Anti-Backbend Push Chain – Product Overview<\/h2>\n
\n
\n

V\u011b\u010dn\u00e1 s\u00edla \u0159et\u011bzy proti oh\u00fdb\u00e1n\u00ed pro zatla\u010den\u00ed okna<\/a> are a specialised family of roller chains designed to transmit both push and pull forces along the chain axis without buckling. A conventional roller chain is fully flexible in both directions – it can be pulled under tension but will buckle immediately if a compressive (push) force is applied. An anti-backbend chain is engineered with extended outer link plates and an interlocking plate geometry that prevents the chain from bending backward beyond the straight position, effectively turning the chain into a rigid push rod when loaded in compression while retaining normal articulation in the pulling direction.<\/p>\n

The anti-backbend function is achieved through the plate geometry. The outer link plates in the EP push chain range are formed with a stepped or extended profile that bears against the adjacent inner link plates when the chain is in the straight (tensioned or compressed) configuration. This contact between plates prevents back-articulation – the chain cannot bend in the direction that would be compressive buckling. As the chain is fed out from the sprocket in the push direction, the interlocked plates form a rigid column capable of transmitting the compressive load through the chain length to the driven component. When the chain is retracted, the plates separate and the chain becomes fully flexible again, allowing it to coil or store in a compact magazine behind the sprocket.<\/p>\n

The primary application of EP anti-backbend push chains is in window actuator systems – automatic openers for roof lights, skylights, clerestory windows, industrial ventilation louvres, smoke control ventilators, and architectural glazing systems. In these applications, the window actuator motor drives a sprocket that feeds the chain out through a guide tube to push the window open, then retracts the chain to pull the window closed. The chain must be rigid enough in the push direction to push the window open against its own weight, wind pressure, and any sealing resistance, while flexible enough in the pull direction to store compactly in the actuator housing.<\/p>\n

The EP range covers nine models from EP-06BF34 at 9.525 mm pitch through EP-16AF101 at 25.400 mm pitch. Models marked with an asterisk (*) are bush chains – the d1 dimension in the specification table is the external diameter of the bush rather than an outer roller. The H and h dimensions in the specification table describe the outer link plate profile: H is the overall plate height (including the anti-backbend extension plate) and h is the standard plate depth within the chain height, both of which affect the guide tube or channel dimensions required to support the chain in service.<\/p>\n

Anti-Backbend Push Chain – Key Technical Features<\/h2>\n
\n
\n

Geometrie desky proti ohybu<\/h3>\n

The extended outer link plates bear against adjacent inner link plates when the chain is in the straight configuration, blocking back-articulation and preventing compressive buckling. The chain is fully rigid in the push direction and normally flexible in the pull direction. This dual behaviour – rigid rod when pushed, flexible chain when pulled – enables a single chain to both push a load open and pull it closed from the same actuator without a separate push mechanism.<\/p>\n<\/div>\n

Varianty \u0159et\u011bz\u016f pouzder<\/h3>\n

Models marked * – EP-*06CF22, EP-*06CF30, and EP-*P9.525F1 – are bush chain (sleeve chain) variants where no separate outer roller is fitted. The d1 dimension for these models is the external diameter of the bush, not an outer roller. Bush chain variants are lighter than roller chain equivalents at the same pitch and are used where roller wear from sprocket engagement is not a concern due to the low cycle count of typical window actuator applications. The absence of the outer roller also reduces the overall chain height slightly.<\/p>\n<\/div>\n

\n

Low Maintenance – Low Cycle Application<\/h3>\n

Window actuator push chains operate at very low cycle rates – typically 1 to 10 open-close operations per day – and at very low speeds (0.01 to 0.1 m\/s chain speed). These characteristics mean that lubrication requirements are minimal and chain wear is negligible under normal operating conditions. The EP push chain range is supplied pre-lubricated and requires no additional lubrication for normal building ventilation applications. For industrial applications with higher cycle rates, periodic light mineral oil application to the joint areas is recommended.<\/p>\n<\/div>\n

\n

Mo\u017enosti odoln\u00e9 proti korozi<\/h3>\n

Window actuator chains are frequently installed in humid, coastal, or chemically challenging environments – pool enclosures, conservatories, marine buildings, and industrial facilities with chemical atmospheres. EP push chains in the 06BF and 08BF series are available in stainless steel (SUS304 or SUS316L) on request for these environments. Nickel-plated carbon steel variants are also available for moderate corrosion resistance at lower cost. Please specify the required surface treatment or material grade when requesting a quotation.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

A standard roller chain buckles immediately under any compressive load because the joints are free to articulate in both directions. An anti-backbend chain is prevented from bending in the reverse (back) direction by the geometry of the outer link plates, which are extended or stepped so that they physically bear against the inner link plates at the straight configuration. When a compressive load is applied – the motor pushes the chain – the chain cannot bend backward and instead transmits the compressive force along the chain length as a rigid column. The guide channel or tube surrounding the chain provides lateral support to prevent the chain from buckling sideways under load, completing the push force transmission path to the driven window or louvre.<\/div>\n<\/details>\n

The guide channel cross-section must clear the full chain profile. The minimum channel height clearance is the H max dimension from the specification table plus 0.5 mm running clearance on each side (H max + 1.0 mm total height). The minimum channel width clearance is the pin length L max plus 0.5 mm running clearance on each side (L max + 1.0 mm total width). For example, EP-08BF6 has H max 17.00 mm and L max 16.60 mm, requiring a channel of at least 18.0 mm height by 17.6 mm width. For applications with significant chain speed or vibration, increase the clearance to 1.0 mm on each side. The channel must be smooth-bore on the inner surfaces and straight along the push axis – any bow in the channel will cause the chain to bind under compressive load.<\/div>\n<\/details>\n

Yes. The models in the specification table cover the most widely used anti-backbend chain specifications in the window actuator industry. For actuators from major OEM manufacturers such as Sommer, Geze, Tormax, Raico, and others, please supply the existing chain designation or a chain sample so EP can verify the dimensional match. Key dimensions to verify are pitch, roller or bush diameter, inner width (b1), pin diameter (d2), pin length (L), and overall plate height (H). EP can also produce custom anti-backbend chain configurations outside the standard table if the required quantity justifies a tooling investment – minimum order for custom configurations is typically 200 metres.<\/div>\n<\/details>\n

The required chain length is the full push stroke of the actuator plus the storage length in the magazine plus the wrap around the drive sprocket plus a short tail for the chain anchor point. In practice, the actuator manufacturer specifies the chain length for their product as part of the system design – for OEM actuator replacement chains, simply order the length specified in the actuator service documentation. For new actuator designs, add approximately 20% to the maximum opening stroke to allow for sprocket wrap and storage tail. The chain stores in the magazine by normal chain articulation – the retracted chain folds back on itself at the sprocket exit with a bend radius equal to approximately 3 to 4 times the chain pitch, so the magazine depth must be at least this distance from the sprocket centreline.<\/div>\n<\/details>\n<\/div>\n
