Cold Formed Eccentric Locking Shaft Carbon Steel Stainless Steel Smart Locks Window Hardware Custom OEM / ODM
Cold Formed Eccentric Locking Shaft Carbon Steel & Stainless Steel Smart Locks & Window Hardware Custom OEM/ODM
Precision Eccentric Locking Shafts for Smart Locks & Sliding Windows
We manufacture high-performance cold-formed eccentric locking shafts designed for smart locks and thermal break sliding windows, ensuring secure and smooth operation. Made from carbon steel (high strength) or stainless steel (corrosion-resistant), our shafts feature precise eccentricity for reliable locking mechanisms. We support full customization based on your drawings or samples, ensuring perfect compatibility with your hardware systems.
✅ Key Features:
✔ Optimized for Smart Locks & Windows – Ensures smooth engagement and long-term durability.
✔ Cold Forming Technology – Enhances mechanical strength (+25% vs. machined shafts).
✔ Corrosion-Resistant Options – Stainless steel (304/316) for outdoor & humid environments.
✔ Custom Eccentricity & Dimensions – Tailored to fit your lock or window mechanism.
✔ Fast Prototyping – Samples ready in 10-15 days after drawing approval.
