German FAG bearing disassembly and assembly skills maintenance method

1. Loosen the bolts that secure the bearing housing. The German FAG bearings are removed from the shaft together with the housing. Note before the German FAG housing on the end of the shaft. The I-bearing bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being damaged by each other.

2. First loosen the locking screw on the eccentric sleeve of the German FAG bearing with an Allen key, then insert the small iron rod into the counterbore on the eccentric sleeve of the top cover and loosen the eccentric sleeve against the direction of rotation of the shaft.

Many people use improper installation methods in the installation of bearings, resulting in damage to German FAG bearings. So how do you install the bearings correctly? I hope everyone can understand the installation and disassembly of the bearing more comprehensively:

For clearance-fitted bearing rings, it is recommended to apply a thin layer of anti-creeping etchant on the mating surface to prevent frictional 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 hexagon socket screw on the eccentric sleeve is used for fastening. In the maintenance, many operators will not disassemble this German FAG bearing, so it is necessary to introduce the technical points and precautions for disassembling the 390000 series outer spherical bearing:

Proper installation is very important for the use of German FAG bearings. I hope that everyone can use the correct installation method in future use.

When installing, it can be selected according to its type and size, mechanical, heating or hydraulic. The force applied to the bearing during installation must never be transferred from one bearing ring to another German FAG bearing ring by rolling elements, otherwise the raceway may be damaged. However, under no circumstances can you directly hit the bearing ring, cage, rolling element or seal.

installation

3. Install the eccentric sleeve. Firstly, the eccentric bushing is placed on the eccentric step of the German FAG bearing inner sleeve, and the hand is screwed in the direction of the shaft. Then insert or hold the small iron rod against the counterbore on the eccentric sleeve. 1. Use a hammer to strike a small iron rod in the direction of rotation of the shaft. Install the eccentric sleeve securely and finally lock the socket head cap screws on the eccentric sleeve.

4. The bolts that fix the German FAG bearing housing should not be tightened first, so that the bearing housing can rotate in the bearing housing. Then fasten the bearing block bolts. Also install the other end bearing and seat on the same shaft, rotate the shaft a few turns, and let the German FAG bearing itself automatically find the position.

5. Apply lubricant to the bearing seat and bearing mating surface, and install the German FAG bearing into the bearing housing. Then the assembled bearing is placed on the shaft together with the German FAG bearing. Push to the desired location for installation.https://www.supplyforever.com/
