Product Description
Kobelco SK210-8 / SK210LC-8 Stick Hydraulic Cylinder | PN:YN01V00172F1 | Mid-Heavy Construction Aftermarket Replacement
1.Product Brief

This heavy-duty dipper arm hydraulic cylinder is a direct bolt-on aftermarket replacement specially developed for Kobelco SK210-8 standard chassis excavator and long-track SK210LC-8 medium construction digger. As the core hydraulic component controlling arm extension and retraction, it provides powerful stable digging force for municipal road renovation, residential foundation excavation, pipeline trenching and medium aggregate stockyard loading. It is a must-stock spare for equipment repair workshops, medium excavator rental fleets and cross-border spare parts suppliers focusing on classic Kobelco 8-series medium excavators.

All manufacturing processes strictly follow Kobelco original OEM engineering drawings and precise assembly tolerances. Mount lug spacing, pin hole diameter, wear-resistant copper bushing size and hydraulic port layout fully match dedicated OEM part number YN01V00172F1. Plug-and-play installation without on-site cutting, grinding or welding rework, greatly cutting maintenance labor cost and avoiding construction downtime caused by sudden cylinder failure.

Core Competitive Advantages
  1. Universal Dual-Chassis Fit for SK210-8 & SK210LC-8 Classic Models
    This stick cylinder assembly perfectly fits both standard and long-frame SK210-8 variants without dimensional deviation. All connecting geometric sizes fully replicate genuine Kobelco 8-series OEM components, seamlessly matching factory arm linkages and original hydraulic pipelines. It completely eliminates assembly offset issues that trigger premature seal aging and persistent oil leakage due to forced installation on aged reinforced machine frames.
  2. 8-Series Classic Excavator Targeted Reinforced Anti-Impact Structure
    Different from low-cost generic thin-wall hydraulic cylinders, this model optimizes cylinder tube and cast lug wall thickness according to the high-frequency medium-load working characteristics of Kobelco SK210-8 series. It withstands long-term alternating construction loads and accidental hard object collisions, delivering far longer service life than non-reinforced universal aftermarket alternatives.
  3. Two Independent Offline Pre-Delivery Inspections Eliminate Hidden Quality Risks
    Each finished stick cylinder undergoes two strict offline testing flows before leaving the factory. Full-stroke reciprocating fatigue test simulates months of non-stop municipal earthmoving to verify integral structural rigidity; long-duration high-pressure soaking tightness inspection comprehensively scans all internal and external leakage points. All unqualified products are fully screened out before warehousing to prevent unexpected construction shutdown losses for end users.
  4. High Cost Performance for Fleets Equipped with Kobelco SK210-8 Series Diggers
    Genuine OEM spare parts for discontinued classic SK210-8 series have high prices and long supply lead times. This aftermarket stick cylinder reaches equivalent structural toughness, stable low-vibration operation and service life as original Kobelco parts at a competitive unit price, significantly reducing long-term repeated maintenance costs for repair shops and medium rental enterprises with batches of SK210-8 excavators.
  5. Flexible Global Logistics Solutions to Meet Diversified Client Delivery Demands
    All in-stock goods can be dispatched within 3 working days after payment confirmation. Air freight supports emergency rush orders for sudden machine breakdowns at remote suburban construction sites; consolidated bulk sea freight and full FCL container transport provide budget-friendly wholesale shipping plans for machinery distributors covering construction markets across Africa, Southeast Asia, the Middle East and Latin America.

Regular Customer FAQ

Q1: Can this stick cylinder fit Kobelco SK210-9 or SK240LC-8 excavators?
A: Cross-model installation is not supported. Different generations and models of Kobelco excavators adopt exclusive OEM part numbers and unique lug mounting geometric dimensions without interchangeability. Please double-check your full machine model before placing orders.

Q2: Does standard delivery package include the matching seal repair kit?
A: Standard packaging only contains the complete dipper arm cylinder assembly. The dedicated YN01V00172F1-KIT seal kit must be purchased separately, and we offer discounted bundled pricing for customers ordering cylinder and seal kit together.

Q3: What anti-rust and anti-collision protective measures are adopted for long-distance ocean transportation?
A: Anti-rust hydraulic oil is fully injected into front and rear cylinder chambers to block internal corrosion; thick anti-rust grease is evenly coated across the entire exposed piston rod surface. The whole cylinder assembly is wrapped with multi-layer heavy waterproof PE film and fixed inside reinforced thick plywood export crates to avoid scratches, impact deformation and moisture erosion during lengthy cross-ocean transit.

Q4: Are tiered volume discounts available when purchasing a full boom + arm + bucket cylinder set for SK210-8 series?
A: Yes. Orders for complete front working device cylinder sets enjoy progressive bulk purchase discounts. Consolidated full-container sea shipping service is also supported to cut overall international logistics costs for large batch orders.

Q5: What after-sales technical support can I obtain if oil leakage occurs within the 12-month warranty period?
A: Please provide clear photos of the leakage position and excavator serial number for verification. We will arrange free replacement sealing accessories and detailed step-by-step remote maintenance guidance timely to solve leakage faults rapidly without delaying municipal construction progress.
