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
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.
