Starter Motor Bushing – XH003 (Size: 11×14.7×11mm, Copper-Graphite Composite)
Ensure superior durability and smooth operation for your starter motor with our Copper-Graphite Bushing (Model: XH003), engineered from high-performance copper alloy and graphite for optimal wear resistance and self-lubrication.
Technical Specifications:
• Precision Dimensions: 11mm (ID) × 14.7mm (OD) × 11mm (Length)
• Material Composition:
-
Copper alloy matrix (85% copper)
-
15% graphite impregnation
-
Oil-impregnated pores (5-10% porosity)
• Temperature Range: -30°C to +200°C
• Load Capacity: 60N/mm²
• Friction Coefficient: 0.08-0.12 (dry)
Key Features:
