Precision CNC Machining China Bronze Bearing Sleeve Custom Copper Alloy Parts CNC Machining Services

The bronze bearing sleeve is a sliding bearing component manufactured from high-density copper alloy through precision CNC machining, utilizing CuSn6.5P0.1 or CuSn8P0.3 bronze as base material. The product surface features regularly arranged diamond-shaped oil pockets that quickly form an oil film during initial operation, reducing friction coefficient. Suitable for medium-load and low-speed conditions, it offers excellent wear resistance and long service life, widely applied in various mechanical sliding parts.

• High Load Capacity: Static load capacity up to 120N/mm², dynamic load 40N/mm², hardness HB 90-120
• Excellent Wear Resistance: Friction coefficient 0.08-0.25, PV value 2.8N/mm²·m/s, extends equipment service life
• Optimized Lubrication Design: Surface diamond oil pockets store grease, enabling minimal lubrication suitable for hard-to-lubricate conditions
• Wide Temperature Adaptability: Operating temperature range -100℃~+200℃, meets various environmental requirements
• Thin-Wall Lightweight Structure: Light weight and compact size helps reduce mechanical structure dimensions
• Good Thermal Conductivity: Thermal conductivity 60W/(m·K), linear expansion coefficient 15*10⁻⁶/K, ensures stable operation

• Industrial Machinery: Sliding parts of automated machinery (extension, swing, sliding), hydraulic cylinder guide sleeves
• Transportation Equipment: Automobile, tractor, truck chassis components, motorcycle industry
• Specialized Machinery: Textile machinery, plastic molding machines, die-casting machines, rubber machinery
• Engineering Machinery: Port equipment, water conservancy engineering machinery, agricultural machinery, mining equipment
• Power Transmission Equipment: Conveyors, elevators, winches, leveling machines

We provide comprehensive customization services, offering precision machining based on customer drawings or samples. Non-standard size customization is supported with tolerance ranges up to housing hole H7, bearing f7 or h8 grades. Custom surface oil pattern designs (diamond or hemispherical), lubrication methods (grease or solid self-lubrication) and special structural forms (straight sleeves, flanged bushings, thrust washers, etc.) are available. Material formulations can be adjusted according to special working conditions to meet corrosion resistance, high temperature and other specific requirements.

• Technical Consultation: Product selection, installation guidance and fault diagnosis services
• Quality Assurance: Strict quality control system ensures stable product performance
• After-sales Service: Customer with regular follow-ups and maintenance recommendations
• Logistics Support: Flexible delivery scheduling to ensure project timeline requirements
