Is more grease better?

2023-04-11

The movement of lubricating grease in bearings can be roughly divided into two stages: the running in period and the balance period.

During the running in period of the bearing, excess lubricating grease accumulates in the cavity of the cage or bearing, and accumulates on the periphery of the rolling element. If there is excessive lubricating grease, it will cause the temperature of the bearing to rise, and even burn (destroy) the bearing. Due to factors such as the structure of the bearing, the quality of the lubricating grease, and the amount of grease filled, the running in period may last for tens of minutes or several hours. When the excess lubricating grease in the bearing is squeezed out, a small amount of remaining lubricating grease on the rolling element, raceway, and cage will form an oil film and enter normal operation. At this time, if the amount of grease filled is appropriate, the temperature of the bearing will gradually decrease and reach basic stability, entering the equilibrium period.

Therefore, the above factors should be considered when selecting the amount of lubricating grease, and it is not that the more grease, the more guaranteed the lubrication performance. Overfilling with lubricating grease can increase frictional resistance, increase temperature, and lead to grease leakage, deterioration, loss of performance, or failure. It is also easy to pollute the surrounding environment, especially for applications such as papermaking machinery and food machinery, which are not allowed.

Whether cultivating soil or mowing grass, a disc rake must remove heavy and laborious soil, dust, and more. In working condition, the disc rake bearing must come into contact with these substances and withstand both heavy and impact loads. During the flushing process, the bearing seals must be kept free of water and detergent, and lubricants must not leak out.
