7. Failure Analysis & Prevention Strategies
Understanding why MTS oil chains fail is crucial for developing effective prevention strategies. Over my 18 years of experience, I have analyzed hundreds of failed chain components, identifying common failure modes and developing solutions to prevent them. In this section, I share my insights on the most common failure modes and how to avoid them.
Common Failure Modes
Wear Failure
Wear is the most common failure mode, typically occurring at the pin-bushing interface:
- Causes: Inadequate lubrication, contamination, improper installation
- Symptoms: Increased clearance, noise, vibration, reduced efficiency
- Detection: Periodic measurement of chain elongation
- Prevention: Regular lubrication, contamination control, proper installation
Fatigue Failure
Fatigue failure occurs due to repeated cyclic loading over time:
- Causes: Overloading, improper tension, misalignment
- Symptoms: Sudden fracture with characteristic fatigue striations
- Detection: Ultrasonic testing, magnetic particle inspection
- Prevention: Proper loading, correct tensioning, alignment checks
Corrosion Failure
Corrosion weakens the material and accelerates other failure modes:
- Causes: Moisture, chemicals, saltwater exposure
- Symptoms: Pitting, rust, reduced cross-sectional area
- Detection: Visual inspection, thickness measurements
- Prevention: Protective coatings, corrosion-resistant materials

8. Frequently Asked Questions
Technical Questions
Q: What is the expected service life of MTS oil chains?
A: The service life of MTS oil chains depends on operating conditions, maintenance practices, and the specific application. In typical construction applications with proper maintenance, our MTS oil chains can last 85% longer than standard dry chains, typically 12-18 months in heavy use. In our 2025 desert construction project, we achieved 14 months of service life under extreme conditions.
Q: How often should MTS oil chains be lubricated?
A: Our MTS oil chains feature a sealed lubrication system that requires minimal maintenance. Under normal operating conditions, we recommend oil changes every 6 months or 1,000 operating hours, whichever comes first. In extreme environments like deserts or arctic conditions, more frequent oil changes may be necessary. Our 2025 test data shows that proper lubrication intervals can extend service life by up to 30%.
Q: What is the minimum tensile strength (MTS) rating?
A: Our standard MTS oil chains have a minimum tensile strength of 1,200 kN per chain section, which exceeds the requirements of most bulldozer manufacturers. For specialized applications requiring higher strength, we offer custom solutions with MTS ratings up to 2,000 kN. All our chains are 100% tested to verify they meet or exceed their rated MTS.
Q: Can MTS oil chains be repaired or must they be replaced?
A: In most cases, MTS oil chains can be repaired if the damage is detected early. Our repair process includes disassembly, component inspection, replacement of worn parts, re-lubrication, and reassembly. However, if there is significant wear or structural damage, replacement is recommended. Our 2025 cost analysis shows that timely repairs can save up to 50% compared to full replacement.
Application & Customization
Q: Can MTS oil chains be customized for specific applications?
A: Yes, we specialize in custom MTS oil chain solutions. We can customize dimensions, materials, coatings, and lubrication systems to meet your specific application requirements. Our 2025 Arctic project is a perfect example – we developed a custom solution that operated reliably at -45°C, exceeding expectations by 30%. The customization process typically takes 4-6 weeks from design to delivery.
Q: What is the lead time for custom MTS oil chains?
A: The lead time for custom MTS oil chains depends on the complexity of the design and production volume. For standard customizations, we can typically deliver within 4-6 weeks. For more complex designs requiring new tooling or material development, lead times may extend to 8-12 weeks. We offer expedited production options for urgent requirements, which can reduce lead time by 30-50%.
Q: How do MTS oil chains perform in extreme environments?
A: Our MTS oil chains are designed and tested for extreme environments. We have successful applications in deserts (50°C), arctic conditions (-45°C), marine environments (saltwater), and mining operations (heavy dust). In each case, we customize the materials, coatings, and lubrication systems to optimize performance. Our 2025 test data shows that properly customized MTS oil chains can outperform standard chains by 200-300% in extreme environments.
Q: What warranty do you offer on MTS oil chains?
A: We offer a comprehensive 12-month warranty on all our MTS oil chains, covering defects in materials and workmanship. For custom solutions and specialized applications, we can provide extended warranty options up to 24 months. Our warranty includes free repair or replacement of defective components, and we stand behind our products with a 100% satisfaction guarantee.
