Our factory’s graphite bronze bushes feature excellent self-lubricating performance, high wear resistance, good load-bearing capacity and low friction coefficient. With solid graphite plugs embedded in the bronze matrix, they can form a continuous lubricating film during operation without frequent oil or grease refilling. The composite structure reduces friction heat generation, resists seizure and adapts to intermittent or maintenance-difficult working conditions. Optimized material formulation delivers good dimensional stability and corrosion resistance, greatly extending service life. They are well suited for heavy load, low speed, oscillating motion and dry or boundary lubrication environments.These graphite bronze bushes are widely applied in construction machinery, hydraulic equipment, injection molding machines, mining machinery, agricultural machinery, lifting equipment, textile machinery and automotive auxiliary components, reliably satisfying the lubrication and wear-resistance demands of equipment where regular greasing is inconvenient.
