Product details

    Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

Routine Inspection of Slewing Bearings

1. Check the flexibility of the rotation on schedule; if noise (dB) or impact is found, it should be stopped immediately for inspection, troubleshooting, and dismantling if necessary;

2. Regularly inspect whether the rotating ring gear is cracked or damaged, and whether the meshing tooth surface has occlusion, gnawing, tooth surface peeling, etc.;

3. Check the condition of the seal on time. If the seal is found to be damaged, it should be replaced in time. If it is found to be dropped, it should be reset in time. The tooth surface of lubriCATion slewing bearing ring gear has been coated with anti-rust oil before leaving the factory. The validity period of this anti-rust is generally 3 to 6 months. After the validity period is exceeded, anti-rust oil should be applied in time.

Lubricate the raceway of the slewing bearing

The raceway must be filled with lubriCATion grease on schedule according to the working environment. After 50 working hours for the first time, the raceway should be filled with lubricating oil (LubriCATing oil), and then every 300 working hours after that. The slewing bearing must be filled with grease before and after being placed for a long time. If steam jet cleaners or stationary water jets are used to clean the crane, care must be taken to ensure that water does not penetrate (Osmosis) the slewing ring connections, and then the slewing ring connections must be lubricated.

Filling the grease should be carried out with the slewing bearing rolling slowly. When the lubriCATion grease overflows from the seal, it indicates that the filling is completed. The overflowing grease will form a film and act as a seal.
