When installing and assembling non-standard bearings, we have very strict requirements on the installation surface and location. If you do not pay attention to the impact of the assembly environment, foreign materials such as iron filings and burrs will be mixed into the non-standard bearings, which will cause noise and vibration during normal operation of the bearings, and may even damage the raceways and rolling elements. Therefore, when installing non-standard bearings, you must ensure that the installation surface and the environment are clean.
When lubricating non-standard bearings, it is not that the more grease is applied, the better. If there is too much grease in the bearing and in the bearing chamber, it will cause excessive stirring of the grease and produce extremely high temperatures. The best grease filling is best kept at one-half to one-third of the internal space of the bearing.
The bearing clearance should be selected according to the application conditions, not the smaller the radial clearance, the better. The radial clearance of non-standard bearings is basically divided into five categories: 2, 0, 3, 4, 5. Their clearance is arranged from small to large. Class 0 is the standard clearance type, used in conjunction with general operating conditions, normal temperature and commonly used interference fit. If the special working conditions of high temperature, high speed and low noise and low friction require a larger radial clearance. If higher accuracy is required, then it is more suitable to choose a smaller radial clearance. The separation type bearings do not have high requirements for clearance, because non-standard bearings need to withstand a certain load of rotation, and bearing coordination and load will produce a certain elastic deformation.
