Proper application of imported bearings must pay attention to what problems the accessories of imported bearings are harmful to the accuracy, service life and characteristics of the bearing. Therefore, the design plan and assembly unit should conduct sufficient scientific research on the installation of imported bearings. During use, imported bearings should be frequently tested for basic external standards of operation, such as accurate measurements of temperature, vibration and noise. This regular inspection can detect potential difficulties as early as possible, avoid unexpected equipment interruptions, enable production plans to be completed, and improve the production processing and efficiency of processing plants. (1) Note that imported bearings with sealing can not be cleaned by this method, and the sealed interior should remain in the original state and cannot be cleaned. (2) The installation surface should be cleaned with a clean water solution such as gasoline, gasoline, xylene or xylene for vehicles, wiped with a clean towel, and then coated with a thin layer of smooth oil, so that the equipment can be practically operated. It is convenient and efficient. (3) When approaching the equipment, open the imported bearing bag, penetrate into the liquid such as gasoline for vehicles, and rotate briskly at the rhythm of the hand to ensure that the turning body and its raceway surface are completely clean and tidy. (4) When cleaning multiple bearings, use 90-100 ℃ hot motor oil to solidify the sealing oil, use a seamless interface and special tools that are difficult to burn for a few minutes to clean all the old oil, use gasoline to clean the motor oil, use gasoline and then use gasoline cleaning. After cleaning, put on film gloves and place the inlet bearing on a cleaning cloth or press on the bench.
