<\/p>\n

Key features<\/p>\n

\n
\n
\u2194<\/span><\/div>\n

Lateral flexibility<\/p>\n

Pivots sideways around a second axis, enabling curved-track operation without binding or fatigue.<\/p>\n<\/div>\n

\n
\u21bb<\/span><\/div>\n

Min. curve radius 250 mm<\/p>\n

Designed for tight-radius guide tracks in push-type window openers and sliding panel actuators.<\/p>\n<\/div>\n

\n
\u2699<\/span><\/div>\n

Two-part link construction<\/p>\n

Steel pivot pin + engineered plastic inner link plates reduce noise and corrosion in service.<\/p>\n<\/div>\n

\n
\ud83d\udd17<\/span><\/div>\n

Standard attachments<\/p>\n

Accepts A1, A2, K1, K2, and extended-pin roller chain attachments for direct OEM integration.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

How it works<\/p>\n

\n
\n
\n

01 \u2014 Link design<\/p>\n

Inner link plates (plastic) and outer links (steel) are manufactured as separate components. A groove-and-protrusion geometry controls the lateral pivot angle precisely.<\/p>\n<\/div>\n

\n

02 \u2014 Dual-axis hinge<\/p>\n

Each hinge rotates about two axes: the standard in-plane articulation axis and a secondary lateral axis. Expanded pin\u2013bushing clearances allow smooth sideways deflection.<\/p>\n<\/div>\n

\n

03 \u2014 Load rating<\/p>\n

Reduced bearing area means lower working loads vs. a \u0440\u043e\u043b\u0438\u043a\u043e\u0432\u0430\u044f \u0446\u0435\u043f\u044c<\/a> of the same pitch. Apply a 7:1 safety factor for steady loads; increase for shock or dynamic conditions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

Compatible sprockets and drive components<\/p>\n

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\u2013bushing play. Available in carbon steel (plain or zinc-plated), case-hardened steel, and 304\/316 stainless steel for corrosive environments.<\/p>\n

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.<\/p>\n
