Other General Parts/Wheel Related Parts

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized wheel-related parts within our Other General Parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and wheel-end configurations, ensuring that every component meets rigorous Komatsu standards for load containment and preventive maintenance:
• Machine & Heavy-Duty Wheel-End Compatibility: Engineered for a broad range of Komatsu heavy-duty wheel loaders and motor graders, our products ensure exact material strength ratings, dimensional tolerances, and bolt pattern interfaces for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty Wheel-End Range: 1. Wheel Hubs & Rims: Designed to withstand massive vertical loads and lateral overturning forces with extra-thick wall impact resistance for primary travel load-bearing units; 2. High-Tensile Wheel Studs & Nuts: Formulated to endure high-frequency alternating shear stresses and prevent rim loosening under extreme operating conditions; 3. Wheel Planetary Reduction Assemblies & Internal Gears: Satisfying final large-ratio speed reduction and torque multiplication directly at the wheel ends.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu wheel-end parts alongside rigorous high-performance aftermarket alternatives featuring reinforced alloy materials, delivering exceptional 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 wheel-end 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 tens of wheel hubs, rims, and wheel reduction assemblies matching Komatsu mainstream wheel loaders. 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 wheel-end fractures or gear breakage halting complete machine operations.
• Anti-Rust Sealing and Edge Protection: We implement specialized industrial packaging standards for precision-machined surfaces, bearing seats, and tire bolt threads of all wheel hubs and wheel-end assemblies utilizing heavy-duty long-lasting anti-rust oils, thick industrial bubble wrap, and multi-layer wrapping films, while custom anti-collision corner protectors are installed along rim edges to ensure zero thread corrosion or flange deformation during transcontinental ocean freight under salt spray and high humidity environments.
• Heavy-Duty Crated Protection: Bulk heavy-duty wheel hub and wheel reduction shipments are packed in high-strength export fumigated wooden crates with cross-braced timber blocks and high-strength bolts suspending heavy units off the container floor to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without deformation.
• Consolidated Sourcing for Wheel-End Overhaul Kits: We support overseas clients by consolidating large wheel hub assemblies alongside matching full sets of high-strength tire studs and nuts, high-pressure-resistant wheel-end oil seals, precision bearings, and specialized heavy-duty gear oils into precise bundled full-set wheel-end maintenance kits, achieving a one-stop purchasing model that pairs wheel-end 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 Wheel-End Durability Solutions: We address extreme jobsite challenges—such as heavy rock blasting and muddy open-pit mines—where original rims develop fatigue cracks near valve stem holes or flanges under harsh road conditions, and tire bolts snap under severe shear stress. We provide professional engineering upgrades utilizing thickened alloy steel forgings, fatigue-resistant reinforced rib structures, and hardened tire studs.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like rhythmic wheel-end noises, rusty water leaks at flange plates, or gear breakage. This focuses on two critical protocols: 1. Bolt Torque Inspection & Oil Protection: Technicians must fully re-torque all tire bolts within the first 50 hours of operation for new machines or replaced studs—preventing loose bolts from forcing adjacent ones into collective shear failure—while strictly monitoring wheel reduction gear oil to prevent muddy water ingress; 2. Bearing Clearance Adjustment: Service technicians must adjust bearing pre-tightening clearances strictly according to Komatsu manuals, prohibiting over-tightening (which causes high-temperature bearing burnout) or under-tightening (which causes hub play).
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including wheel hub disassembly diagrams, bolt cross-diagonal pre-tightening torque standards, oil seal installation guide sleeve specifications, and visual guides, assisting overseas technical personnel in executing standardized construction.
