3065991 BUSHING HITACHI for ZX120-3/4JJ1T

Precision Pivot Support and Friction Reduction – The Critical Component for Articulation and Longevity.

This genuine Hitachi bushing is a precision-machined component that provides a low-friction bearing surface for pins, shafts, and pivot joints in linkages, undercarriage, and hydraulic cylinders. Available in multiple OEM configurations including 152602730 (140x120mm, 120mm length), 26756-12451 (0.12kg), and 4197842, it ensures consistent clearance, proper load distribution, and smooth articulation across critical pivot points. In applications like the ZX330-1 arm cylinder, DU bushings provide structural reinforcement for the arm joint, reducing metal-to-metal contact and extending service life.

Superior Materials and Precision Engineering – Built to Withstand Shock, Wear, and Harsh Environments.

Manufactured from high-grade materials including oil-impregnated bronze, hardened steel, PTFE-lined composites, or DU bushings (composite PTFE-lined metal) depending on the application, this bushing offers exceptional resistance to galling, corrosion, and deformation under shock loads. Precision-ground running surfaces promote even load transfer and consistent lubrication retention, reducing friction and heat generation. Available in configurations for EX and ZX series excavators, LX series wheel loaders, as well as applications like ZX25 track roller bushings (3056041), ZX60-3 boom cylinders (1187203), and a wide range of EX100 to EX550 models (0994204). Many variants feature grease-retention grooves for continuous lubrication and advanced anti-corrosion coatings for demanding job site environments.
