Strictly speaking, determining the time to replace an energy-efficient motor bearing is a more complicated problem, and it is difficult to answer with a simple data. Because it involves the quality of the original bearing, the quality of the grease, the amount of running time per day, the size and smoothness of the load and many other factors. Therefore, it is generally determined whether to replace the motor bearing according to the actual situation of the monitoring of the motor bearing in use. For example, when it is found that the bearing temperature is significantly increased, and obvious abnormal noise and large vibration occur, it is necessary to consider disassembling the motor to check whether the bearing is damaged or worn. The grease is seriously discolored or can be seen to have metal powder, indicating that the bearing has been seriously worn. Generally, the grease should be cleaned before the damage can be observed. Then decide whether to replace the bearing according to the condition of the inspection.

If you must specify a replacement cycle (because in some use cases, if you decide to replace it after non-replacement, it may seriously affect the production, or even cause a large loss, so the equipment should be repaired regularly, including mandatory Stipulates the replacement of wearing parts, it is recommended to use bearings that are used more frequently (such as more than 7h per day) or load fluctuations (especially during the impact load phase where there is an overload in each fluctuation cycle). The replacement cycle is about 1 year; the shorter replacement period and lighter load regulation period is between one and a half years to two years.
