Determining the bearing life cycle is crucial for users.
This decision involves a comprehensive consideration of the machine type, operating environment, and reliability requirements.
For infrequently used equipment and devices, a life cycle of 3,000 to 30,000 hours is recommended.
For machines with short-term or intermittent use, a life cycle of 3,000 to 8,000 hours is recommended.
For machines with intermittent use, where interruptions could have serious consequences, a life cycle of 8,000 to 12,000 hours is recommended.
For machines operating eight hours per day but not at full capacity, a life cycle of 10,000 to 25,000 hours is appropriate.
For machines operating eight hours per day at full capacity, a life cycle of 20,000 to 30,000 hours should be considered.
For machinery operating 24/7, if the consequences of interruptions are not a concern, a lifespan of 40,000 to 50,000 hours is ideal; however, if interruptions could cause problems, a lifespan of up to 100,000 hours should be considered.
Furthermore, bearing lifespan is affected by operating duration and load.
In addition, incorrect installation, insufficient lubrication, bearing fatigue, and contamination are all key factors affecting bearing lifespan.
Specifically, incorrect installation accounted for 16%, lubrication issues 36%, bearing fatigue 34%, and contamination 14%.
Therefore, selecting the appropriate bearing lifespan and replacement interval is crucial.
