Gearless Cross-Roller Turntable Bearing

The installation of a gearless cross-roller slewing bearing is a critical step that must be carried out with care to ensure proper operation and long-term stability.

The installation of a gearless cross-roller slewing bearing is a critical step that must be carried out with care to ensure proper operation and long-term stability. The following are the general steps and precautions for installing a gearless cross-roller slewing bearing:

Step 1: Preparation

Inspect the bearing and its surrounding environment:

Before beginning installation, inspect the bearing and the mounting area to ensure they are free of visible damage or contamination. Verify that the work area is clean and free of debris and dust.

Prepare the necessary tools and equipment:

Ensure that you have the appropriate tools and equipment, including lifting gear, positioning tools, lubricants, and measuring instruments.

Step 2: Bearing Lift and Positioning

Using lifting equipment:

Using appropriate lifting equipment, such as a crane or hoist, carefully lift the gearless cross-roller slewing bearing and ensure it remains level.

Locating bearing:

Carefully position the bearing in its mounting location, ensuring that its base is aligned with the supporting structure.

Step 3: Connect External Devices

Connect the drive mechanism (such as an electric motor or a hydraulic device):

If your application requires the bearing to rotate or move, ensure that the external drive mechanism is properly connected so that the bearing operates as intended.

Connect hydraulic or pneumatic lines (if applicable):

If the application requires hydraulic or pneumatic supply, ensure that the piping is properly connected and perform the necessary leak tests.

Step Four: Adjustment and Lubrication

Adjust the bearing:

As needed, perform preliminary bearing adjustments to ensure that, once installed, the bearings meet the specified performance requirements.

Lubrication:

Lubricate bearings properly in accordance with the bearing manufacturer’s recommendations. Use the appropriate type and quantity of lubricant to ensure the lubrication system functions correctly.

Step Five: Inspection and Testing

Check the alignment and level of the bearings:

Use a level and measuring tools to check the bearing’s horizontal alignment and concentricity. The accuracy of these parameters is critical for the bearing’s proper operation.

Perform bearing testing:

After installation, perform a free‑rotation test on the bearing to ensure it spins smoothly without any abnormal noise or vibration.

Step Six: Secure

Fixed:

Once it has been confirmed that both the bearing installation and testing meet the required specifications, secure the bearing to the supporting structure, ensuring it remains firmly in place.

Step Seven: Monitoring and Maintenance

Monitoring Operations:

After the bearing is put into service, regularly monitor its operating condition. If any abnormalities are detected, take timely maintenance measures.

Regular lubrication:

According to the manufacturer’s recommendations, perform regular lubrication and maintenance on the bearings to ensure their long-term stable operation.
