The Importance Of Lubrication To The Operation Of FAG Bearings

Grease-lubricated bearings are best implemented during planned equipment downtime and are regularly replenished. At the same time, old grease is removed or used to squeeze out old grease. Wipe the grease nipple clean before adding fresh grease. If the bearing box does not have a grease nipple, the bearing box cover or end cover should be opened to remove the old grease, and after cleaning, add fresh grease of the same model.

Regularly check the oil level and quality of the lubricating oil. Under normal circumstances, the normal oil level should be within the range of 1 / 2-2 / 3 of the equipment oil level window or mark . The oil filling method is the oil cup. The oil level displayed only represents the oil filling capacity, and the oil level of the bearing box meets the operating requirements. The oil level in the oil cup is less than 1/4 of its total volume.

Inspection and replenishment methods, take a small amount of lubricating oil as a sample and compare it with fresh lubricating oil, capable units may consider conducting oil quality testing to ensure that the oil quality is qualified. If the sample looks cloudy, it may be the result of mixing with water, that is, the oil emulsification that everyone often says, and the lubricant should be replaced at this time. If the sample path becomes darker in color or thicker, 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 lubricating oil. When replacing the lubricant, make sure that the new and old models of the replaced lubricant 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 60-100 ° C (140-210 ° F), the lubricant needs to be changed four times a year. If the oil temperature is between 100-120 ° C (210-250 ° F), the lubricant needs to be changed once a month. If the oil temperature is above 120 ° C (250 ° F), the lubricant needs to be changed once a week.

Correct installation and maintenance are important factors for the normal operation of the FAG bearing. At the same time, care must be taken to maintain the cleanliness of the bearing. Bearings must be protected from contaminants and moisture, and must be properly installed and lubricated. In addition, the design of the bearing arrangement, the condition of the oil seal, the form of the lubricant and the replacement cycle and special maintenance also play an important role and must be paid attention to.
