Issues regarding bearing lubrication
Thread Content
Our factory currently has a pump; since the medium used is hot water at 90 degrees Celsius, the bearing grease often fails due to the high temperature, resulting in damage to the bearings. I was thinking that replacing butter with molybdenum disulfide might solve this problem.
It can be solved by replacing it with a bearing housing equipped with a water jacket; or cooling the mechanical seal can also work, to prevent heat transfer
Using molybdenum disulfide can help improve the situation; another option is to choose a lubricant in liquid form and install an automatic lubrication system, which isn’t very costly either.
90 degrees is not a very high temperature, and the cause of bearing failure is not necessarily related to the lubricant used. However, it is recommended to use lubricating oil instead next time the bearings are replaced.
A 90-degree angle of the medium shouldn’t be the main factor affecting performance; I think the dripping point of lithium-based grease is around 170 degrees. Avoid using calcium-based or sodium-based greases – opt for lithium-based grease instead.
For rolling bearings, sodium-based grease can be used, with a maximum operating temperature of 110℃
High-temperature grease SHC220, etc~~
Are they back-to-back bearings of the positioning end 73 series?
