The solution to the pain points of application scenarios
Failure scenario: Hydraulic oil leakage leading to a decrease in lifting force?
→ Double-layer stepped sealing structure is adopted, and the leakage rate is <0.1ml/min
Maintenance Challenges: Frequent Seal Replacement Downtime Losses?
→ Pre-assembled seal assemblies for quick field replacement
Cost anxiety: the price of imported parts is too high?
→ The price of the same performance is only 60% of the OEM parts, and free sample testing is supported
FAQ
Q: Can you provide a comparison table of original models?
A: We have established a seal database containing 300 bulldozer models, and provide a free model query service
Q: How do I make sure that the seals are compatible with different hydraulic oils?
A: The standard material is compatible with ISO VG46 hydraulic oil, and the special medium can be customized with FKM fluoroelastomer
