A conventional roller chain is fully flexible in both directions &#8211; 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<p style=\"font-size: clamp(14px,1.6vw,16px);\">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 &#8211; 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<p style=\"font-size: clamp(14px,1.6vw,16px);\">The primary application of EP anti-backbend push chains is in window actuator systems &#8211; 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<p style=\"font-size: clamp(14px,1.6vw,16px);\">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 &#8211; 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<p>&nbsp;<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-212\" src=\"https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/Anti-backbend-chains-for-pushing-window-1.webp\" alt=\"Cadenas anti-flexi\u00f3n-hacia-atr\u00e1s-para-empujar-ventana-1\" width=\"600\" height=\"600\" srcset=\"https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/Anti-backbend-chains-for-pushing-window-1.webp 600w, https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/Anti-backbend-chains-for-pushing-window-1-480x480.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 600px, 100vw\" \/><\/p>\n<\/div>\n<\/div>\n<div style=\"background: #f4f7fb; border-radius: 8px; padding: 20px 4%; margin-bottom: 36px;\">\n<p style=\"font-size: clamp(12px,1.4vw,14px); color: #475569; margin: 0;\"><strong>Clave de dimensi\u00f3n:<\/strong> P = Paso (mm) | d1 m\u00e1x = Di\u00e1metro m\u00e1ximo del rodillo (cadena de bujes: di\u00e1metro exterior del buje) | b1 m\u00edn = Ancho interior entre placas m\u00edn | d2 m\u00e1x = Di\u00e1metro m\u00e1ximo del pasador | L m\u00e1x = Longitud m\u00e1xima del pasador | H m\u00e1x = Altura m\u00e1xima total de la placa (perfil exterior de la placa anti-flexi\u00f3n) | h m\u00e1x = Profundidad m\u00e1xima de la placa est\u00e1ndar | t\/T m\u00e1x = Espesor m\u00e1ximo de la placa interior\/exterior | Q m\u00edn = Resistencia a la tracci\u00f3n m\u00ednima kN\/lbf | q = Peso kg\/m | * = Cadena de bujes (d1 es el di\u00e1metro exterior del buje)<\/p>\n<\/div>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; border-radius: 6px; box-shadow: 0 3px 12px rgba(13,27,46,0.15); display: block; margin-bottom: 16px;\" title=\"Gama de productos de cadenas anti-flexi\u00f3n EP\" src=\"https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/types-of-chain-1.webp\" alt=\"Cadena de empuje anti-doblamiento Ever-Power para actuador de ventana, series EP-06BF y EP-08BF\" \/><\/p>\n<h2 style=\"color: #0d1b2e; font-size: clamp(20px,2.6vw,28px); border-bottom: 3px solid #e8a020; padding-bottom: 10px; margin-top: 0;\">Especificaciones de la cadena de empuje anti-flexi\u00f3n<\/h2>\n<p style=\"font-size: clamp(13px,1.5vw,15px); color: #475569; margin-bottom: 16px;\">Todas las dimensiones en mm.

The d1 dimension for these models is the external diameter of the bush, not an outer roller.

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 &#8211; the motor pushes the chain &#8211; 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<details style=\"margin-bottom: 16px; border: 1px solid #dde6f2; border-radius: 6px; overflow: hidden;\">\n<summary style=\"background: #f4f7fb; padding: 14px 18px; font-size: clamp(14px,1.6vw,16px); font-weight: bold; color: #0d1b2e; cursor: pointer; list-style: none;\">\u00bfQu\u00e9 dimensiones de canal gu\u00eda necesito para una cadena espec\u00edfica?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">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 &#8211; any bow in the channel will cause the chain to bind under compressive load.<\/div>\n<\/details>\n<details style=\"margin-bottom: 16px; border: 1px solid #dde6f2; border-radius: 6px; overflow: hidden;\">\n<summary style=\"background: #f4f7fb; padding: 14px 18px; font-size: clamp(14px,1.6vw,16px); font-weight: bold; color: #0d1b2e; cursor: pointer; list-style: none;\">\u00bfCu\u00e1l es la fuerza de empuje m\u00e1xima que puede transmitir una cadena determinada?