Product Overview<\/h2>\n<\/div>\n

The P11.5SS anti-sidebow push chain is a precision-engineered window actuation chain designed for motorised sliding windows and outward-opening window panels. With an 11.5 mm pitch and a minimum tensile strength of 5.5 kN, it delivers reliable linear actuation along curved or straight guide channels \u2014 driven by an electric motor or hydraulic cylinder.<\/p>\n

Unlike standard roller chains, the P11.5SS is engineered to transmit compressive<\/em> push forces through a curved path without lateral buckling. The chain is manufactured from high-quality alloy steel and finished with a zinc\u2013nickel alloy electroplated coating, combining corrosion resistance with long-term dimensional stability \u2014 critical requirements for window systems exposed to outdoor humidity, condensation, and temperature cycling.<\/p>\n<\/div>\n

Note:<\/strong> All dimensions in millimetres. Q min = minimum ultimate tensile strength under static load per ISO test method.

How Anti-sidebow Technology Works<\/h2>\n<\/div>\n

The defining engineering feature of this chain is its bidirectional lateral-flex capability<\/strong>. The chain body is split into two sub-assemblies that articulate independently around two orthogonal axes \u2014 enabling controlled push through curved guide channels while resisting unintended buckling.<\/p>\n

<\/p>\n

\n
\n
\n

Inner Chain Plates<\/p>\n<\/div>\n

\n

High-strength alloy steel<\/strong> construction. Carries the tensile and compressive load along the chain axis. Profiled grooves on inner plates receive aligning protrusions from the outer links, preventing uncontrolled lateral collapse under push load.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Outer Chain Links<\/p>\n<\/div>\n

\n

Engineered plastic<\/strong> composition. Reduces overall chain weight, eliminates metal-to-metal contact noise during lateral bending, and allows the link body to flex slightly for smooth guide-channel tracking without binding.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Pivot Pins & Bolts<\/p>\n<\/div>\n

\n

\u0421\u0442\u0430\u043b\u044c<\/strong> pivot pin and locking bolt. Connects inner plates to outer links through lateral pivot holes defined by separate support plates. Extended pin-to-bushing clearance enables lateral articulation to a minimum radius of 250 mm<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

\n

Load Rating Note<\/p>\n

Due to the extended pin-bushing clearance required for lateral flex, the P11.5SS is rated for lower load levels<\/strong> than equivalent rigid roller chains of the same pitch. It is designed for window actuation forces \u2014 not for heavy conveyor or power-transmission duties. Contact our engineering team if working load requirements are near the rated tensile strength.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Sprocket Compatibility<\/h2>\n<\/div>\n

The P11.5SS requires sprockets specifically dimensioned for the anti-sidebow link geometry \u2014 standard P11.5 sprockets for rigid roller chains are not interchangeable, as the lateral envelope of the anti-sidebow outer links requires wider tooth-space clearance.<\/p>\n

Zinc\u2013Nickel Anti-corrosion Coating<\/h2>\n<\/div>\n

All P11.5SS chains are finished with a Zn\u2013Ni alloy electroplate<\/strong> at approximately 85:15 zinc-to-nickel ratio. This formulation shifts the galvanic protection potential relative to standard zinc, delivering substantially better salt-spray performance:<\/p>\n
