What is a slewing bearing ?
The slewing bearing for excavator (exemple) is a center part of the machine. It ensures the connection between the frame and the turret while allowing a 360 ° rotation. This is the case particularly for track excavator, wheel excavators and mini-excavators. Its use is different for graders. It will have a directional function for these tools.
The slewing ring bearing has a moderate axial stiffness as the diameter is large relative to its section. After many working hours, this wearing part have to be change. This is due to the fact that it is subject to great stresses in particular the rolling swing bearing operations, in support during splitting operations by hydraulic hammer. Deformations appear at the raceway causing hard spots or even blockages. Over time, the serration of the ring wears and takes more and more game.
Scheduled maintenance is essential on these organs. The frequency of lubrication of the raceway and of the serration varies depending on the use and the working environment. This will determine a longer or shorter lifetime. In the case of heavy use, the manufacturers recommend lubrication every 50 hours (instead of 150 hours), mainly in very dusty and humid areas.
To avoid problems, it is important to carry out preventive checks on the slewing bearing.
