1. Loosen the bolts that secure the bearing block. Remove the fag dealer imported bearing from the shaft together with the bearing seat. Note before removing the fag dealer bearing housing at one end of the shaft. The I-bearing bolt at the other end of the shaft should be loosened to avoid damage to the bearings at both ends.

2. First use an Allen wrench to loosen the locking screw on the bearing eccentric sleeve of the fag dealer, and then use a small iron rod to insert the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the direction of shaft rotation.

Many people use improper installation methods in the installation of bearings, resulting in damage to the bearings provided by fag dealers. So how to install bearings correctly? I hope that you will have a more comprehensive understanding of bearing installation and disassembly:fag dealer

For clearance-fitting bearing rings, it is recommended to apply a thin layer of anti-creeping corrosion agent on the mating surfaces to prevent friction corrosion between the mating surfaces.

The 390000 series outer spherical bearing is used to fix the inner ring of the bearing and the shaft through an eccentric sleeve, and the hexagonal screws on the eccentric sleeve are used for fastening. During maintenance, many novices will not disassemble the bearings of this fag dealer, so it is necessary to introduce the technical points and precautions of disassembling and mounting 390000 series spherical bearings:

Correct installation is very important for the use of fag dealer bearings. I hope you can use the correct installation method in future use.

During installation, you can choose mechanical, heating or hydraulic methods according to its type and size. The force applied to the bearing during installation must never be transmitted from one bearing ring to the bearing ring provided by another fag dealer through the rolling elements, otherwise the raceway may be damaged. However, under no circumstances should the bearing rings, cages, rolling elements or seals be struck directly.fag ball bearing

1. Install an eccentric sleeve. First put the eccentric sleeve on the eccentric step of the bearing inner sleeve of the fag dealer, and tighten it by hand in the direction of shaft rotation. Then insert the small iron rod or press against the counterbore on the eccentric sleeve. Use the hammer to tap the small iron rod in the rotation direction of the shaft. Make the eccentric sleeve securely installed, and finally tighten the hex screw on the eccentric sleeve.

2. Do not tighten the bolts of the bearing housing of the fag dealer first, but make the bearing jacket rotate in the bearing housing. Then tighten the bearing seat bolts. Also install the other bearing and seat on the same shaft, rotate the shaft a few times, and let the German FAG bearing provided by the fag dealer automatically correct the position.

3.Lubricate the bearing seat and bearing mating surface, and install the bearing of the fag dealer into the bearing seat. Then put the assembled bearing on the shaft together with the bearing housing of the fag dealer. Push to the required position for installation.

4.Before installing the fag dealer bearing on the shaft, you must first remove the fixing pin of the bearing jacket, and at the same time, polish the surface of the journal to smooth and clean, and apply oil to the shaft to prevent rust and lubrication (allowing the bearing to rotate slightly on the shaft).
