Main lubrication methods for bearings: Oil lubrication and grease lubrication

Germany – Today, the best producer and seller for bearings such as SKF bearings and NSK bearings would teach us the main methods and principle of bearing lubrication. These methods for bearing lubrication could be divided into two main types which are grease and oil lubrication. In order to make bearings play well function, bearing technician should first select suitable lubrication method which could meet with the proper conditions and purpose. If the factory could only consider lubrication, the oil lubrication could be the best choice. However, the grease lubrication could help us simplify the around bearing structure. Now, let us begin our detailed description about the comparison between Grease and oil lubrication:

The first method the website http://www.hk-nkf.com/ wants to introduce all of the engineers is the grease lubrication. The advantage of grease lubrication is that once filling for grease can last a long time without refilling. On the other hand, the structure of its sealing device is relatively simple and therefore it has been widely used. The lubrication method of grease could be that the grease would be pre-filled into the sealed device into the bearings such as skf bearings. However, the worker should also fill a certain amount of grease inside the housing and replace them for a certain period of time.

In addition, for the machines which have many mechanical bearings which require lubrication, the worker could also adopt centralized greased way which lubrication parts are connected with pipes.

On the other hand, the technicians should also consider the amount of grease filling. The grease filling volume in the housing is one third of the volume of the housing. If the filling volume is excessive, the grease would have deterioration due to mixing heat. The factory worker should pay more attention to this point. However, for low-speed bearings, the factory could fill great amount of grease to prevent intrusion of outside objects.

On the other hand, the bearing technician should know that the supplementary and replacement of grease has a close relationship with the lubricating methods for bearings such as fag bearings . No matter what methods the factory has applied, the employee must use clean grease and pay attention to prevent the intrusion of foreign matters. The grease which the worker would add should be the same brand. When the worker is adding the grease, it is particularly important to ensure that the new grease should be surely added into the bearings inside.

The other sort the expert want to introduce with the factory technician is the oil lubrication. As all of the technician know, the oil lubricated method for bearings such as skf bearings is suitable for high speed bearings such as nsk bearings and this kind of methods could have the high resistance ability to high temperature. On the other hand, it could also effectively reduce the vibration and noise. However, the oil lubricated method could be mainly used for the occasions which grease lubrication is not applicable.
