The composite material used in the self-lubricating bearing of graphite graphite bushing is a new kind of extreme pressure resistant solid lubricant material, which consists of a metal substrate and a solid lubricant paste embedded in the hole or groove of the substrate. The metal substrate bears most of the load during the friction process. Through friction, the solid lubricant in the hole or groove transfers or reversely transfers to the friction surface, and a solid transfer film with good lubrication, firm adhesion and uniform coverage is formed on the friction surface, and friction and wear are greatly reduced. With the progress of friction, the embedded solid lubricant is continuously provided on the friction surface, ensuring good lubrication of the friction pair during long-term operation.

Inlaid graphite copper sleeve

Centrifugal Casting → Rough Turning → Inlaid Graphite Grain → Finishing → Finished Packing

Each procedure has strict inspection standards, and the production orders go from the casting to the finished product all the way to the end to ensure the planning standards and production time control.
