Slewing ring in real industrial applications is very wide, the tower crane is simultaneously subjected to axial force, overturning moment, radial force and take two important section dedicated member relative rotation. With the rapid development of the machinery industry, slewing bearings in marine equipment, engineering machinery, light machinery, metallurgical machinery, medical equipment, industrial machinery and other industries it has been widely used. So in the course, do not forget to slewing ring routine maintenance.

One, we must first know, slewing ring raceway inside the first refilled with new grease works in it will be carried out after one hundred hours. After each run four hundred hours on the check and the right amount of lubrication to keep the rotary bearing in good lubrication condition. Such as tropical, humidity, dust, big temperature difference and under these special circumstances, should shorten continuous lubrication cycle, and make a record.

Two, secondly, slewing ring for the first time one hundred hours after the operation, but also check the bolt preload, after every 500 hours of operation check again to see whether to maintain adequate preload.

Three, slewing ring seal also often check whether the situation, if it is found damaged seal should be replaced, should be found to seal off the reset, to prevent rainwater from entering the raceway lead to grease failure. 

Four, every 10 days slewing bearing tooth surface is necessary to clean and replace the grease will permit iron, gravel and other hard foreign objects close to or into the meshing zone.

Five, different types of grease or grease from different manufacturers can not mix, so as to avoid premature failure of grease.

In addition, in the course of slewing bearings, slewing bearings Do not use water erosion, prevent water from entering the raceway caused by rust; hard to prevent foreign objects close to or into engagement area, in order to avoid tooth injuries or unnecessary trouble.
