Precautions before installing the bearing

First of all, we need to understand some of the installation precautions that we need to know before installing the bearings. This is very helpful for us to install the bearings:

1. Whether the dimensions of the shaft and the bearing body are machined according to the requirements of the drawings, whether the corners of the bearing body and the right angle parts are convex, whether it can be completely in contact with the end surface of the bearing, sufficient inspection is required.

2. It should be determined whether there are any injuries or protrusions on the mating surfaces of the shaft and the bearing body. Whether dust or mold sand is attached to the surface of the bearing shell. If it is necessary to remove it with oil grindstone, fine sandpaper or a clean rag.

3. In order to avoid bumps during installation, a small amount of lubricating oil should be applied to the working surface of the shaft and bearing body.

3. Installation of the bearing - Method of applying force and force The bearing must be applied to the inner ring when it is mounted on the shaft. When it is mounted on the bearing body, it must be applied in the outer ring. Note: The bearing is mounted on the shaft. Do not tap the outer ring. When installing on the bearing body, do not hit the inner ring. If such operation occurs, the bearing track surface will be scratched, which will cause noise and early peeling damage, which will affect the bearing life. When applying force on the bearing, be careful to make the force vertical and even down. The partial stroke will cause the bearing to be injured. To this end, absolutely try to avoid partial hits. In addition, it is not possible to apply force to the cage of the bearing and the sealing plate.

4, the installation of the bearing - the installation of the hammer and the casing using the hammer and casing installation method, is a commonly used method, be sure to make the sleeve in the middle and knock it in, as shown in the figure, the hammer should be tapped gently .

5. Installation of the bearing - When the inner and outer rings are installed at the same time, the inner and outer rings are tightly matched. When the inner and outer rings are tightly fitted, the pad should be used. It is necessary to force the inner and outer rings to be knocked in at the same time. If only an external force is applied to the inner ring, the force will be pressed into the outer ring by the ball, and therefore, the track will be scratched.
