Undercarriage Parts/Rubber Tracks

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized rubber track components within our undercarriage parts catalog to support diverse compact equipment. Our product lineup covers a broad range of machine series and track configurations, ensuring that every component meets rigorous Komatsu standards for undercarriage performance and preventive maintenance:
• Machine & Heavy-Duty Rubber Track System Compatibility: Engineered for a broad range of Komatsu mini and compact excavators and loaders, our rubber track 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 Rubber Track Range: 1. Continuous Steel Cord Tracks: Built via jointless single-piece molding with high-strength multi-strand spiral-wound steel cords providing exceptional tensile strength; 2. Multi-Functional Tread Patterns: Including standard multi-purpose treads (balancing mud traction and hard-surface travel) and heavy-duty construction treads (thickened cut-resistant designs for crushed stone environments); 3. OEM & Aftermarket Options: Certified original equipment manufacturer Komatsu tracks and high-performance aftermarket alternatives featuring tear-resistant reinforced natural rubber formulations.
• Procurement Value: These solutions deliver operational reliability and extended service lifespan while providing flexible, cost-effective procurement options for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global rubber track component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and rental fleets.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of hundreds of rubber tracks across all specifications matching Komatsu mainstream mini and compact excavators. 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 clients and minimize equipment downtime caused by track breakage halting complete machine operations.
• Anti-Aging Sealing and Anti-Deformation Packaging: We implement specialized industrial packaging standards for the rubber surfaces of all rubber tracks utilizing anti-UV aging agents and thick-walled light-shielding moisture-proof plastic sealing film for independent multi-layer tight wrapping, while utilizing custom high-strength internal support struts to maintain circular profiles and ensure physical properties remain stable and free from flattening or permanent ring deformation under transcontinental ocean freight and warehouse storage environments.
• Heavy-Duty Palletization and Steel Strapping: Bulk heavy-duty rubber track shipments are stacked flat neatly on high-strength export fumigated wooden pallets and locked securely with multiple strands of high-strength cross-applied steel strapping on the perimeter to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without package splitting.
• Consolidated Sourcing for Rubber Track Undercarriage Kits: We support overseas clients by consolidating large rubber track sets alongside matching full sets of bottom track rollers, top carrier rollers, front idlers, and drive sprocket rims into precise bundled rubber track undercarriage maintenance kits, achieving a one-stop purchasing model that pairs compact equipment 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 Rubber Track Durability Solutions: We address extreme jobsite challenges—such as abrasive stone yards and demolition sites—where original tracks suffer rubber block chipping or outer steel cord exposure under sharp rock compression. We also provide professional engineering upgrades utilizing high-wear tear-resistant natural rubber formulations, high-density jointless spiral-wound high-carbon steel cords, and exceptional puncture resistance.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like sudden track detachment, sprocket interference noises, or rapid elongation. This focuses on two critical protocols: 1. Track Sag & Tensioning: Technicians must regularly check track sag according to Komatsu manuals, maintaining a strict clearance of 10-15 mm to prevent loose tension from causing derailment or excessive tightness from over-stressing internal steel cords; 2. Debris Clearing & Turn Restrictions: Operators must immediately clear embedded stones between iron lugs after operations and strictly avoid high-speed in-place 360° pivot turns on hard surfaces.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including mini excavator track disassembly diagrams, grease tensioner pressure relief/filling specs, idler retraction standards, and visual guides, assisting overseas technical personnel in executing standardized construction.
