Undercarriage Parts/Track Rollers

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized track roller components within our undercarriage parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and roller configurations, ensuring that every component meets rigorous Komatsu standards for load performance and preventive maintenance:
• Machine & Heavy-Duty Track Roller System Compatibility: Engineered for a broad range of Komatsu excavators and bulldozers, our roller solutions ensure exact material strength ratings, dimensional tolerances, and structural interface definitions for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty Track Roller Range: 1. Single & Double Flange Rollers: Designed to withstand hundreds of tons of vertical static loads and side thrusts, featuring deep-hardened wear-resistant rail surfaces; 2. Maintenance-Free Roller Assemblies: Integrated units combining high-precision duo-cone floating seals and high-quality wear-resistant bearings for extended travel support; 3. Heavy-Duty Roller Shells & Shafts: Replacement internal components built for extreme jobsite durability.
• OEM & Aftermarket Options: Certified original equipment manufacturer Komatsu track roller parts alongside high-performance aftermarket alternatives featuring reinforced wear-resistant alloy formulas, delivering operational reliability and extended service lifespan at a cost-effective procurement point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global track roller component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of thousands of single and double flange track rollers matching Komatsu mainstream excavators and bulldozers. Backed by barcode-enabled intelligent warehousing and Komatsu cross-reference databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replenishment needs for overseas fleet workshops and minimize equipment downtime caused by roller bearing seizure halting complete machine operations.
• Anti-Rust Coating and Port Protection: We implement specialized industrial packaging standards for the roller track surfaces, mounting flanges, and oil filling ports of all track rollers utilizing heavy-duty long-lasting anti-rust agents and thick-walled industrial moisture-proof wrapping film for tight individual wrapping to ensure absolute freedom from metal oxidation under transcontinental ocean freight salt spray and high humidity environments.
• Heavy-Duty Palletization and Steel Strapping: Bulk heavy-duty track roller shipments are packed neatly on high-strength export fumigated wooden pallets, locked securely with multiple strands of high-strength cross-applied steel strapping on the perimeter, and fastened robustly to wooden pallet bases through bolts to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without package splitting.
• Consolidated Sourcing for Undercarriage Overhaul Kits: We support overseas clients by consolidating large track roller assemblies alongside matching full sets of track chain assemblies, sprocket rims, and idlers into precise bundled undercarriage maintenance kits, achieving a one-stop purchasing model that pairs heavy load components with chassis service supplies while significantly reducing comprehensive logistics costs for overseas workshops.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for asset health monitoring reliability.
• Application-Specific Track Roller Durability Solutions: We address extreme jobsite challenges—such as granite crushed stone and abrasive open-pit iron mines—where original track rollers suffer local rim flaking or early bearing wear. We also provide professional engineering upgrades utilizing high-purity boron alloy cast steel treated through deep induction hardening, paired with specialized wear-resistant floating seals.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like harsh undercarriage metal friction, shell overheating, or roller seizure. This focuses on two critical protocols: 1. Shift-End Cleaning & Anti-Locking: Technicians must wash away stones and sticky mud from undercarriage frames after every work shift; strictly prohibit mud caking from locking rollers and causing track links to grind flat spots onto roller surfaces; 2. Symmetric Group Replacement: When single-side rollers suffer severe wear during overhauls, they must be replaced in symmetric groups; strictly prohibit mixing new and old rollers, as height variations cause localized overloading and uneven link wear.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including track roller disassembly diagrams, frame mounting face cleaning norms, torque wrench tightening standards, and visual guides, assisting overseas technical personnel in executing standardized construction.
