This high-performance aftermarket hydraulic stick cylinder is precision manufactured as a direct OEM replacement for early Komatsu PC150 base model and PC150-1 medium excavators. As the core hydraulic drive component of front working equipment, it controls arm extension and retraction to finish digging, grabbing, loading and site leveling tasks. Widely used in municipal works, road maintenance, landscaping, pipeline laying and light earthmoving projects.
All cylinders are produced strictly following Komatsu original technical drawings and OEM standards, with fully consistent mounting dimensions, pin hole pitch and hydraulic oil port layout. Direct bolt-on installation without cutting, welding or any field secondary modification.
