The main bearing is the contact part between the sliding bearing and the shaft. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloys. In special cases, it can be made of wood, plastic or rubber. Also called "bushing", the shape is a tile-like semi-cylindrical surface.
Moving characteristics
When the sliding bearing is working, a thin oil film is required between the bearing bush and the rotating shaft to lubricate. If there is direct friction between the bearing bush and the rotating shaft due to poor lubrication, the friction will generate a very high temperature. Although the bearing bush is made of special high temperature resistant alloy material, the high temperature generated by direct friction is still enough to burn it. Bad. The bearing bush may also burn due to factors such as excessive load, high temperature, impurities in the lubricating oil or abnormal viscosity. The sliding bearing is damaged after burning the tile.Product Parameter
