Oil-free sliding bearing works smoothly, reliably and noiselessly. In addition, the oil film also has a certain ability to absorb vibration. Then how to maintain and install the oil-free sliding bearing? The following and Hangzhou self – lubricating bearing xiaobian together to understand it.

Hangzhou self-lubricated bearing

The main technical requirement of the oil-free sliding bearing assembly is to maintain a reasonable clearance between the journal and the bearing to ensure good contact between the journal and the bearing and adequate lubrication of the copper sleeve so that the journal can rotate and maintain a smooth rotation and is installed reliably in the bearing.

Installation of oil-free sliding bearing assembly:

(1) Before assembly, deburring the shaft sleeve and bearing seat hole, clean dry and oil-free bearings, and apply lubricant to the bearing seat hole.

(2) According to the size of the shaft sleeve and the amount of interference in the installation process, install the shaft into the hole of the bearing seat and fix it by percussion or extrusion.

(3) After pressing the sleeve into the bearing hole, the size and shape may change. The inner bore of self-lubricated bearings should be trimmed and checked by reaming or scraping to ensure a good relationship between journal and sleeve. The gap is appropriate.

Maintenance of oil-free sliding bearing:

(1) The maintenance of integral sliding bearing generally adopts the method of replacing the bushing.

(2) The split sliding bearing is slightly worn, which can be solved by adjusting the gasket and scraping again.

(3) If the working face is not seriously scratched, only precision dressing is needed, then the clearance can be adjusted with a nut; When the working surface is badly scratched, the spindle should be removed and the bearing scraped again to restore its matching accuracy.
