skf bearing installation steps

The installation of skf bearings is directly related to the use, life and performance of skf bearings. Therefore, when we use skf bearings, the first thing we need to master is the installation steps of skf bearings. China Bearing Network will tell you the relevant detailed knowledge based on our understanding.

skf bearing installation steps:

1. Before installing the skf bearing on the shaft, you must first unplug the fixed pin of the bearing jacket, and at the same time polish the surface of the journal smoothly and clean, and apply oil to the journal to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft) .

2. Apply lubricating oil on the mating surface of the skf bearing seat and the skf bearing, and put the skf bearing into the bearing seat. Then put the assembled skf bearing and skf bearing seat on the shaft together. Push to the desired location for installation.

3. Do not tighten the bolts that fix the skf bearing seat, and make the skf bearing housing rotate in the bearing seat. Also install the other end of the skf bearing and seat on the same shaft, rotate the shaft a few times, let the skf bearing itself automatically locate the position. Then tighten the bearing seat bolts.

4. Install eccentric sleeve. Put the eccentric sleeve on the eccentric step of the bearing inner sleeve first, and tighten it by hand in the direction of rotation of the shaft. Then insert the small iron rod into or against the counterbore on the eccentric sleeve. Knock the small iron rod along the axis of rotation with a hand hammer. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.

Reminder: if the skf bearing is installed upside down, not only the bearing will not work properly, but also the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not very obvious, special care should be taken during assembly to prevent reverse installation. When installed correctly, the seat ring should automatically adapt to the rolling of the rolling elements to ensure that the rolling elements are located in the upper and lower ring raceways. In addition, there should be a gap of 0.2-0.5mm between the seat ring of the skf bearing and the hole of the skf bearing seat to compensate for the errors caused by improper parts processing and installation. When the center of the bearing ring is shifted during operation , This gap can ensure its automatic adjustment, avoid touching and rubbing, and make it operate normally. Otherwise, it will cause severe damage to the skf bearing.
