Dây xích chống cong vênh cho cửa sổ đẩy P12.75

Xích chống cong vênh dùng cho cửa sổ đẩy có thể chịu được các đường cong và uốn lượn. Loại xích này có nhiều tấm và phụ kiện đặc biệt. Do có diện tích chịu lực nhỏ, chúng phù hợp với tải trọng thấp hơn so với các loại xích con lăn tương tự. Hãy chọn loại phù hợp tại Ever-power dựa trên nhu cầu của bạn.

Key features

↔

Lateral flexibility

Pivots sideways around a second axis, enabling curved-track operation without binding or fatigue.

↻

Min. curve radius 250 mm

Designed for tight-radius guide tracks in push-type window openers and sliding panel actuators.

⚙

Two-part link construction

Steel pivot pin + engineered plastic inner link plates reduce noise and corrosion in service.

🔗

Standard attachments

Accepts A1, A2, K1, K2, and extended-pin roller chain attachments for direct OEM integration.

How it works

01 — Link design

Inner link plates (plastic) and outer links (steel) are manufactured as separate components. A groove-and-protrusion geometry controls the lateral pivot angle precisely.

02 — Dual-axis hinge

Each hinge rotates about two axes: the standard in-plane articulation axis and a secondary lateral axis. Expanded pin–bushing clearances allow smooth sideways deflection.

03 — Load rating

Reduced bearing area means lower working loads vs. a xích con lăn of the same pitch. Apply a 7:1 safety factor for steady loads; increase for shock or dynamic conditions.

Compatible sprockets and drive components

P12.75 anti-sidebow chains run with sprockets matched to the 12.75 mm pitch. Anti-sidebow sprockets use enlarged tooth clearances to accommodate expanded pin–bushing play. Available in carbon steel (plain or zinc-plated), case-hardened steel, and 304/316 stainless steel for corrosive environments.

Guide rails must be specified with a bend radius of at least 250 mm. Ever-Power supplies matched sprocket sets and provides engineering guidance on torque calculations, centre distance, and tensioner selection. Custom tooth counts and hub configurations are available for OEM applications.
