118-3934 and 1183934 are fully interchangeable part numbers for the same bucket cylinder. All structural dimensions match original parts completely, seamlessly connecting bucket linkages and hydraulic pipelines to guarantee stable continuous heavy-load operation under mining and quarry working conditions.
Thickened cylinder barrel and connecting lugs adopt optimized reinforcement design, capable of enduring long-term cyclic heavy loads and frequent collision impacts in harsh mining sites, greatly extending overall service life.
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.
Delivers identical stability and durability as genuine spare parts, effectively cutting recurring procurement costs for repair workshops and spare parts wholesalers.
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.
Our factory has more than ten years of mature experience in R&D and manufacturing hydraulic cylinders for classic large excavator series including 345BL II. We supply complete boom, arm and bucket cylinder assemblies with sophisti ed production craftsmanship and full-process strict quality control systems.
