SGPC800SE Arm Cylinder 707-01-0A531
The SGPC800SE Arm Cylinder is a high-performance hydraulic actuator specifically engineered for the Komatsu PC800SE (Super Earthmover) series excavators. Designed as a direct replacement for OEM Part Number 707-01-0A531, this cylinder is built to handle the extreme breakout forces required in mass excavation projects.
Unlike standard cylinders, this “SE Spec” component is optimized for heavy-duty short-boom configurations, providing the structural integrity needed to drive large-capacity buckets through hard-packed earth and blasted rock.

Key Features & Performance
-
Mass Excavation Ready: Engineered specifically for the PC800SE’s high-production geometry. The cylinder wall thickness and rod diameter are optimized to withstand the intense hydraulic pressure generated during mass earthmoving cycles.
-
Impact-Resistant Rod: The piston rod features deep induction hardening to prevent surface damage from rock rebound, a common issue when using large SE-spec buckets.
-
Leak-Free Reliability: Fitted with premium NOK buffer seals, ensuring consistent pressure holding even under maximum load, reducing cycle times and boosting productivity.
-
Direct Fit Guarantee: Precision-machined mounting eyes ensure perfect alignment with the PC800SE linkage, allowing for a seamless installation of part number 707-01-0A531.
Applications
-
Mass earthmoving and large-scale infrastructure
