Proper lubrication and maintenance can maximize the life of KOYO bearings.
1, grease lubrication
The relubrication of KOYO bearings is best carried out during the planned downtime of the equipment and is periodically replenished, while the old grease is removed or the old grease is squeezed out through the drain. Wipe the grease fittings clean before adding fresh grease. If the KOYO bearing housing does not have a grease fitting, the KOYO bearing housing cover or end cap should be opened to remove the old grease and, after cleaning, replenish the same type of fresh grease.
2, lubricating oil lubrication
Regularly check the oil level and oil quality of the lubricating oil. Under normal circumstances, the normal oil level should be within the range of 1/3-2/3 of the equipment oil level window or mark. The oil filling method is oil cup, the oil level shown only represents the oil replenishing capacity, and the oil level of KOYO bearing housing is to meet the operation requirements. The oil level in the oil cup is less than 1/4 of its total volume.
Check and replenish the oil method, take a small amount of lubricating oil as a sample and compare it with fresh oil. The competent unit can consider the oil quality test to ensure the oil quality is qualified. If the sample looks cloudy, it may be the result of mixing with water, which is commonly referred to as oil emulsification. At this point, the lubricant should be replaced. If the sample is darkened or thickened, it may indicate that the lubricant has begun to carbonize and the old lubricant should be completely replaced. If possible, flush the oil line with fresh oil. When changing the lubricating oil, make sure that the new and old models of the replaced oil are the same and supplement the required oil level.
Use an oil bath type lubrication system. If the oil temperature is below 60 ° C (140 ° F) and the lubricant is not contaminated, replace the lubricant once a year. If the oil temperature is between 60-100 ° C (140-210 ° F), the lubricant needs to be replaced four times a year. If the oil temperature is between 100-120 ° C and 210-250 ° F, the lubricant needs to be replaced once a month. If the oil temperature is above 120 ° C (250 ° F), the lubricant needs to be replaced once a week.
Proper installation and maintenance are important factors in the normal operation of KOYO bearings. At the same time, care must be taken to maintain the cleanliness of KOYO bearings. KOYO bearings must be protected from contaminants and moisture and must be properly installed and lubricated. In addition, KOYO bearing design, oil seal condition, lubricant form and replacement cycle and special maintenance also play an important role, and must be paid attention to.
