4 points to reveal the installation and maintenance skills of crane slewing bearings

Slewing bearings are widely used in various mechanical equipment. In recent years, they have also shown good advantages on marine cranes. Everyone knows the models and specifications of crane slewing bearings, and also knows that correct installation and reasonable maintenance can increase the service life of slewing bearings and greatly improve work efficiency. So today, Hengguan editor will explain to you the correct installation and maintenance skills of crane slewing bearings.

1.Ensure that the new bearing is filled with 2# lithium-based grease every 100-300 hours, and then ensure that it is filled once a quarter.

2. When installing the slewing bearing, the main requirements are good concentricity and appropriate working radial clearance. It should not be too large or too small. Too small will increase friction and affect the service life. Too large will cause the slewing bearing to be loose and vibrate more, affecting the service life of the slewing bearing. The sealing device should be sufficient to prevent dust and moisture from penetrating.

3. Before installing the slewing bearing, read the installation instructions carefully and strictly follow the installation steps. If the installation steps are incorrect, it may cause failure or the installation quality is unqualified.

4. The key points of slewing bearing maintenance include timely checking whether the sealing device is damaged, timely replacing the grease, and timely repairing the slewing bearing if there is abnormal noise.

If the slewing bearing makes noise and unknown vibration, it is necessary to stop the machine and contact the slewing bearing manufacturer in time to let more professional people handle and solve it, so as to avoid damage to the slewing bearing and affect the work.
