SGEX1200 Backhoe Bucket Cylinder 4438245

The SGEX1200 Backhoe Bucket Cylinder is a heavy-duty hydraulic actuator manufactured by SEIGO Machinery for the Hitachi EX1200 Mining Excavator series (EX1200-5, EX1200-6). Designed as a precise aftermarket replacement for OEM Part Number 4438245, this cylinder provides the essential digging power required for mass excavation and truck loading.

Built to withstand the high-cycle demands of backhoe operations, our cylinder features an induction-hardened rod to resist impact damage from rock faces and advanced sealing systems to prevent internal leakage under load.

Technical Specifications

Key Features & Performance

• Hitachi Backhoe Geometry: Engineered strictly to the dimensions of part number 4438245, ensuring the correct bucket curling angle and breakout force for EX1200 backhoe attachments.

• Maximum Digging Power: The cylinder barrel is constructed from high-tensile steel to handle the maximum hydraulic system pressure (350 Bar+) without expansion, delivering consistent penetration power in hard ground.

• Debris Protection: The piston rod is surface-hardened to HRC 55-60 to resist scratches from falling debris, while the wiper seals are upgraded to prevent coal dust and grit from entering the system.

• Long-Life Durability: Equipped with premium NOK seals capable of withstanding the heat generated during continuous loading cycles in mining environments.

Applications

• Mass excavation (Coal, Overburden)

• Quarry truck loading

• General heavy construction
