In some special places, it is equivalent to the role of bearing, such as heavy load, low speed, and large impact of mechanical load. When the smoothness is outstanding, the service life is also long. The copper sleeve on the shaft plays a bearing role, also known as sliding bearing. It is a bearing operating under sliding collision, and the relative shaft is rolling. Generally, it needs to assist with smooth system operation or self smooth bearing.
The operation of sliding bearing is stable, reliable and noise free. Under the condition of smooth liquid, the sliding surface is separated by smooth oil without direct contact, which can greatly reduce the friction loss and surface wear, and the oil film has certain vibration absorption ability.
Graphite copper sleeve
Graphite copper sleeve is mainly based on high strength copper alloy (also known as JDB solid inlaid self smooth bearing). What are the characteristics of graphite copper sleeve?
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and self smoothness, which is especially suitable for heavy load, low speed, reciprocating or shaking occasions which are difficult to smooth and form oil film.
Because of its high hardness and strength, and low cost, its service life is twice higher than that of common copper sleeve in low speed and heavy load situation, so it is favored by customers. Different sizes and materials can be customized according to customer requirements.
