Work Equipment Parts/Pin and Bush

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized pin and bush components within our work equipment parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and articulation configurations, ensuring that every component meets rigorous Komatsu standards for structural performance and preventive maintenance:
• Machine & Heavy-Duty Pin-Bushing System Compatibility: Engineered for a broad range of Komatsu excavators, our pin and bushing 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 Pin & Bushing Range: 1. High-Strength Pins: Manufactured from advanced alloy structural steels (such as 40CrMo and 42CrMo) via quenching, tempering, surface high-frequency induction hardening, and precision grinding to deliver exceptional bending and shear fatigue strength; 2. Wear-Resistant Bushings: Heavy-duty bronze and composite bushings featuring superior oil retention performance to endure massive radial alternating loads at rotational pivot points; 3. Dust Seals & Grease Kits: Critical protective barriers engineered to block fine quartz sand ingress and lock in extreme-pressure lubricating grease films.
• OEM & Aftermarket Options: Certified original equipment manufacturer Komatsu pins and bushings 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 pin and bush 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 boom, arm, and bucket pins and bushings 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 fleet workshops and minimize equipment downtime caused by pin breakage halting complete machine operations.
• Anti-Rust Coating and Vacuum Boxing: We implement specialized industrial packaging standards for the precision outer diameters and working faces of all pins and bushings utilizing heavy-duty long-lasting anti-rust oil coatings, high-strength moisture-proof vacuum plastic sealing bags for individual item isolation, and thickened crush-resistant cardboard outer boxes to ensure absolute freedom from rust and zero damage to machining accuracy during transcontinental ocean freight under salt spray and high humidity environments.
• Heavy-Duty Crated Packaging and Compartmentalization: Bulk heavy-duty pin and bushing shipments are packed securely inside high-strength export fumigated solid wood crates featuring internal high-density shock-absorbing foam compartmentalization and limit-fixing slots to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without collision or impact damage.
• Consolidated Sourcing for Overhaul Kits: We support overseas clients by consolidating large pin and bushing sets alongside matching full sets of bucket teeth, buckets, track chain assemblies, and track rollers into precise bundled excavator overhaul kits, achieving a one-stop purchasing model that pairs heavy structural work equipment assemblies 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 Pin & Bushing Durability Solutions: We address extreme jobsite challenges—such as granite crushed stone and abrasive open-pit iron mines—where original pins suffer early surface flaking or bushings experience accelerated wear under high-frequency impact rotation. We also provide professional engineering upgrades utilizing high-purity alloy steel treated through deep induction hardening, surface chrome plating, or carburizing, paired with high-load self-lubricating composite bushings.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for joint abnormal noises or pin spinning inside bosses. This focuses on two critical protocols: 1. Greasing & Clearance Monitoring: Enforce high-temperature extreme-pressure grease injection every shift during heavy mining work to purge quartz sand invading pin gaps, strictly prohibiting dry grinding that leads to pin-bushing seizure; 2. Boss Bore Repair & Boring: When minor out-of-roundness appears in boom or arm boss bores, technicians must replace bushings promptly or execute professional field buildup welding and line boring, strictly prohibiting continued operation with large clearances to prevent stress concentrations from tearing structural bosses.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including pin disassembly hydraulic tool diagrams, thermal installation norms (freezing/heating), grease injection standards, and visual guides, assisting overseas technical personnel in executing standardized construction.
