The copper sleeve on the shaft acts as a bearing, which belongs to the category of sliding bearings. It is a bearing that works under sliding friction. It rotates relative to the shaft and generally needs to be assisted by a lubricating system. Shaft bushings work smoothly, reliably, and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear, and the oil film also has a certain ability to absorb vibration
The function is to lubricate, dissipate heat, reduce friction, prolong life, and so on.
Shaft bronze bushings are mainly used in machinery, printing and dyeing, papermaking, chemical industry, aerospace, coal, petroleum, automobile, construction machinery, metallurgy, and other industries.
