How to check the roller bearing seat regularly

The regular inspection of the roller bearing seat is very important for the roller bearing manufacturer to keep the bearing seat in the best condition, and it can also reflect the problems found. Matters needing attention and related knowledge in the use of roller bearing seat. First of all, we want to emphasize that it is very important to keep the bearings lubricated and clean.

      When inspecting the roller bearing seat, clean the surface of the roller bearing seat, and then remove the parts around the bearing. We must pay attention to the fact that the oil seal is a very fragile part, so be extra careful when inspecting and disassembling, and do not exceed the applied force to avoid damage to the parts. Then carefully check the oil seals of the bearing seat of the bushing roller bearing and its surrounding parts. If there are any bad symptoms, they must be replaced. A bad oil seal will cause damage to the bearing, and the equipment should be stopped when used abnormally.

      Lubrication is very important, not only for roller bearings, but also for all bearings. But please note that it is not recommended to add too much grease to the bearing.

The inspection method for the lubricant of the roller bearing seat is:

 Touch a little bit of lubricating oil between the two fingers rubbing, if there are contaminants, you can feel it, or apply a thin layer of lubricant on the back of the hand, and then seal it for inspection. Then replace the lubricant of the roller bearing seat.

      The roller bearing seat, if possible, should be filled with fresh oil and let the machine rotate at low speed for a few minutes. Make the oil collect as much residual contaminants as possible, and then remove the oil.

      When replacing the grease in the grease-lubricated roller bearing housing, the separator used should avoid any part of the roller bearing housing with a cotton joint angle. Because these residual fibers may be sandwiched between the rolling parts and cause damage, especially in the application of small bushing bearings, this problem should cause more attention.

For users, it is necessary to understand the quality inspection of roller bearings and their commercial parts. For example, the material supply and quality management department] must check the quality of the purchased bearings. When there is a problem with the bearing components of the equipment, the equipment maintenance department often needs to check the bearing to determine whether the cause of the problem is the bearing itself or the application of the bearing.

At that time, the technical department often needs to know the specific values of various technical quality indicators of the bearing. Through analysis and calculation, determine the technical and quality indicators of the main engine using these bearings, or improve these indicators through technical means. For example, when judging the specific indicators that the designed main engine rotation accuracy may reach, it is often necessary to know the specific value of the bearing rotation accuracy. For example, in assembly technology, it is often necessary to know the error value and the direction of the maximum value between the shaft and the seat hole and the surface of the bearing assembly, and use the corresponding maximum value reverse installation method. In order to offset the error to the greatest extent, a relatively fertile spindle rotation accuracy can be obtained. In addition, in the assembly workshop, it is often necessary to measure the specific size of the bearing assembly surface, which is suitable for the actual size of the main machine journal and seat hole, so that the bearings of the same batch of main machines are more uniform, not too loose or too tight. In order to avoid the deformation of the revolving track or the creeping of the matching surface, it helps to ensure the rotation accuracy and working life of the spindle. In short, users must have the following knowledge: (1) What standards should be used for the inspection of bearing products; (2) What items should be inspected and why should be inspected; (3) What should be done before the quality inspection of bearing products, and why should be prepared; (4) What conditions should be used for each inspection item of bearing products? What methods and instruments should be used for inspection, and the inspection results must be within the acceptable tolerance range; (5) Bearing products are sometimes in large quantities and cannot be 100% tested , Which sampling plan should be used and how many quantities should be selected for inspection to reflect that all commercial bearings must be more comprehensive and reliable. The quality and inspection results are measured according to what standard to determine whether the goods are qualified or unqualified. Bearing acceptance can generally be divided into three categories, that is, routine inspection when the bearing arrives. Routine inspections check the dimensional accuracy, rotation accuracy, bearing clearance and residual magnetic strength of the bearings related to the assembly. Special inspection-check the vibration quality, noise quality and other special requirements of the bearing.
