| Bore Diameter | 145mm |
| Piston Rod Diameter | 94mm |
| Working Stroke | 1540mm |
| Rated Working Pressure | 31.4MPa |
| Factory Test Pressure | 47.1MPa (1.5 times rated working pressure) |
| Barrel Material | High-tensile seamless alloy steel with precision inner honing |
| Piston Rod | 40CrMo heat-treated steel, 28~32μm hard chrome plating, HRC68–72, excellent wear resistance & anti-bending performance |
| Matching Seal Kit PN | 207-63-53120K |
| Working Temperature | -25℃ ~ +85℃ |
| Structure Feature | Double heavy-duty ear lugs with quenched copper wear bushings, built-in buffer device to reduce strong impact during reciproing movement |
Perfectly compatible with both PC300-5 and PC300LC-5 long-track version. All assembly sizes, lug spacing and oil port positions fully match original PN 207-63-53120 cylinder, seamlessly connecting boom linkages and hydraulic pipelines for stable long-hour heavy-load mining operation.
Thickened cylinder tube and reinforced joint lugs are specially optimized for harsh mine and quarry environments, resisting long-term cyclic heavy loads, rock collision impacts and abrasion to greatly extend service life.
Each finished cylinder undergoes repeated full-stroke reciproing cycle test and high-pressure airtight leak detection, completely eliminating hidden internal and external oil leakage hazards.
Delivers identical stability, strength and service lifespan as genuine Komatsu OEM spare parts, effectively cutting recurring procurement costs for mining repair shops, machinery rental fleets and global spare parts wholesalers.
In-stock items can be dispatched within 3 working days. Air freight supports urgent breakdown rush orders; sea freight provides cost-saving bulk wholesale shipping for Africa, Southeast Asia, Middle East and Latin American mining markets.
