    A high-strength copper alloy brass bushing

    GRAPHITE SLEEVES

    GRAPHITE SLEEVES

    A high-strength copper alloy is used as the base material, and holes are machined in its working surface and filled with solid lubricant in a certain ratio according to the conditions of use. The high-strength copper alloy provides a high load-bearing capacity, while the solid lubricant creates a low friction. Under dry friction conditions we pre-design a lubricating film on the bearing surface to ensure that the solid lubricant is transferred to the coupling and an effective solid lubricant film is formed in the shortest possible time.
