One New Aftermarket Replacement Hydraulic Cylinder Wear Ring (Bushing) for Hitachi Excavators
This aftermarket replacement hydraulic cylinder wear ring (also referenced as an excavator bushing) is designed for use in the boom, arm, and bucket cylinders of Hitachi Zaxis and EX-series excavators. Wear rings serve as internal guides within hydraulic cylinders, preventing metal-to-metal contact, maintaining piston and rod alignment, and reducing side-load friction to extend overall cylinder service life. Replaces OEM part number 0310304 (item number 1-0310304).
