Be alert to distress signals emitted by bearings during equipment operation

The bearing system is essential for the normal and safe operation of equipment. Problems with the bearing system can manifest as minor bearing noise or, in more serious cases, mechanical seizure and damage to the entire equipment.

Over one-third of bearing system problems can be attributed to lubrication, with poor lubrication often caused by grease degradation and failure during operation.

To ensure the effectiveness of grease performance, the equipment's technical specifications specify a maximum operating temperature. Exceeding these temperatures can lead to both lubrication system failure and deterioration in the performance of bearing components.

Whether operating or testing, the operating temperature of the bearing system remains stable within a certain range. The stable bearing temperature for the same motor can vary depending on the operating environment. In high-temperature environments, the bearing system experiences elevated temperatures. To ensure the safety of the bearing system, high-quality, high-temperature resistant grease should be selected.

When the following situations occur, equipment users should closely monitor equipment operation to prevent further problems from spreading and worsening:

1. The equipment's bearing system experiences temperature instability, accompanied by varying degrees of noise. If the bearing system stabilizes after adding grease, this is considered normal; otherwise, necessary diagnosis and troubleshooting should be performed.

2. If grease deficiency persists, consider whether the equipment's bearing system has a serious oil leak. This can be assessed by measuring bearing temperature, but structural design issues may also be a possibility.

3. If irregular mechanical noise persists after improving the equipment's lubrication conditions, consider whether the rolling elements are damaged.
