2025-02-26

Everyone knows that during the use of slewing ring, well-maintained slwing ring have a long life, so most people have such a question, how should they be maintained? The following editor will give you a detailed interpretation of the relevant content of slewing bearing maintenance.

  • Slewing bearing (slewing ring) maintenance and care:

There is a common misunderstanding among customers about the maintenance of slewing bearing. They think that the lubricating oil of the slewing bearing has the same lubrication cycle as the big and small arms, and should be applied every day. In fact, this action has the opposite effect. If the lubrication cycle is too short, there will be too much lubricating oil in the slewing ring, which will break the dust ring and leak out. When there is leakage, impurities will also enter the slewing ring, thus damaging the normal operation of the slewing bearing. The general lubrication interval of the slewing bearing is about every 250 hours. Apply butter to the upper and lower parts at the same time, and rotate the machine while applying. Apply a full gun of lubricating oil every 15°. In different applications, the lubrication cycle can be appropriately adjusted according to your work intensity. Generally, lubrication once a week is sufficient.

As a precision bearing supplier and bearing manufacturers with more than ten years of experience, DZE has rich experience in bearing maintenance.


  • Lubrication of the swing motor:

The maintenance period of the lubricating oil of the swing motor is 1000 hours. In daily operation, we need to observe the amount of the swing lubricating oil from the dipstick. In some cases, we will find abnormal loss of lubricating oil. We need to open the large gear ring window to check whether the lubricating oil leaks into the large gear ring cavity through the sealing ring. In addition to the above maintenance methods, we also need to regularly check whether the gear ring bolts are loose and whether the slewing bearing dust ring is damaged. Some fine cracks on the outside will be covered by mud. If these cracks are not discovered in time, it may cause the turntable to crack, or even cause accidents.
