KOBELCO SK350 Drive Sprocket Assembly/DPW manufacture high quality sprocket for heavy-duty excavator undercarriage parts.

Product Specifications

Key Manufacturing Features:

✔ High-Quality Material – Forged alloy steel (e.g., 42CrMo/SCM440) with heat treatment (quenching & tempering) for superior hardness (HRC 50-55) and impact resistance.
✔ Precision Machining – CNC-machined teeth profiles for exact fit with SK350 track chains, minimizing slippage and uneven wear.
✔ Advanced Welding Process – Robotically welded hubs/flanges for structural integrity under high torque loads.
✔ Sealed Bearing System – Lubricated, dust-proof bearings to extend service intervals in abrasive environments.
✔ Corrosion Protection – Shot-peened surface + epoxy coating or zinc plating for rust resistance.

Technical Specifications:

• Compatible Models: Designed for SK350 excavators (verify compatibility with SK350-5/SK350LC-8, etc.).

• Tooth Count: [e.g., 21 teeth] – Matches OEM sprocket pitch.

• Bolt Pattern: Standard flange mounting (provide dimensions if available).

• Weight: Approximately [80.5 kg/lbs] (varies by design).

Quality Assurance:

• Dimensional Accuracy: 100% inspected via CMM (Coordinate Measuring Machine).

• Load Testing: Simulated field conditions to exceed 10,000-hour service life.

• Certifications: ISO 9001, CE, or industry-specific standards .

Applications:

• Ideal for mining, construction, and demolition where high torque and abrasion resistance are critical.

• Replaces worn sprockets to prevent track derailment and undercarriage damage.
