YD00000317 PIN HITACHI for ZX48U-5A/4TNV88

Engineered to Secure, Locate, and Transmit Mechanical Forces

The pin is a fundamental fastening and pivot component that secures assemblies, locates components, or transmits shear and tensile loads in linkages, undercarriage, hydraulic cylinders, and structural joints. This genuine Hitachi pin is precision-machined to exact diameter, length, and tolerance specifications, ensuring proper fit within mating bores or bushings. Trust this pin to maintain accurate alignment, resist loosening under vibration, and provide reliable force transfer—enabling smooth equipment operation and extended component life.

Case-Hardened Alloy Steel with Optimized Core Toughness

Manufactured from high-strength alloy steel and precisely heat-treated, this genuine pin achieves a hard, wear-resistant surface that resists galling, scoring, and abrasion, combined with a ductile core that absorbs shock loads and resists bending or shearing. Precision-ground diameters and accurately machined retaining features (grease grooves, cross-holes, or snap-ring grooves) ensure consistent lubrication distribution and positive retention. Advanced corrosion protection—such as zinc plating or black oxide coating—provides long-term resistance to moisture, chemicals, and environmental exposure on demanding job sites.
