The slewing bearing is a large bearing that can bear comprehensive load. It can bear large axial and radial load and overturning moment at the same time. slewing bearing is generally equipped with installation hole, internal gear or external gear, lubricating oil hole and sealing device, so it can make the design structure of the host compact, simple guidance and easy maintenance.

What items are included in the routine inspection of slewing bearings?

1. Regularly check the flexibility of the rotation; if noise and impact are found, it should be stopped immediately for inspection, troubleshooting, and dismantling and inspection if necessary;

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

3. Regularly check the integrity of the seal. If the sealing belt is found to be damaged, it should be replaced in time. If it is found to fall off, it should be reset in time.

How to check the slewing bearing?

1. Before each crane works or at least once a week, visually check the bolts on the slewing bearing;

2. After the slewing bearing works for 100 working hours for the first time, check whether the bolts are loose, and check again at the 300th working hour; after that, check every 500 working hours; the inspection interval should be shortened under severe working conditions. If the bolts are found to be loose during the inspection, please stop the construction operation, and immediately contact the local after-sales service department, and the factory or professional technicians will check and decide whether to disassemble and inspect immediately;

3. The slewing bearing should be filled with lithium-based grease before installation;

4. When replacing the bolts, wipe the bolts clean, apply thread tightening glue, and then tighten them;

Use the crane in accordance with the requirements of the operation manual and the lifting performance table, or check the fastening bolts regularly as required, so as to avoid the risk of fatigue failure of the bolts.

How to properly use the tooth surface of lubricating slewing bearing?

The 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, the anti-rust oil should be coated in time. In addition, in use, the slewing bearing is prevented from being exposed to direct sunlight. It is forbidden to rinse the slewing bearing directly with water to prevent water from entering the raceway and prevent hard foreign objects from approaching or entering the tooth meshing area.
