One cylinder fits both standard-track PC220-5 and long-track PC220LC-5. All assembly sizes, lug spacing and oil port positions fully match original PN 206-63-X2120 cylinder, seamlessly connecting arm linkages and hydraulic pipelines to guarantee stable medium-heavy load continuous operation.
Thickened cylinder tube and joint lugs are optimized for quarry and construction harsh working conditions, resisting long-term cyclic loads and accidental rock collision to extend service life greatly.
Each finished cylinder undergoes repeated full-stroke reciproing cycle test and high-pressure airtight leak detection, thoroughly eliminating hidden internal and external oil leakage risks.
It achieves the same stability and service lifespan as genuine Komatsu OEM spare parts, effectively lowering recurring procurement costs for repair shops, equipment rental fleets and global spare parts wholesalers.
In-stock goods can be dispatched within 3 working days. Air freight for urgent breakdown orders; sea freight for low-cost bulk wholesale shipments to Africa, Southeast Asia and Middle East markets.
Our factory has over 10 years of mature experience in R&D and manufacturing hydraulic cylinders for classic Komatsu PC series excavators including PC220-5 / PC220LC-5. We supply complete boom, arm and bucket cylinder assemblies with mature forging, honing and heat treatment technology, plus full-process strict quality control.
