What is Bush? What do you mean by scraping the Bush? How to operate?
1., rolling bearings are easy to use and maintain, reliable work, good starting performance, high bearing capacity at medium speed. Compared with plain bearings, rolling bearings have larger radial sizes, less vibration damping capacity, low speed and low noise.2., the part of the shaft supported by the bearing is called the journal, and the part matching the journal is called the bush. It is made up of a whole cylindrical Bush called a bushing
The difference between sliding and rolling bearings is that the former journal and bearing surface work to form sliding friction, while the latter mainly form rolling friction.
