Titanium Main Pivot Axle is a lightweight fullsuspension main pivot component engineered for Full-suspension main pivot hollow axle 15mm OD. Forged and CNC machined from Grade 5 Ti-6Al-4V, it achieves 40-45% weight savings versus steel while maintaining the fatigue life required for demanding cycling applications. Threaded interfaces are designed to prevent galling in outdoor environments.

Q: Does Titanium Main Pivot Axle require special assembly or anti-seize? ▼
Yes. Titanium-to-titanium threaded interfaces on Titanium Main Pivot Axle are susceptible to galling (cold welding) during assembly. Application of MoS₂ or copper-based anti-seize compound to all threaded contact surfaces is mandatory. Lubricated installation torque values are typically 15-20% lower than dry values. Thread engagement should not exceed 3× thread diameter.
Q: What is the typical lead time for Titanium Main Pivot Axle orders? ▼
Standard lead time for Titanium Main Pivot Axle is 15-25 business days depending on quantity and complexity. Rush orders (3-5 working days) are available for prototype evaluation. Sample evaluation (1-5 units) can be expedited to 5-7 business days. Volume pricing is available for production quantities above 100 units.
Q: What material certifications are provided with Titanium Main Pivot Axle? ▼
Each Titanium Main Pivot Axle shipment includes EN 10204 Type 3.1 mill test certificate with chemical analysis, mechanical properties, and heat identification. Dimensional inspection reports and Certificate of Conformance (CoC) are standard. First Article Inspection Reports (FAIR) per AS9102 are available on request for fullsuspension main pivot.
