Proper lubrication and maintenance can give full play to the high service life of Koyo bearings.
1. Grease lubrication
The relubrication of Koyo bearings is carried out during the planned equipment shutdown and Periodic Lubrication supplemented regularly. At the same time, the old grease is removed or squeezed out through the oil drain air.
Wipe the grease nipple clean before adding fresh grease. If the Koyo bearing housing does not have an oil filler, open the Koyo bearing housing cover or end Periodic Lubrication cover to take out the old grease. After cleaning, add fresh grease of the same model.
2. Lubricating oil lubrication
Regularly check the oil level and quality of lubricating oil. Generally, the normal oil level should be Periodic Lubrication within 1 / 3-2 / 3 of the equipment oil level window or mark.
The oil replenishment mode is the oil cup, and the displayed oil level only represents the oil Periodic Lubrication replenishment capacity, while the oil level of Koyo bearing box meets the operation requirements. If the oil level in the oil cup is lower than 1 / 4 of its total volume, oil replenishment can be considered.
Check and replenish oil methods. Periodic Lubrication Take a small amount of lubricating oil as a sample and compare it with fresh lubricating oil.
Competent units can consider oil quality test to ensure that the oil quality is qualified. If the sample looks like a cloud, it may be the Periodic Lubrication result of mixing with water, which is often called oil emulsification. At this time, the lubricating oil should be replaced.
it may indicate that the lubricating oil has begun to carbonize, and the old lubricating oil should be completely replaced. If possible, flush the oil circuit with fresh lubricating oil. When replacing the lubricating oil, ensure that the new and old models of the replaced lubricating oil are the same, and supplement it to meet the required oil level.
Use the oil bath lubrication system. If the oil temperature is below 60 ℃ (140 ° f) and the Periodic Lubrication lubricating oil is not polluted, replace the lubricating oil once a year. If the oil temperature is 60-100 ℃ (140-210 ° f), the lubricating oil needs to be changed four times a year.
If the oil temperature is 100-120 ° C (210-250 ° f), the lubricating oil needs to be changed once a month. If the oil temperature is above 120 ℃ (250 ° f), the Periodic Lubrication lubricating oil needs to be changed once a week.
Proper installation and maintenance is an important factor for the normal operation of Koyo bearings. At the same time, attention must be paid to maintaining the cleanliness of Koyo bearings.
Koyo bearings must be protected from pollutants and moisture, and must be correctly installed and lubricated. In addition, the design of Koyo bearing arrangement, the condition of oil seal, the form and replacement cycle of lubricant and special maintenance also play an important role, which must be paid attention to.
