Graphite copper bushings (also called solid lubricated bearings) are a key type of sliding bearing.
This bushing innovatively drills holes in high-strength brass sleeves and embeds solid graphite as lubricant, perfectly combining brass's high load capacity, wear resistance with graphite's low friction and self-lubricating properties. It operates smoothly even without oil, it has lower friction, less wear, and longer service life.
Product Features：
Material Advantages: High-strength brass is hard, corrosion-resistant, and withstands high temperatures and coastal humid climates; evenly embedded graphite particles enhance lubrication stability and reduce shaft wear.
Precision Design:With tight tolerance, fits shafts closely during installation, avoiding shaking; oil-free design eliminates frequent oiling, reduces maintenance costs, and suits automated equipment or hidden parts.
Advantage：
Traditional bearings easily rust or seize in high-temperature, humid environments, or wear rapidly due to oil shortage. This bushing, with brass corrosion resistance and graphite self-lubrication，whether for high-speed machine tools or humid washing machines, it maintains stable performance and reduces equipment failures.
