The 390000 series spherical bearings are fixed with the inner ring of the bearing and the shaft, and the eccentric sleeve is fastened with a hexagonal screw. Maintenance, many people do not have the hand to disassemble and assemble bearings, so it is necessary to introduce the 390000 series spherical bearing disassembly and installation methods and precautions: disassembly

1. For the first time, use a hexagonal wrench to loosen the eccentric locking screw cover, and then insert a small rod into the top cover of the eccentric sleeve counterbore to counter rotate the rhythm of the eccentric shaft sleeve.

2. Unscrew the bearing bolts. Remove the bearings from the shaft and bearings. Please note that before splitting the house at one end of the axis. The other side of the shaft bearing bolt should be released to avoid damaging both ends of the bearing. install

1. Before installing the bearing on the shaft, you must first remove the fixed pin of the bearing cover and polish the surface of the shaft smooth, clean and remove oil to prevent rust and lubricate it on the magazine (allowing the bearing to rotate slightly on the shaft).

2. Install the bearing seat on the lubricating surface of the housing and mating bearings. Then assemble the bearing seat and bearing on the shaft. Push to the location you want to install.

3. Do not tighten the bolts to fix the bearing seat, as the bearing rotates to increase the internal energy of the bearing. It is also installed on the same shaft bearing and the seat on the other side, with the shaft several times to automatically locate the position of the bearing itself. Tighten the bearing seat bolts again.

4. With eccentric sleeve. The first condom is set eccentrically on the step in the bearing, and the rotation direction of the shaft is tightened by hand. Then insert a small iron fence or counter eccentric sleeve counterbore. Knock the rotation direction of the axis of the small bar with a hammer. Eccentric ring safety, and finally lock the hexagonal screw, eccentric sleeve.
