• Material and process: Made from copper powder or copper alloy powder, it is molded, sintered at high temperature, and further processed to combine the electrical conductivity and thermal conductivity of copper with the porosity characteristics of powder metallurgy.
• Self-lubricating properties: After sintering, a porous structure is formed inside, which can be impregnated with lubricating oil. During operation, friction heat causes the oil to seep out and lubricate the parts, making it suitable for mechanical parts that are difficult to maintain regularly.
• Wear and corrosion resistance: Copper base combined with alloy elements to enhance wear resistance and corrosion resistance, enabling long-term stable operation in humid and dusty environments.
• Precision and adaptability: Precision machining can control dimensional tolerances to adapt to different shaft diameters, and installation is simple, reducing equipment assembly time and costs.
• Wide range of applications: Commonly used in textile machinery, printing equipment, hydraulic systems, etc., especially suitable for low-speed, heavy-load conditions where frequent lubrication is inconvenient.
