3. Product Advantages

  1. Universal Fit for Two Zero-Tail Models

    Compatible with standard track PC228US-3 and long-track PC228USLC-3 short-swing excavators. All assembly sizes, lug spacing and oil port positions fully match original PN 22U-63-02633 cylinder, seamlessly connecting bucket linkages and hydraulic pipelines for stable continuous medium-heavy load operation in compact construction spaces.

  2. Optimized Reinforced Structure for Urban Zero-Tail Machines

    Thickened cylinder barrel and joint lugs are customized for frequent narrow-space work, resisting cyclic loads and wall/stone minor collisions to extend service life effectively.

  3. Multi-Round Strict Pre-Delivery Inspection

    Each finished cylinder undergoes full-stroke reciprocating cycle test and high-pressure airtight leak detection, completely eliminating hidden internal and external oil leakage risks.

  4. Outstanding Cost Performance

    Delivers identical stability and service lifespan as genuine Komatsu OEM spare parts, greatly cutting repeated procurement costs for repair shops, urban equipment rental fleets and global spare parts wholesalers.

  5. Flexible Global Logistics Support

    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 markets.

5. FAQ

Q1: Can this bucket cylinder fit Komatsu PC228US-2 or PC228US-8 excavators?

A: No. Different generations of Komatsu short-tail excavators adopt exclusive part numbers and unique structural dimensions without interchangeability. Please confirm your complete machine model before ordering.

Q2: Does the standard package include the matching seal repair kit?

A: Seal repair kit is not included in standard delivery. You can purchase the dedicated supporting seal kit separately, and we will offer a competitive combined order quotation.

Q3: How is the cylinder packed for long-distance ocean transportation?

A: Anti-rust oil filled into cylinder inner cavity, anti-rust grease evenly coated on piston rod surface. The whole cylinder wrapped with thick waterproof PE film and packed in reinforced export plywood cases to avoid scratch, collision and moisture damage during long sea transit.

Q4: Are there tiered volume discounts for purchasing a full set of boom + arm + bucket cylinders for PC228US-3 series?

A: Yes. Complete working device cylinder set orders enjoy graded volume discounts. Consolidated FCL container shipment service is available to reduce total logistics expenditure.

Q5: What after-sales technical support if oil leakage occurs within the 12-month warranty period?

A: Please provide clear photos of leakage position plus your excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance promptly.