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">La fuerza de empuje m\u00e1xima est\u00e1 limitada por la resistencia al pandeo de la columna del sistema de cadena en gu\u00eda, no por la resistencia a la tracci\u00f3n de la cadena. La resistencia de la columna depende de la longitud sin soporte de la cadena entre el punto de salida de la gu\u00eda y el punto de carga (el marco de la ventana), la rigidez de la secci\u00f3n transversal de la cadena y las condiciones de los extremos. Para la mayor\u00eda de las aplicaciones de actuadores de ventanas, la longitud sin soporte es muy corta (menos de 50 mm) y la salida de la gu\u00eda est\u00e1 cerca del marco de la ventana, por lo que la resistencia de la columna es muy alta en relaci\u00f3n con la fuerza de empuje requerida. Si la longitud sin soporte es mayor, se debe utilizar una cadena con una dimensi\u00f3n H mayor (perfil de placa m\u00e1s alto), ya que tiene mayor rigidez de secci\u00f3n. Comun\u00edquese con EP con la geometr\u00eda de su actuador y la fuerza de empuje requerida para obtener una recomendaci\u00f3n.<\/div>\n<\/details>\n<details style=\"margin-bottom: 16px; border: 1px solid #dde6f2; border-radius: 6px; overflow: hidden;\">\n<summary style=\"background: #f4f7fb; padding: 14px 18px; font-size: clamp(14px,1.6vw,16px); font-weight: bold; color: #0d1b2e; cursor: pointer; list-style: none;\">\u00bfPueden las cadenas de suministro de EP cumplir con las especificaciones de los fabricantes de equipos originales (OEM) de actuadores existentes?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">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 &#8211; minimum order for custom configurations is typically 200 metres.<\/div>\n<\/details>\n<details style=\"margin-bottom: 16px; border: 1px solid #dde6f2; border-radius: 6px; overflow: hidden;\">\n<summary style=\"background: #f4f7fb; padding: 14px 18px; font-size: clamp(14px,1.6vw,16px); font-weight: bold; color: #0d1b2e; cursor: pointer; list-style: none;\">\u00bfCu\u00e1l es la diferencia entre EP-08BF20 y EP-08BF208?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">Tanto el EP-08BF20 como el EP-08BF208 comparten el mismo paso (12,700 mm), di\u00e1metro del rodillo (8,51 mm), ancho interior (7,75 mm), di\u00e1metro del pasador (4,45 mm) y altura de la placa. La diferencia radica en la resistencia m\u00ednima a la tracci\u00f3n: el EP-08BF20 tiene una clasificaci\u00f3n de 18,0 kN\/4046 lbf y el EP-08BF208 de 10,0 kN\/2248 lbf. Esto refleja una diferencia en el espesor o el tratamiento del material de la placa entre ambos modelos. El EP-08BF208 est\u00e1 especificado para aplicaciones de carga menor o para actuadores cuyo dise\u00f1o original utiliza una placa m\u00e1s ligera. El EP-08BF20 es la opci\u00f3n de mayor resistencia para aplicaciones que requieren una mayor capacidad de fuerza de empuje y tracci\u00f3n. La longitud del pasador del EP-08BF208 (17,00 mm) tambi\u00e9n es ligeramente mayor que la del EP-08BF20 (16,70 mm), lo que afecta al dimensionamiento del ancho del canal gu\u00eda.<\/div>\n<\/details>\n<details style=\"margin-bottom: 4px; border: 1px solid #dde6f2; border-radius: 6px; overflow: hidden;\">\n<summary style=\"background: #f4f7fb; padding: 14px 18px; font-size: clamp(14px,1.6vw,16px); font-weight: bold; color: #0d1b2e; cursor: pointer; list-style: none;\">\u00bfQu\u00e9 longitud debo pedir y c\u00f3mo se guarda la cadena?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">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 &#8211; 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 &#8211; 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<h2 style=\"color: #0d1b2e; font-size: clamp(20px,2.6vw,28px); border-bottom: 3px solid #e8a020; padding-bottom: 10px; margin-top: 40px;\">Lo que dicen nuestros clientes<\/h2>\n<div style=\"display: grid; grid-template-columns: repeat(auto-fill, minmax(260px, 1fr)); gap: 16px; margin: 20px 0 40px;\">\n<div style=\"background: #ffffff; border-radius: 6px; padding: 22px; box-shadow: 0 2px 8px rgba(13,27,46,0.08); border-top: 3px solid #e8a020;\">\n<p style=\"color: #e8a020; font-size: 16px; margin: 0 0 10px;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"font-size: clamp(12px,1.4vw,14px); color: #334155; line-height: 1.7; margin: 0 0 14px; font-style: italic;\">&#8220;We manufacture electric window actuators for commercial and institutional buildings.
