Commonly used rolling bearing specifications
Rolling bearings are generally more resistant to wear under normal conditions, but improper assembly, inadequate sealing, insufficient lubrication or impure grease, and foreign matter entering the bearing can cause premature wear of the rolling bearing. In addition, the bearing will wear when the journal and the inner ring of the bearing, the end cap hole and the bearing outer ring are swung. The degree of wear of the bearing is determined by the clearance. If the clearance exceeds the maximum allowable wear specified in Table 1.3, the new bearing should be replaced.
When the bearing and the end cap hole are loosened, a chisel can be used to make a row of stamps on the circumference of the end cap bearing chamber to clamp the bearing outer ring for emergency use.
If there is rust on the processing surface, it can be cleaned with gasoline cloth No. 00 and then put in gasoline.
When the bearing is damaged, several bearings of the same type can be disassembled, and the selected ones can be assembled into one bearing. Only bearings that are damaged by balls or balls can be replaced, and only balls can be replaced without having to replace the bearings.
In addition, when the rolling bearing of the high speed motor is not worn seriously, it can be used on a low speed motor.
