304 Stainless Steel Sliding Hinge
,12-inch Extended Arms Sliding Hinge
,Four-Link Mechanism Sliding Hinge
This extended-length, heavy-duty friction stay is specifically designed for large-size casement windows. It is precision-stamped from 3.0mm-thick 304 stainless steel sheet, The 12-inch extended arms are designed to fit standard 22mm door and window profile grooves. The four-link mechanism offers strong load-bearing capacity and smooth opening and closing motion, along with excellent corrosion and rust resistance, making it an essential load-bearing hardware component for large-sized thermal break aluminum casement windows and heavy-duty outward-opening windows.
Thickened 304 Stainless Steel Base Material, Outstanding Heavy-Duty Corrosion Resistance
The entire hinge is precision-stamped from a single piece of SUS304 stainless steel sheet with a thickness of 3.0 mm. Compared to conventional thin-profile products, this design significantly enhances structural rigidity and load-bearing capacity, enabling it to stably support large-sized, heavy window sashes. It resists bending and deformation even under long-term exposure to the sash’s own weight and wind loads, delivering superior wind and pressure resistance.
304 stainless steel inherently possesses excellent corrosion and rust resistance. Verified through a 500-hour salt spray test, it ensures long-lasting performance in environments such as coastal areas with high humidity, outdoor exposure to sun and rain, and damp conditions in kitchens and bathrooms, without issues like rust, jamming, oxidation, or wear. All hinge joints are precision-riveted with solid rivets, ensuring a tight fit with no play and smooth, low-noise operation. The product complies with the QB/T 5338-2018 General Technical Standard for Door and Window Hardware and has passed a 100,000-cycle durability test for repeated opening and closing. It maintains stable performance even with frequent use over many years, ensuring a longer service life.
Extended Four-Bar Linkage Structure: Stable Support and Smooth Operation
Featuring a 12-inch (approx. 305 mm) extended arm design paired with a classic four-bar linkage transmission mechanism, the window sash experiences even force distribution during opening, resulting in a smooth and stable opening and closing trajectory without jamming, wobbling, or shaking; When open, the overall structure forms a stable triangular mechanical support that firmly locks the sash at the desired opening angle, withstands strong wind impacts, and prevents the sash from swaying and colliding with the window frame. It also limits the maximum opening angle, balancing ventilation effectiveness with home safety.
The slider ends are equipped with wear-resistant guide and stop components, ensuring uniform sliding resistance and a smooth, effortless feel when operating the window. The end stops are reliable and precise, effectively enhancing the smoothness of window operation and the overall user experience.
Standard groove dimensions ensure easy installation and strong compatibility
Compatible with 22mm-wide standard door and window profile grooves, this is a universal specification for large-size thermal-break aluminum casement windows, heavy-duty exterior casement windows, and top-hung windows. The base features industry-standard mounting holes for precise alignment, allowing for quick assembly using standard screws. No additional cutting or grooving of the profiles is required, making batch assembly at door and window factories efficient and time-saving, while also facilitating convenient replacement during home renovation and after-sales maintenance.
Wide Applicability Across Multiple Scenarios
Widely compatible with large-size exterior casement windows, heavy-duty thermal-break aluminum floor-to-ceiling windows, large-size balcony casement windows, and heavy-duty top-hung windows for sunrooms; suitable for residential large-window hardware systems, high-end finishing projects for real estate developments, load-bearing performance upgrades for older windows and doors, as well as bulk export supply of window and door hardware.
