roduct Overview: OEM-Grade Undercarriage Components for Wirtgen
Our Wirtgen W1500 W1900 Milling Machine Track Chain Assembly with Polyurethane (PU) Pads is specifically made as a direct OEM replacement part for Wirtgen W1500 and W1900 cold milling machines. It is engineered for high-intensity asphalt milling and road rehabilitation. This track chain assembly, an essential component of Wirtgen road milling machine undercarriage parts, provides outstanding stability, excellent traction, and extraordinary wear resistance in challenging operating conditions.
Features
High-strength alloy forged track links, excellent load capacity and impact resistance
Wear-resistant PU track pads, anti-slip, resistant to moderate asphalt temperature
Detachable bolt design for easy maintenance and cost saving
Sealed lubricated hinge structure, resist sand and asphalt debris intrusion
Precise dimension to match W1500, W1900 milling machine undercarriage
Material & Manufacturing Process
B2B road construction contractors need undercarriage parts that can endure constant surface abrasion and high shear stress. High-durability polymers and sturdy steel alloys are used in the production of our track chains and pads:
| Component | Material / Specification | Heat Treatment & Craftsmanship |
| Track Links | 35CrMo / 40Mn2 Heavy Forged Alloy Steel | Deep induction hardening (HRC 52–58) to resist severe impact without fracturing. |
| Pins & Bushes | 20CrMnTi Premium Structural Steel | Carburized & quenched (Depth 2.5–3.0mm, HRC 58–62) with liquid-sealed lubrication to block asphalt dust. |
| Track Pads (PU/Rubber) | High-Density Wear-Resistant Polyurethane (PU) | Formulated with high tear-strength polyurethane bonded to heat-treated base plates to prevent delamination. |
Proven Working Hours & Field Performance Test Data
Our track chain assembly exhibits exceptional endurance based on thorough feedback and field data gathered from top road construction contractors throughout asphalt milling and highway maintenance projects:
Expected Service Life: Exceeds 3,500+ Working Hours in standard asphalt cold milling operations.
PU Pad Wear Rate: Reduced by 28% compared to conventional rubber pads under high-temperature asphalt conditions (up to 160°C).
Bonding Strength: Vulcanized base plate adhesion exceeds 15 N/mm, preventing pad detachment during sharp pivot turning.
Maintenance Savings: Quick-bolt detachable pad design reduces replacement downtime by 45% on-site.
Compatible Machinery (Direct Fit Replacement)
Wirtgen Cold Milling Machines: W1500, W1900, W1900DC, W2000 (standard track geometry).
Applications: Highway asphalt recycling, municipal pavement milling, concrete milling, and bridge deck preparation.
💡 Why Road Construction Contractors Choose Our Track Chain
100% Dimensional Compatibility: Precise pitch spacing seamlessly fits original Wirtgen driving sprockets and idler wheels.
Pavement Protection: High-friction PU track pads prevent surface scarring on newly laid asphalt during operation.
Sealed Lubricated Hinge Design: Retains internal grease while locking out abrasive asphalt fine particles, preventing early link elongation.
