- Jun 27, 2018-

Before removing the miniature spherical bearing for inspection, make a record of its appearance. At the same time, confirm the amount of residual lubricant and sample the lubricant before cleaning the miniature spherical bearing. At the time of inspection, it mainly checks its standard accuracy, rotation accuracy, internal clearance and cooperation surface, raceway surface, holding frame and sealing ring.


As for the inspection results, it is generally required to determine the application requirements, the degree of importance, and the inspection period of the miniature spherical bearing. Replace it if necessary. When installing, it is necessary to remove the fixing pin of the bearing outer jacket, and at the same time, smooth the surface of the journal surface and apply grease to the journal to prevent rust and lubrication.


It is usually required to apply proper amount of lubricating oil on the bearing surface of the bearing seat and the miniature spherical bearing, punch the outer spherical bearing, and put the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location for installation. The bolts securing the bearing housing should not be tightened first, but the miniature spherical bearing housing can be rotated within the bearing housing. Make the eccentric sleeve securely, and finally lock the hexagon socket screw on the eccentric sleeve.
