Self-Lubricating Bearing Industry knowledge
What are the differences between the different lubrication methods of Self-Lubricating Bearing?


There are several different methods of lubrication for self-lubricating bearings, each with specific advantages and limitations. The most important differences between these methods include:
Dry/No Lubrication: Some self-lubricating Oilless Sliding Bearings are designed to operate without external lubrication. These bearings often contain solid lubricants, including PTFE (polytetrafluoroethylene) or graphite, in their construction, which provide low friction characteristics and allow the bearings to self-lubricate at certain operating points. This method eliminates the need for routine lubrication maintenance and reduces the risk of contamination or oil leakage. However, it may hit a snag in programs that are too fast or too hot.Additionally, certain designs of self-lubricating bearings incorporate a brass bush for enhanced performance in specific applications.
Grease Lubrication: In this method, grease is applied to the bearings to provide lubrication. Grease acts as a stock, distributing lubrication to the bearing surface as needed. Grease lubrication provides an excellent seal as it prevents contaminants from entering and maintains lubrication within the bearing. It can also withstand higher temperatures than dry lubrication. Its limitation is that it requires periodic maintenance to monitor grease condition and refill when necessary.
Oil Lubrication: Self-lubricating bearings can also be designed to be oil lubricated. In this technology, bearings are designed with oil grooves or pockets to retain lubricating oil. Oil is transported to the bearing surface by capillary action or the movement of the bearing. Oil lubrication provides effective cooling and can handle better speeds and loads. However, continuous oil supply and regular monitoring are required to ensure adequate lubrication.
Solid lubricating film: Some self-lubricating Sliding Bearing contain a stable lubricating film on their surface along with molybdenum disulfide (MoS2) or tungsten disulfide (WS2). These films provide a low-friction layer that reduces wear and friction between the bearing and mating surfaces. Solid lubricating films are often used in applications where temperatures are too high or heavy loads, where other lubrication technologies may fail or degrade.This method is commonly used in applications such as those involving brass bush.
Each lubrication method has its own advantages and disadvantages, and the choice depends on each operating situation and application requirements.For self-lubricating bushings, the appropriate lubrication method can also be selected based on the operating environment and application requirements to ensure stable operation and long-term performance of the bearing system.
