628 zz bearing temperature overheat solution
Because of the different causes of heating of the 628 zz bearing, the solutions are also different. The following is the solution when the temperature of the 628 zz bearing is overheated:
1, the fat filling method, the so-called fat filling method is regularly to the bearing working surface to fill the appropriate amount of grease, is one of the most commonly used grease lubrication.628 zz
2. Oil cup method: The oil cup method is to set a cap-type oil cup or pressure oil cup on the bearing seat, and regularly rotate the cap or oil gun to inject grease.This is also a common form of grease lubrication.
3, pressure grease method, pressure grease method is dependent on grease pump grease.At this point should choose a good flow of grease.
4, centralized grease supply method, centralized grease through the grease pump, at the same time to each 628 zz bearing and other parts of the grease.Similarly, the grease should be of good flow resistance, oxidation resistance and corrosion resistance, which is also a pressure grease.
