How to select lubricating grease for motor bearings running at high temperature
Author:admin Date:2023-03-03
With the continuous development of industry and manufacturing, mechanical equipment is also more advanced and efficient. Correspondingly, the requirements for lubricating grease are more stringent. It must be understood that in order to meet the requirements of various industrial equipment, various special greases are also available.
The special grease on the market generally refers to that it can provide good lubrication to the motor, gear, chain, motor bearing and other equipment and components under high temperature, high speed, low temperature, corrosion and other conditions, and has a slight repair effect on the surface, shock absorption and noise reduction, reduce the wear of lubricating parts and other functions, maintain the equipment performance and extend the service life of the equipment. High temperature and high speed motor bearing grease is a kind of mixed base oil, specially made with anti-wear ion, anti-oxidation, anti-corrosion and other additives. It is a kind of high-temperature grease developed for long-term high-temperature and high-speed working motor bearings.
You may have questions about whether ordinary grease can be directly used for machinery such as motor bearings? The answer is: Not recommended! When the motor and bearing equipment rotate at high speed, the friction will generate heat. If the working time is long, the temperature will not be too high. The ordinary lubricating grease will evaporate and lose its lubrication effect, which will eventually lead to bearing damage, or even burn the machine in serious cases! If your motor equipment increases friction and wear due to the high temperature evaporation of lubricating grease, it is recommended to replace it with a suitable high-temperature lubricating grease immediately to avoid the equipment burning out.
If you think that the grease you use is not suitable, how should we replace the new grease correctly after buying a new high-temperature grease? If you want to replace the original grease with a new type of grease, please clean the original grease in the equipment or lubricating parts thoroughly before adding new grease. The same is true for equipment maintenance. It is necessary to clean the residual grease and refill it.
