a lot of heat.
粘度是光滑油的一个重要特征。粘度直接影响光滑油的流动性和在相互冲突的表面之间形成的油膜厚度。在南京NSK轴承的工作温度下，光滑油的粘度一般为12-15度。速度越高，粘度越低。负荷越重，粘度越高。常用的润滑油纯机械油、高速机械油、汽轮机油、压缩机油、变压器油、汽缸油等。
Viscosity is an important characteristic of ***ooth oil. Viscosity directly affects the fluidity of ***ooth oil and the oil film thickness formed between conflicting surfaces. Under the working temperature of NSK bearings in Nanjing, the viscosity of ***ooth oil is generally 12-15 degrees. The higher the speed, the lower the viscosity. The he***ier the load, the higher the viscosity. Commonly used lubricant pure mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc.
