SY750RC-LD700RC Forging Bucket Tooth/Heavy-Duty Excavator Teeth OEM Quality/original factory supply directly.

Product Specifications

The SANY LD700RC Forging Bucket Tooth is a critical wear part designed specifically for SANY LD700RC excavator buckets. These teeth are manufactured through precision forging for superior strength and impact resistance in demanding applications.

2. Key Features & Advantages

① Forging Technology Superiority

• Enhanced Durability: Hot-forging process aligns grain structure, achieving 30-40% higher impact resistance compared to cast teeth.

• Optimal Density: Eliminates porosity defects common in casting, reducing crack propagation risks.

• Precision-Formed Geometry: CNC-machined to match OEM tooth profile (SAE J1175 standard).

② Material Science

• Alloy Composition:

  • Base Material:  high-tensile alloy steel

  • Hardness: 48-52 HRC (Rockwell C scale) core hardness with 55-58 HRC flame-hardened tip

  • Impact Toughness: ≥45 J/cm² at -20°C (ASTM E23)

• Surface Treatment:

  • Shot peening for stress relief

  • Anti-corrosion coating (zinc-phosphate) for humid environments

③ Compatibility & Mounting

• Adapter System: H-style locking mechanism (per ISO 9001 excavator tooth standards)

• Installation Torque: 450-500 N·m for lock pins (use calibrated torque wrench)

• Weight: 33.6 kg ±2% (per single tooth)

7. Maintenance Protocol

1. Pre-Installation

   • Degrease adapter pockets with solvent

   • Apply molybdenum disulfide paste to lock pin grooves

2. Operational Checks

   • Inspect every 50 service hours for:

     • Tooth retention force (should resist 5-ton lateral load)

     • Symmetrical wear patterns

3. End-of-Life Criteria

   • Replace when:

     • Tip wear exceeds 60% of original length

     • Any visible cracks in stress zones

8. FAQs

Q: Can these teeth be rebuilt via hardfacing?
A: Not recommended – Hardfacing alters metallurgical properties and voids warranty.

Q: Alternative for wet clay conditions?
A: Consider parabolic-shaped teeth (reduces material sticking).

Q: Export packaging details?
A: Standard export wooden crate (20 teeth/crate, gross weight 210kg).
