Fuwa Camshaft Gasket: Specifications, Functions, Materials, and Applications
Key Specifications
• Thickness: Typically4mm ± 0.03mm(precision-machined for tight axial tolerances).
• Outer Diameter (OD):φ172mm(standard for thin-walled ring-type gaskets).
• Inner Diameter (ID):φ90mm(process-oriented ID for clamping during manufacturing).
• Parallelism:≤0.02mm(critical for flat-surface alignment and sealing integrity).
• Tolerances:
• Thickness:4mm ± 0.03mm(copper variants sensitive to thermal expansion).
• Groove depth:5mm ± 0.1mm(ensures proper lubrication channel dimensions).
Functional Roles
1. Axial Restraint & Positioning
• Prevents axial displacement of the camshaft, maintaining precise valve timing and engine efficiency.
• Critical in Fuwa trailer brake systems to sustain braking performance under load.
2. Sealing & Leak Mitigation
• Fills microscopic gaps between mating surfaces (cylinder head/block) to prevent combustion gas leaks and coolant/oil seepage.
3. Vibration Damping
• Absorbs mechanical vibrations, reducing noise and extending component lifespan.
4. Lubrication Distribution
• Features eccentric annular oil grooves (offset by 4mm) and radial slots to ensure uniform oil flow, minimizing friction and wear.
Material Composition
1. Copper Alloy
• Preferred for thermal conductivity and wear resistance in thin-walled designs.
• Requires precise machining to avoid deformation under load.
2. Quenched Alloy Steel
• Used in high-load applications (e.g., heavy-duty trucks) for enhanced hardness and fatigue resistance.
3. Composite Materials
• PTFE/graphite-based variants for self-lubricating properties in extreme temperatures or lubricant-starved environments.
Technical Parameters
• Surface Finish: ≤Ra 1.6μm (reduces friction and improves sealing).
• Hardness: HRC 40–45 (quenched steel variants).
• Operating Temperature Range: -40°C to +150°C (copper) / -30°C to +200°C (steel/composites).
Vehicle & Industrial Applications
1. Fuwa Trailer Brake Systems
• Ensures axial stability of camshafts in brake actuators, preventing misalignment and performance degradation.
2. Heavy-Duty Truck Engines
• Compatible with Fuwa 470/510/330 rear brake assemblies, maintaining valve timing accuracy under high RPM.
3. Industrial Machinery
• Used in high-torque engines and gearboxes requiring robust axial restraint and wear resistance.
Quality Assurance
• ISO 9001:2015 Certified Manufacturing
• 100% Dimensional Inspection(via CMM/optical measurement)
• Fatigue Testing(simulates 1 million+ cycles under load)
Key Considerations for Users
1. Model-Specific Fitment: Verify compatibility with Fuwa’s official part catalog (e.g., AZ4007443020 for right-side applications).
2. Installation Guidelines:
• Avoid over-tightening (recommended torque: 25–30 N·m for copper gaskets).
• Use thread-locking compounds sparingly to prevent gasket distortion.
3. Maintenance: Inspect for wear/corrosion every 50,000 km; replace if parallelism exceeds 0.03mm.
