What Is the Proper Usage of Crossed Roller Bearing Grease?


Crossed roller bearings use lubricating grease, which is a thick semi-solid grease that acts as a lubricant and a sealant for the frictional parts of the bearing. It is also used on metal surfaces to fill gaps and prevent rust. The purpose of using bearing grease is to create a thin layer of lubricating oil film between the rolling and sliding surfaces of the bearing to prevent direct metal-to-metal contact, thereby reducing internal friction and wear, preventing seizure. So what is the correct use of crossed roller bearing lubricating grease?


The amount of lubricating grease added to the crossed roller bearings should be appropriate


Excessive grease will increase the frictional torque, raise the temperature, and increase the consumption of grease; and insufficient grease will lead to unreliable lubrication and result in dry friction. Generally, the appropriate amount of grease is 1/3 to 1/2 of the total clearance volume inside the bearing. However, depending on the specific situation, grease can sometimes be applied to the edge of the bearing to achieve cavity lubrication.


Pay attention to avoid mixing different types, grades, and new and old lubricating greases for crossed roller bearings


Avoid interchanging containers and tools for lubricating grease, otherwise, it will result in adverse effects such as a decrease in the dripping point of the grease, an increase in the cone penetration ratio, and a decrease in mechanical stability.


Pay attention to replacing new grease for crossed roller bearings


Since the types and quality of grease are constantly improving and changing, when old equipment is changed to new lubricating grease, it should be tested first before being put into formal use. When replacing, the waste lubricating grease should be removed and the components cleaned. When adding grease, the waste lubricating grease should be squeezed out until new lubricating grease appears at the grease outlet.


Pay attention to the management of the lubricating grease addition process for crossed roller bearings


Prior to receiving and adding lubricating grease, strict attention should be paid to the cleanliness of the containers and tools. The grease supply port on the crossed cylindrical roller bearings equipment should be wiped clean in advance, and mechanical impurities, dust, and sand particles should be prevented from mixing in.


Pay attention to the timely replacement of seasonal grease for crossed roller bearings


If the crossed cylindrical roller bearings equipment is located in an environment where there is a large temperature difference between winter and summer, if summer grease is used in winter, or vice versa, the results will be counterproductive.


Pay attention to regularly adding and replacing lubricating grease for crossed roller bearings


The time for adding and replacing lubricating grease should be determined based on the specific usage situation, ensuring reliable lubrication and avoiding waste.


Do not use wooden or paper containers to package lubricating grease for crossed roller bearings


Avoid hardening of the lubricating oil, mixing with water, or being contaminated and deteriorating, and store it in a cool and dry place.


To fully utilize the role of crossed roller bearings, suitable lubrication methods and high-quality lubricating grease should be selected. The noise and vibration of crossed roller bearings directly affect the use of industrial robots. The quality and characteristics of lubricating grease are the main factors affecting the noise and vibration of bearings. The addition of lubricating grease can form a layer of thick, continuous, and stable lubricating oil film on the surface of the bearing raceway, reducing the amplitude, thus reducing the vibration velocity and acceleration, and effectively suppressing crossed cylindrical roller bearings noise and vibration.
