3. Product Advantages
Dual PN Universal Interchange Fitment
118-4124 and 1184124 represent the same bucket cylinder assembly. All structural sizes fully match original components, seamlessly connecting bucket linkages and hydraulic pipelines for stable long-hour continuous heavy-load operation.
Medium-Heavy Reinforced Structure
Thickened cylinder barrel and connecting lugs are optimized for harsh quarry and construction sites, resisting long-term cyclic loads and accidental collisions to greatly extend service life.
Multi-Round Strict Pre-Delivery Inspection
Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, thoroughly eliminating hidden risks of internal and external oil leakage.
Excellent Cost Performance
Delivers identical stability and durability as genuine spare parts, effectively cutting repeated procurement costs for repair shops and spare parts wholesalers.
Flexible Global Logistics Solutions
In-stock goods can be dispatched within 3 working days. Air freight meets urgent delivery demands, while sea freight provides the most cost-effective solution for bulk wholesale orders.

5. FAQ
Q1: Can this bucket cylinder fit 320BL or 325BL excavators?
A: No. Different excavator models adopt exclusive part numbers and unique structural dimensions without interchangeability. Please confirm your complete excavator model before placing orders.
Q2: Does the standard package include the matching seal repair kit?
A: The seal repair kit is not included in standard delivery. You can purchase the dedi ed supporting seal kit separately, and we will offer a competitive combined order quotation.
Q3: What packaging is adopted for long-distance overseas sea transportation?
A: Anti-rust oil is injected into the cylinder inner cavity, anti-rust grease evenly coated on piston rod surface; the whole cylinder wrapped with waterproof PE film and packed in reinforced export plywood cases to avoid collision and moisture damage during ocean transit.
Q4: Are there tiered volume discounts for purchasing a full set of boom + arm + bucket cylinders?
A: Yes. Complete cylinder set orders enjoy graded preferential pricing. Consolidated container shipment service is also available to lower total logistics expenses.
Q5: What after-sales technical support is available if oil leakage occurs within warranty?
A: Please provide clear photos of leakage position and excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance promptly.
