滚动轴承的润滑主要是为了降低摩擦阻力 ,减轻磨损、减振 ,防止锈蚀和均匀散热等作用。常用的润滑剂有润滑脂 (黄油 )和润滑油。在使用过程中主要应注意以下两个方面问题 :一、润滑脂润滑应注意填充量滚动轴承采用润滑脂润滑便于密封和维护 ,方法简单且长期不必补充更换 (通常? Lubrication of rolling bearings is mainly to reduce frictional resistance, reduce wear, vibration, prevent corrosion and uniform heat dissipation and so on. Commonly used lubricants are grease (butter) and lubricants. In the process of using the main attention should be the following two aspects: First, the grease lubrication should pay attention to the amount of filling Roller bearing grease lubrication easy to seal and maintain, the method is simple and does not have to be replaced in the long term replacement (usually?
