3. Product Advantages

  1. 100% OEM Fitment Accuracy: Every dimension and structural design strictly follows Komatsu factory specifications, ensuring perfect connection with arm linkages and hydraulic pipelines for stable operation under long-hour continuous heavy loads.
  2. Heavy-Duty Reinforced Construction: The cylinder body and joint lugs adopt optimized thickened design to withstand persistent heavy pressure and frequent impacts in harsh construction environments, effectively extending overall service lifeKomatsu.
  3. Comprehensive Pre-Shipment Quality Assurance: Each finished unit undergoes multiple rounds of full-stroke cycle operation and high-pressure tightness inspection, thoroughly eliminating hidden risks of internal and external oil leakage.
  4. Superior Cost Performance: It matches the durability and working efficiency of genuine Komatsu parts, helping equipment maintenance teams and spare parts merchants effectively lower long-term procurement costs by 30-50% compared to OEM alternatives.
  5. Flexible Global Delivery Solutions: In-stock goods can be dispatched within 3 working days. Air freight caters to time-critical orders, while sea freight is the most economical option for large batch wholesale.

5. FAQ

Q1: Can this arm cylinder fit Komatsu PC290LC-8 or PC290-8 excavator models?

A: No. Different Komatsu excavator models (especially -8 vs -8K variants) are equipped with exclusive part numbers and structural sizes, which are not interchangeable. Please confirm your equipment model and serial number before placing orders.

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

A: The seal repair kit is not included in standard products. You can purchase the matching repair kit separately (PN: 707-01-0H950K), and we will offer a favorable price for combined orders.

Q3: What packaging is used for long-distance overseas sea transportation?

A: Anti-rust oil is injected into the cylinder interior, and anti-rust grease is applied on the piston rod surface. The whole product is wrapped with waterproof PE film and packed in solid export plywood cases with reinforced corners to ensure safe delivery.

Q4: Are there preferential policies for purchasing a full set of working device cylinders?

A: Yes. Orders for complete cylinder sets (boom + arm + bucket) enjoy tiered discounts (10-15% off). We also provide consolidated shipment service to help customers cut down logistics expenses by combining multiple items into a single container.

Q5: What after-sales support will be provided if oil leakage occurs within the warranty period?

A: Please take clear photos of the leakage position and provide the excavator serial number and purchase date. We will arrange free seal replacement and professional remote troubleshooting guidance within 48 hours. If necessary, we can also dispatch a technical engineer to your site (additional charges may apply for on-site service).
