4724236H BUSHING HITACHI for ZX330-5A/6HK1T

Engineered to Reduce Friction, Absorb Shock, and Maintain Alignment

The bushing is a critical precision component that provides a low-friction, wear-resistant bearing surface for rotating, oscillating, or sliding components—including pins, shafts, and pivot joints in linkages, undercarriage, and hydraulic cylinders. This genuine Hitachi bushing is precision-machined to exact inner and outer diameter tolerances, ensuring consistent clearance and proper load distribution across the entire bearing interface. Engineered to absorb shock loads, reduce vibration, and maintain accurate alignment, this bushing protects mating components from premature wear and extends the service life of your equipment's most critical moving assemblies.

Optimized Metallurgy or Engineered Composites for Your Specific Application

Manufactured from premium materials selected for your specific application—such as oil-impregnated bronze for continuous lubrication, hardened alloy steel for high-impact environments, PTFE-lined metal for low-friction operation, or engineered polymers for corrosion resistance—this genuine bushing delivers exceptional resistance to galling, corrosion, and deformation under shock loads. The precisely controlled running surface promotes even load transfer and consistent lubrication retention, reducing friction and heat generation. Whether used in high-cycle articulation joints or heavy-load hydraulic mounts, this bushing maintains dimensional stability across a wide temperature range, ensuring reliable performance in harsh job site conditions.

Genuine Hitachi: Maintain Precision, Maximize Component Life, and Avoid Costly Rebuilds

A worn, improperly sized, or poorly manufactured bushing introduces excessive clearance and play into mechanical linkages, leading to misalignment, accelerated pin and seal wear, uneven load distribution, noise, and compromised machine performance. Aftermarket bushings often suffer from improper clearances, inferior materials, poor surface finish, or inadequate hardness that dramatically shortens service life and increases maintenance frequency. This genuine Hitachi component is manufactured to meet all original equipment specifications for material composition, hardness, dimensional accuracy, and surface finish—ensuring a precise fit that restores factory performance. Protect your equipment's pivot joints, extend rebuild intervals, and ensure reliable operation with the bushing engineered specifically for Hitachi durability.
