Causes and Precautions of Abnormal Noise in Slewing Bearing Raceway

Abnormal noise in the slewing bearing raceway is usually caused by the following reasons

Improper design

The initial selection and design are problematic, and the actual load-bearing capacity requirement is not met.

Poor lubrication

The slewing bearing raceway needs regular lubrication. If the lubrication is poor or low-quality lubricating oil is used, the friction coefficient will increase, causing abnormal noise.

Improper assembly

If the slewing bearing is not installed correctly during assembly, such as being installed off-center or not parallel, it will cause raceway deformation and abnormal noise.

Poor sealing

The sealing of the slewing bearing raceway is not good, and it is easy to allow dust and moisture to enter, causing rust, wear, failure, and abnormal noise.

Bearing damage

Bearing service life expiry, damage, excessive wear, and other factors can lead to abnormal noise in the slewing bearing raceway.

Precautions for the Rotation Bearing Support Track

• Regularly check for abnormal noise in the slewing bearing raceway and address any problems in a timely manner.

• Use high-quality lubricating oil and replace it regularly according to the requirements.

• During installation, pay attention to correct installation according to the requirements and ensure control of raceway parallelism and deflection issues.

• Ensure proper sealing to prevent dust and moisture from entering the raceway.

• Regularly maintain and care for the slewing bearing, including lubrication, cleaning, and other measures, to ensure its normal operation.
