Excavator drive sprocket for Doosan DX500 undercarriage

Excavator drive sprocket for Doosan DX500 Technical Specifications

The "Chain Reaction" of Wear

The drive sprocket (final drive sprocket or track drive wheel) is the powered component in an excavator's undercarriage that engages the track chain to deliver torque and propulsion from the final drive motors. For heavy-duty machines like the Doosan DX500, a durable sprocket ensures reliable traction, efficient power transfer, and minimal slippage on demanding job sites involving quarrying, mining, large-scale earthmoving, or demolition.

In the undercarriage world, parts wear out together. Here is how one bad part affects the sprocket:

Product Advantages

• Extreme Durability – Hardened teeth withstand high-impact rocks, gravel, and constant heavy loads, extending sprocket and track chain life significantly.
• Reliable Power Transfer – Precise tooth design prevents chain slip, maximizes hydraulic efficiency, and reduces strain on final drives.
• Direct Replacement Fit – Bolt-on compatibility with Doosan DX500 final drive – no modifications required, quick install.
• Cost & Uptime Savings – Minimizes downtime from sprocket failure, protects rollers, idlers, and chains from accelerated wear.
• Heavy-Duty Performance – Ideal for 45–55 ton class excavators in mining, quarrying, and large infrastructure projects.

Each DX500 typically uses one sprocket per side (2 total per machine) – replace in pairs for balanced operation.
