Maintenance Parts/Grease

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized greases within our maintenance parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and lubrication configurations, ensuring that every component meets rigorous Komatsu standards for friction control and preventive maintenance:
• Machine & Heavy-Duty Grease Application Compatibility: Engineered for a broad range of Komatsu heavy-duty equipment, our products ensure exact consistency grades, additive formulations, and pumpability thresholds for a 100% perfect match, rapid greasing, and factory-grade performance.
• Complete Heavy-Duty Grease Range: 1. Multi-Purpose Greases: Conforming to strict Komatsu engineering standards to provide reliable friction control and wear protection for high-load pins and bushings; 2. Extreme Water-Resistant EP Mining Greases: Specially formulated for wet operations, rainy seasons, and high-impact loads like hydraulic breakers, ensuring anti-emulsification and non-washout performance; 3. Auto-Lube Cartridges & Bulk Greases: Satisfying standard cartridge and bulk drum requirements for high-pressure delivery across medium-to-large Komatsu excavators and mining trucks.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu greases alongside rigorous high-performance aftermarket alternatives, 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 grease 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 hundreds of metric tons of high-performance heavy-duty greases matching Komatsu mainstream models. 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 grease shortages leading to dry-friction pin seizure.
• Thermal Sealing and Maritime Compliance: We implement specialized industrial packaging standards for grease products featuring high-seal leak-proof double press lids alongside high-temperature high-strength engineering plastic or painted iron drums. Shipments strictly adhere to international maritime chemical general cargo compliance declarations and anti-tilt secured packaging to completely eliminate high-temperature oil separation or drum indentation during transit.
• Palletized and Heavy-Duty Crated Protection: Bulk drum and boxed greases are stacked on standardized pallet configurations, secured with high-strength stretch wrap in a criss-cross pattern, and reinforced with heavy-duty wooden corner guards or container bracing. This ensures absolute protection against toppling, deformation, or packaging damage during transcontinental ocean logistics under salt spray, high temperatures, and long-distance transport jolts.
• Consolidated Sourcing for Pin and Bushing Overhaul Kits: We support overseas clients by consolidating greases alongside matching heavy-duty pins, bushings, high-pressure grease guns, and grease fittings into precise bundled full-set pin and bushing lubrication kits, achieving a one-stop purchasing model that pairs undercarriage lubrication 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 Chassis Lubrication Solutions: We address extreme jobsite challenges—such as humid rainforests, wet quarries, and frequent hydraulic breaker operations—where ordinary greases wash away rapidly upon water contact or heavy impact, causing severe scoring and loosening on Komatsu boom and arm pins within hundreds of operating hours. We also provide professional upgrades using complex lithium or calcium sulfonate-based heavy-duty greases featuring superior water washout resistance, high EP properties, and solid anti-wear components.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like blocked grease points, auto-lube system alarms, or pin joint abnormal noises. This focuses on two critical protocols: 1. Dynamic Purging & Regreasing: Technicians must pump grease continuously while equipment operates or joints experience light loads until contaminated old grease is completely purged, strictly prohibiting surface-only greasing that leaves internal friction points dry; 2. Auto-Lube Consistency Matching: Equipment directors must select NLGI 0 or 1 fluid greases for auto-pumps, strictly forbidding the use of overly thick NLGI 2 manual greases which cause high-pressure pipeline bursts or blockages.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including pin, swing gear ring, and auto-lube point distribution diagrams, lubrication interval charts, grease gun operating specifications, and chassis lubrication troubleshooting reference documents, assisting overseas technical personnel in executing standardized maintenance.
