The intrusion of dust and impurities in mechanical operations is inevitable. As a bearing used in large or heavy machinery and equipment, the slewing bearing itself has mounting holes, lubricating oil holes and sealing devices, but it will still be affected by the complex environment. Once improperly maintained, it may cause debris to enter the slewing ring along with the rotation of the mechanical parts, increase the friction between the slewing ring and related accessories, and cause activity jams, and may even cause the machine to stop running. In this way, operation and management personnel are required to be proficient in cleaning methods and clean up impurities in a timely manner to ensure that the machinery is in production.

The dust deposited in the raceway of the slewing bearing could not be cleaned up, which caused the oil injection pipe to be blocked and the rollers stuck in the raceway. Use temporarily added auxiliary equipment to inject high-pressure descaling liquid into the slewing ring. Through repeated rotations, the friction pairs of the slewing ring can move relative to each other to clean up the grease and dust deposited in the raceway. After cleaning, pour engine oil into the slewing ring to clean up the descaling liquid.

It is necessary to check the related accessories of the slewing ring regularly. It is necessary to prevent damage to the accessories or the intrusion of impurities caused by improper use of lubricating oil.
