Bearing periodic inspection of the impact of noise on the accuracy level

Regular inspections of bearings are important tasks to maintain the bearings in their best condition, and can also reflect the discovery of problems. Matters needing attention and related knowledge about bearings in use.
We want to emphasize that it is very important to keep the bearings lubricated and clean. So before we inspect the bearing, we should clean the surface of the bearing first, and then disassemble the parts around the bearing. Everyone should pay attention that the oil seal is a very fragile part, so you need to be extra careful when inspecting and disassembling. Do not apply excessive force to avoid damage to the parts. Then carefully check the oil seal of the bearing and its surrounding parts. If it shows bad symptoms, be sure to replace it. A bad oil seal will cause damage to the bearing and cause abnormal bearing cloudiness and cause the equipment to stop.
Secondly, we have to check the lubricant of the bearing. Lubrication is very important, but please note that too much grease should not be added to the bearing.
Dip a little bit of lubricant and rub between your fingers. If there are contaminants, you can feel it; or apply a thin layer of lubricant on the back of your hand, and then perform an optical inspection.
After using oil-lubricated bearings, after purging and removing the old oil, if possible, fill in fresh oil and let the machine rotate for a few minutes at a low speed. Try to collect the remaining contaminants in the oil as much as possible, and then remove the oil. Note: The oil should be filtered before use. When replacing the grease with grease-lubricated bearings, the cleaver should be used to avoid any part of the bearing with cotton material. Because these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings should pay more attention to this problem.
It’s better to use standard bearings when designing mechanical devices (this is to say whether the bearings are easy to purchase or not, here is a digression. Some bearing catalogues do have models, but some non-standard bearings are not available in mainland China, and some The futures will take a long time, so the time cost and the cost of later replacement should be considered when selecting the bearing. The load of the bearing and the load imposed on the bearing are changeable in nature, size and direction. Generally, the rated basic load is shown on the dimension table. However, axial load and radial load are also important factors in choosing a suitable bearing. When the size of the ball and needle roller bearings are the same, the bearings usually have a higher load capacity and can withstand greater vibration and shock loads.
