Undercarriage Parts/Rubber Protectors

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized rubber protector components within our undercarriage parts catalog to support diverse crawler equipment. Our product lineup covers a broad range of machine series and rubber pad configurations, ensuring that every component meets rigorous Komatsu standards for surface protection and preventive maintenance:
• Machine & Heavy-Duty Rubber Protector System Compatibility: Engineered for a broad range of Komatsu excavators, our rubber protector 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 Protector Range: 1. Bolt-On Rubber Pads: Fixed directly to metal track shoes through high-strength bolts for primary surface protection during frequent concrete and asphalt road operations; 2. Clip-On & Chain-Attached Protectors: Designed for rapid snap-on removal without bolt disassembly to adapt to temporary jobsite transfers and municipal emergency repairs; 3. High-Tensile Rubber Pad Hardware: Utilizing special anti-loosening coatings with exceptional tensile and vibration-shedding resistance.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu rubber protector parts alongside high-performance aftermarket alternatives featuring tear-resistant reinforced rubber formulations, 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 rubber protector component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and municipal contractors.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of thousands of bolt-on rubber pads in various dimensions and dedicated bolts matching Komatsu mainstream 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 road protection damage resulting in municipal fines or stoppages.
• Anti-Aging Sealing and Heavy-Duty Palletization: We implement specialized industrial packaging standards for the rubber surfaces of all rubber protectors utilizing anti-UV aging protective agents and thick-walled moisture-proof light-shielding plastic film for independent multi-layer tight sealing, eliminating rubber adhesion or accelerated aging during hot seasons to ensure physical properties remain stable under transcontinental ocean freight and warehouse storage environments.
• Heavy-Duty Palletization and Edge Protection: Bulk heavy-duty rubber protector shipments are packed neatly on high-strength export fumigated wooden pallets, locked securely with multiple strands of high-strength cross-applied steel strapping, and reinforced with L-shaped corner guards on the perimeter to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without package splitting or deformation.
• Consolidated Sourcing for Undercarriage and Protection Kits: We support overseas clients by consolidating large rubber protector sets alongside matching full sets of Grade 10.9 dedicated fixing bolts, track rollers, and track chains into precise bundled protection maintenance kits, achieving a one-stop purchasing model that pairs surface protection 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 Protector Durability Solutions: We address extreme jobsite challenges—such as high-density urban asphalt roads and frequent in-place 360° turns—where original rubber pads suffer surface tearing or internal steel-rubber debonding under high shear forces. We also provide professional engineering upgrades utilizing tear-resistant natural rubber formulations, internal steel skeletons treated with special chemical adhesive strong vulcanization, and exceptional shear fatigue strength.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like rubber pad ejection, collective bolt fracture, or loosening during urban construction. This focuses on two critical protocols: 1. Torque & Steering Protocols: Technicians must use torque wrenches to re-tighten all fixing bolts before commissioning and after the initial 50 operating hours (preventing settlement shear), while operators must avoid sharp in-place 360° turns on asphalt surfaces; 2. Shoe Mating Face Cleaning: Service technicians must thoroughly remove mud, sand, and rust from metal track plates before installing new pads, ensuring bases sit completely flat with zero trapped foreign objects to prevent uneven stress and cracking.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including rubber protector disassembly diagrams, torque wrench pre-tightening parameters, locknut usage norms, and visual guides, assisting overseas technical personnel in executing standardized construction.
