Unusual noises from bearings: 5 points to check before replacement.
If it recurs even after replacing with the same model, the cause may be lubrication, installation, gaps, or surrounding components. We will support the diagnosis of abnormal noises.
When a machine emits unusual sounds like "goro goro" or "kii kii," it is common to first consider replacing the bearings. However, the cause of the unusual sounds is not always limited to the bearings themselves. Factors such as lubrication conditions like grease, improper installation, selection of internal clearances, and wear of the shaft or housing can also play a role. Therefore, simply replacing it with the same model may lead to recurrence of the issue. When unusual sounds occur, it is important to check the model's suffix code, usage conditions, timing of occurrence, replacement history, and the condition of surrounding components. At Bandai, based on our approximately 65 years of experience as an authorized distributor of NSK bearings, we organize model and usage conditions and propose reviews of clearances, seals, and grease specifications, as well as alternative products. If you are troubled by unusual sounds or short bearing life, please feel free to consult with Bandai. *This type of response is just a small part of the efforts that Bandai engages in daily.
