3. Product Advantages
100% OEM Interchangeable Fit
Two part numbers are fully interchangeable. All dimensions match original parts perfectly, well connected with arm linkages and hydraulic pipelines for stable long-hour heavy-load operation.
Thickened Reinforced Heavy-Duty Structure
The cylinder tube and connecting lugs adopt reinforced thick design, resisting frequent impact and cyclic heavy loads in harsh construction and quarry environments to extend service life greatly.
Strict Multi-Round Pre-Delivery Inspection
Every finished cylinder goes through full-stroke recipro ing cycle test and high-pressure air tightness inspection to eliminate internal and external oil leakage risks completely.
Excellent Cost Performance
Same stability and service life as genuine spare parts, effectively cutting procurement costs for repair shops and spare parts distributors.
Flexible Global Shipping Options
In-stock items can be shipped out within 3 working days. Air freight for urgent orders; sea freight for cost-saving bulk wholesale.

5. Common FAQ
Q1: Can this arm cylinder fit 320, 320B or 320N excavators?
A: No. Each model uses exclusive part numbers and unique structural sizes without interchangeability. Please confirm your machine model before ordering.
Q2: Does the standard package include the seal repair kit?
A: Seal kit is not included in standard goods. You can buy the matching seal kit separately, and we will offer a discounted price for combined orders.
Q3: How is the product packed for long-distance sea transport?
A: Anti-rust oil filled inside cylinder, anti-rust grease coated on piston rod. Wrapped with waterproof PE film and packed in reinforced export plywood cases to avoid collision and damp damage during ocean transit.
Q4: Will we get discounts if buying a full set of boom + arm + bucket cylinders?
A: Yes, tiered volume discounts for full working device cylinder sets. Combined container shipment service is available to lower total logistics cost.
Q5: What after-sales service for oil leakage within warranty?
A: Please provide clear photos of leakage position and excavator serial number. We will arrange free seal replacement and professional remote technical guidance promptly.
