Maintenance of NSK 6205 bearings

Inspection and replenishment methods, take out a small amount of lubricating oil as a sample and compare it with fresh lubricating oil. Capable units may consider conducting an oil quality test to ensure that the oil quality is qualified. If the sample looks like a cloud, it may be the result of mixing with water, which is commonly referred to as oil emulsification, and the lubricant should be replaced at this time. If the sample path becomes darker or thicker, it may indicate that the lubricant has begun to be carbonized, and the old lubricant should be completely replaced. If possible, flush the oil circuit with fresh lubricant. When replacing the lubricating oil, make sure that the new and old models of the replaced lubricating oil are the same, and add the required oil level.

Use an oil bath type lubrication system. If the oil temperature is below 60°C (140°F) and the lubricating oil is not contaminated, the lubricating oil can be replaced 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 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 changed once a week.

Correct installation and maintenance are important factors for the normal operation of NSK bearings. At the same time, care must be taken to maintain the cleanliness of NSK 6205 bearings. NSK 6205 bearings must be protected from contaminants and moisture, and must be properly installed and lubricated. In addition, the design of the NSK 6205 bearing arrangement, the condition of the oil seal, the form of lubricant and the replacement cycle and special maintenance also play an important role and must be paid attention to.
