3. Product Advantages

1. Two OEM Part Numbers Fully Interchangeable

   21K-63-X2110 and 21K-63-X2100 correspond to the same bucket cylinder assembly, perfectly matching Komatsu PC150-5 excavator. All connecting sizes fully match original OEM parts, seamlessly connected with bucket linkages and hydraulic hoses to support stable continuous medium-load construction work.

2. Medium-Load Reinforced Structure Design

   Thickened cylinder tube and integrated lug plates are optimized for daily construction and light quarry conditions, resisting long-term cyclic loads and minor collision abrasion 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

   It delivers equivalent stability and service life as genuine Komatsu OEM spare parts, greatly lowering repeated procurement costs for repair shops, equipment rental fleets and global spare parts wholesalers.

5. Flexible Global Logistics Support

   In-stock goods can be dispatched within 3 working days. Air freight is available for urgent breakdown orders; sea freight provides cost-saving bulk wholesale shipping for Africa, Southeast Asia, Middle East and Latin American markets.

5. FAQ

Q1: Can this bucket cylinder fit Komatsu PC120-5 or PC160-5 excavators?

A: No. Different Komatsu excavator models use 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 is filled into the cylinder inner cavity, anti-rust grease evenly coated on piston rod surface. The whole cylinder is wrapped with thick waterproof PE film and packed in reinforced export plywood cases to prevent scratches, collision and moisture damage during long sea transit.

Q4: Are there tiered volume discounts when purchasing a full set of boom + arm + bucket cylinders?

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 the leakage position plus excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance promptly.
