Advanced CNC Machined High Wear-Resistant C93500 Copper Bearing Bushing
Product introduction
Copper sleeve is a kind of bearing, which belongs to the large category of sliding bearing. It works under sliding friction. The relative shaft is rotating. Generally, it needs auxiliary lubrication system. The sliding bearing works stably, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear. The oil film also has certain vibration absorption capacity, which is used for lubrication, heat dissipation, friction reduction and life extension.
Copper sleeve is mainly used in machinery, printing and dyeing, papermaking, chemical industry, aerospace, coal, petroleum, automobile, engineering machinery, metallurgy and other industries.
The function of copper sleeve in the machine is to reduce friction, reduce vibration, prevent corrosion, reduce noise, easy to maintain and simplify structure manufacturing process. In moving parts, due to long-term friction will cause parts wear, at this time, the use of copper sleeve, can reduce friction. If the copper shaft sleeve is worn to a certain extent, it is only necessary to replace the copper shaft sleeve, so as to save the cost of replacing the shaft or seat.
