Product specifications: Guide bushing self-lubricating copper plus graphite guide bushing is A kind of high-strength brass with graphite or solid lubricant embedded on the basis of high-strength brass {(the main chemical composition percentages are: ~% .~.% .~.% .~.% .~.% ~% .)} Performance lubrication products. It breaks through the limitations of ordinary bearings relying on oil film lubrication. During use, frictional heat causes the solid lubricant to rub against the shaft, forming excellent conditions for oil and powder coexistence lubrication, which not only protects the shaft from wear but also makes the solid lubricating properties permanent. Its hardness is twice as high as that of ordinary copper sleeves and its wear resistance is twice as high.
