Straight bush factory introduces little knowledge of making bushings

How much do you know about the production of bushings? The editor of Straight bush factory will show you a brief look!
The shaft sleeve is a part of the sliding bearing, which is a cylindrical mechanical part sleeved on the rotating shaft. Generally speaking, the shaft sleeve and the bearing seat adopt an interference fit, and the shaft sleeve and the shaft adopt a clearance fit. The difference between sliding bearings and ordinary bearings is that there are no rolling elements such as balls in the sliding bearings. Lubricating oil is usually injected to create an oil seal between the shaft and the sleeve, thereby reducing the wear between the shaft and the sleeve.


However, during use, it was found that when the shaft was rotating, the shaft sleeve and the bearing seat were installed, and the shaft sleeve was worn and corroded during use. A cermet bearing, which is provided with a ceramic layer outside the bearing and uses the corrosion resistance and wear resistance of the ceramic to improve the corrosion resistance and wear resistance of the shaft sleeve. However, this setting method is only suitable for small shafts. However, the general large-scale shaft sleeve is usually processed by split processing. The method of setting the ceramic layer on the small shaft sleeve is not suitable for large bearings. During the use of the shaft sleeve, once the split shaft sleeve moves, This will cause the ceramic layer to break between the split sleeves.
In summary, the editor of Straight bush factory introduced the little knowledge of making bushings.
