07156-02022 Wear Ring Fits Komatsu Models

One New Aftermarket Replacement Wear Ring for Komatsu Construction Equipment

This aftermarket replacement hydraulic wear ring (also called a guide ring) fits the hydraulic cylinder assemblies on a wide range of Komatsu construction equipment, including excavators, bulldozers, wheel loaders, and compactors. The wear ring guides the piston and rod within the hydraulic cylinder, absorbing lateral and transverse forces while preventing metal-to-metal contact between moving components. Proper wear ring condition protects cylinder walls, reduces seal wear, and maintains hydraulic system performance.
