Lubrication has a crucial impact on the operation and lifespan of rolling bearings. Lubricating grease is made from base oil, thickeners, and additives. The performance of different types and brands of lubricating grease with the same type varies greatly, and the allowable rotation limit varies. It is important to pay attention when selecting.
The performance of lubricating grease is mainly determined by the base oil. Low viscosity base oils are generally suitable for low temperatures and high speeds; High viscosity is suitable for high temperatures and loads. Thickener also affects lubrication performance, and the water resistance of thickener determines the water resistance of lubricating grease. In principle, lubricating greases of different brands cannot be mixed, and even lubricating greases with the same thickener can have negative effects on each other due to different additives.
Grease lubrication is the direct application of lubricating grease between the moving surfaces of rolling bearings. However, when inputting lubricating grease to the raceway and sliding working surface of bearings, the following 5 principles must be followed:
(1) The lubricating grease must penetrate the working surface of the rolling bearing and the internal gaps of the bearing in order to fully lubricate the grease.
(2) A certain amount of lubricating grease should be retained on the working surface of the bearing for a certain period of time, but it is also necessary to prevent excessive loss of lubricating grease.
(3) The flow direction of lubricating grease input and discharge should be consistent with the sealing requirements, which is conducive to the discharge of invading pollutants.
(4) On the premise of ensuring good lubrication of rolling bearings, try to reduce the amount of lubricating grease as much as possible.
(5) Install an outlet hole at the end of the grease flow direction to allow the newly replenished grease to squeeze out the old grease and ensure good lubrication. Special reminder, when lubricating constant cross-section rolling bearings with grease, it is important to pay attention to the working temperature range of the rolling bearing grease. If it is not within the appropriate temperature range, the effect will be counterproductive.
