Product Description
Our premium CAT E330D bucket cylinder piston rod, OEM replacement Cat 330D arm hydraulic rod, overhaul spare OEM E330D digger bucket ram shaft, high-strength 42CrMo hard chrome cylinder rod, dedicated E330D excavator bucket repair spare and anti-abrasion high wear resistant hydraulic piston rod is core force transfer part for Cat E330D/330DL excavator bucket hydraulic cylinder, matching original OEM part number series:2426767,2254578. Adopt solid 42CrMo alloy steel blank via overall quenching + 0.03mm thick hard chrome plating, strictly produce per CAT original drawing dimension standard. This piston rod stretches & retracts repeatedly to convert hydraulic pressure into digging power for bucket grabbing soil & rock; it is widely used to replace scratched, bent, chrome peeling, fatigue fractured original rod which causes oil leakage, bucket slow action, hydraulic system overheating. Factory spot inventory supports global machinery distributors, local excavator repair shop and engineering fleet bulk procurement.
- 42CrMo steel bar incoming spectrum inspection, chemical composition & tensile strength lab test, eliminate inferior recycled steel.
- Whole blank quenching & tempering treatment to optimize inner metal toughness, release raw material internal stress.
- Multi-pass CNC lathe rough & finish turning to control outer diameter tolerance within h8 standard.
- Pre-grinding rod surface before electroplating to improve chrome bonding adhesion.
- Automatic hard chrome electroplating, constant current control to ensure uniform coating thickness.
- Post-chrome precision cylindrical grinding to reach mirror finish and strict dimensional precision.
- Full dimension & hardness sampling inspection before finished packaging.
- Piston fixed on middle position of piston rod divides cylinder inner chamber into front & rear oil cavity.
- High-pressure hydraulic oil alternately feed two chambers, produce pressure difference to push rod stretch out & retract back.
- Rod head connect with bucket link, convert hydraulic thrust into mechanical force to finish bucket digging, loading action.
- Smooth chrome surface slide through dust wiper & rod seal, scrape off dirt and keep hydraulic oil sealed inside cylinder.
- Alloy base bear frequent tensile & impact force from bucket heavy-load excavation.
- 7*24h online technical consultation: model check, installation guidance, failure analysis for global purchasers.
- Three-step pre-delivery QC: raw material test→size & hardness detection→surface appearance inspection.
- OEM customization: customer private logo print on wooden case, customized non-standard length production.
- Multiple logistics option: sea freight, air shipment, international express with full tracking number.
- One-stop E330D full cylinder spare supply: cylinder tube, seal repair kit, piston, guide sleeve all in stock.
- Lifelong free after-sale technical support for abnormal rod wear & premature oil leakage troubleshooting.
