CNC machining bronze bearing sleeve
,custom copper alloy CNC parts
,precision 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
