Description

     Self-lubricated bronze bearing guide bushing are manufactured with pre lubrication feature, designed to provide continuous lubrication during motion. The feature of pre lubrication eliminates the need for any further additional lubrication.
     Solid lubricant plugs is one type of common method for producing self-lubricating guide bushing, graphite is the best choice. The guide bushing are machined from cast bronze material, and then milled with multiple holes, which are then plugged with solid graphite plugs. Graphite plugs are inserted into the bronze bushing, and acts as a coating on both the mating shaft and the bushing surface, which provide the function of lubrication.
     This kind of bushing not only performs well in high temperature applications, but also applicable in locations that are difficult to service, because it has lots of advantages as below: total self-lubrication, excellent wear resistance, low coefficient of friction, wide operating temperature ranges, corrosion and chemical resistance, high precision with close tolerances, cost competitive...
