Chassis Parts/Axle

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of axle assemblies and core internal transmission components to support diverse wheel loader, grader, and truck requirements:
• Machine & Axle System Compatibility: Engineered for a broad range of Caterpillar equipment—including wheel loaders (e.g., CAT 950, 966, 980, 988), motor graders (e.g., CAT 140, 160), and articulated trucks (e.g., CAT 725, 730)—our parts ensure exact dimensional and functional alignment with original factory main reduction gear assemblies, differentials, axle shafts, planetary hubs, and axle housings to guarantee a perfect match.
• Complete Axle Assemblies & Components: 1. Differentials & Final Drives: Bevel gear sets, differential cases, spider crosses, planetary gears, and side gears; 2. Axle Shafts & Spindles: High-strength alloy steel forged axle shafts, steering spindles, and wheel hub bearing assemblies; 3. Planetary Hubs & Sealing Kits: Planetary reduction gears, ring gears, duo-cone floating seals, and high-pressure oil seal kits.
• OEM & Heavy-Duty Aftermarket: We offer genuine Caterpillar axle assemblies and precision parts alongside rigorously tested heavy-duty aftermarket components manufactured from premium carburized alloy steel with precision gear profiling, delivering equivalent transmission efficiency and extended fatigue life at a cost-effective price point for global fleets.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global machinery axle component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Ready-to-Ship Inventory: We maintain large-volume stock of high-demand CAT axle shafts, differential repair kits, planetary reduction gears, and floating seals, ensuring direct dispatch upon order confirmation to minimize unplanned equipment downtime caused by powertrain system failures.
• Heavy-Duty Anti-Rust and Secure Packaging: We implement specialized industrial packaging standards for heavy cast steel axle housings and high-precision gears, utilizing anti-rust oil film spraying, vapor corrosion inhibitor bag sealing, and custom solid wood crates or fumigation-free steel-banded wooden pallets to ensure parts withstand ocean and land transit without seawater erosion or heavy impact damage.
• Consolidated Heavy Cargo Sourcing: We support overseas clients by consolidating heavy axle assemblies or shafts alongside brake discs, wheel hub bearings, and other chassis peripheral parts into scientific mixed container loads, maximizing container weight and space limits while significantly reducing international freight costs.

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.
• Application-Specific Durability Solutions: We address common field issues in extreme working environments, such as high-load open-pit mines, steep-grade rock hauling, and overloaded operations, where axle shafts experience frequent torsional fatigue fractures, main drive hypoid gears suffer from early pitting spalling, and floating seals fail from abrasive mud intrusion. We also provide professional engineering upgrades, including high-toughness fatigue-resistant alloy axle shafts, carburized heavy-duty gear sets, and dual-face dust-resistant mud-blocking floating seals.
• Axle Troubleshooting and Diagnostics: We address common user concerns regarding axle faults by providing professional diagnostic and replacement guidance. This includes instructions on how to measure main reduction gear backlash and tooth contact patterns to prevent secondary damage caused by improper adjustments, alongside installation specifications for floating seal orientation and bearing preload settings to resolve hub reduction leaks and bearing noise.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering axle assembly lifting safety protocols, component bolt torque specifications, and routine gear oil replacement maintenance recommendations.
