The slewing bearing is a special bearing that can withstand a large load such as large axial load, radial load, and tilting moment. Therefore, when selecting the slewing bearing, it must be strictly selected according to the calculation data!
In various types of construction machinery such as truck cranes and excavators, slewing bearings are important components for transmitting axial loads, radial loads and tilting moments between the turret and the chassis.
In the case of lighter loads, it works properly and is free to rotate. However, if the load is excessively heavy, especially when the lifting weight and the amplitude is too large, the slewing bearing is difficult to rotate, even it may be stuck and cannot be rotated.
When this happens, Xuzhou Wanda Slewing Bearing proposes to reduce the amplitude, adjust the legs or move the chassis position in time to tilt the body to help achieve the revolving motion of the heavy objects, complete the scheduled lifting and other operations, and avoid damage to the slewing bearing.
The second is friction. For many mechanical devices, friction is a key factor affecting the service life. The same is true for slewing bearings. Wear due to friction is a major factor in the reduction in the use time of the slewing ring.
In short, in order to ensure the normal use of the slewing ring, the user should always pay attention to the maintenance of the bearing when using it, regularly apply the lubricating oil, and do not let the bearing overload operation for a long time.
