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

Ever-Power Correntes anti-flex\u00e3o para empurrar janelas<\/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

Geometria da placa anti-flex\u00e3o<\/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

\n

Armazenamento compacto na posi\u00e7\u00e3o retra\u00edda<\/h3>\n

Quando o atuador da janela recolhe a corrente, a articula\u00e7\u00e3o normal da corrente \u00e9 retomada e a corrente se dobra de forma compacta no compartimento do atuador ou no canal de armazenamento atr\u00e1s da roda dentada de acionamento. A carca\u00e7a do atuador pode ser significativamente mais curta do que o curso m\u00e1ximo de abertura da janela, porque a corrente \u00e9 armazenada dobrada em vez de permanecer estendida. Os modelos EP-06BF34 com passo de 9,525 mm e EP-08BF6 com passo de 12,700 mm s\u00e3o os tamanhos mais comuns para atuadores de janelas residenciais e comerciais de pequeno porte.<\/p>\n<\/div>\n

\n

Compatibilidade do canal guia e do tubo<\/h3>\n

As correntes anti-flex\u00e3o EP s\u00e3o projetadas para operar dentro de um canal ou tubo guia que suporta a corrente ao longo de seu comprimento de empuxo, evitando flambagem lateral sob altas cargas de compress\u00e3o. As dimens\u00f5es H e h na tabela de especifica\u00e7\u00f5es s\u00e3o os par\u00e2metros-chave para dimensionar a se\u00e7\u00e3o transversal do canal guia. H indica a altura total da corrente, incluindo a extens\u00e3o da placa anti-flex\u00e3o, e h indica a profundidade interna da placa. O furo do canal guia deve ter folga suficiente em rela\u00e7\u00e3o a H no eixo da altura da corrente e b1 (mais a protrus\u00e3o do pino) no eixo da largura da corrente para permitir um deslocamento suave sem travamento.<\/p>\n<\/div>\n

\n

Variantes de corrente Bush<\/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

Op\u00e7\u00f5es resistentes \u00e0 corros\u00e3o<\/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

O atuador \u00e9 normalmente montado na extremidade da dobradi\u00e7a da claraboia, e a corrente empurra ao longo do perfil da estrutura para abrir o painel envidra\u00e7ado, vencendo a gravidade e a press\u00e3o do vento. O armazenamento compacto da corrente retra\u00edda, quando dobrada, permite o uso de alojamentos de atuadores mais finos, adequados aos perfis estreitos dos sistemas de claraboias modernos.<\/p>\n<\/div>\n

Sistemas de ventila\u00e7\u00e3o de fuma\u00e7a e seguran\u00e7a contra inc\u00eandio<\/h3>\n

Os ventiladores autom\u00e1ticos de fuma\u00e7a e os sistemas de abertura de ventila\u00e7\u00e3o acionados por inc\u00eandio utilizam correntes de acionamento EP das s\u00e9ries 08BF e P12.7F devido \u00e0 sua maior resist\u00eancia \u00e0 tra\u00e7\u00e3o e capacidade de for\u00e7a de acionamento. Em aplica\u00e7\u00f5es de ventila\u00e7\u00e3o de fuma\u00e7a, o atuador deve manter a ventila\u00e7\u00e3o fechada de forma confi\u00e1vel contra a a\u00e7\u00e3o do vento em condi\u00e7\u00f5es normais e, em seguida, abri-la rapidamente e mant\u00ea-la totalmente aberta contra a carga do vento durante um inc\u00eandio. A geometria de travamento anti-retorno proporciona a rigidez estrutural necess\u00e1ria para manter a posi\u00e7\u00e3o aberta sob carga lateral do vento, sem a necessidade de um dispositivo mec\u00e2nico de reten\u00e7\u00e3o separado.<\/p>\n<\/div>\n

Perguntas frequentes<\/h2>\n
\n
\nComo uma corrente anti-flex\u00e3o transmite uma for\u00e7a de empuxo sem sofrer flambagem?<\/summary>\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
\nQuais as dimens\u00f5es necess\u00e1rias do canal guia para uma corrente espec\u00edfica?<\/summary>\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
\nQual \u00e9 a for\u00e7a m\u00e1xima de empuxo que uma determinada corrente pode transmitir?<\/summary>\n
A for\u00e7a m\u00e1xima de empuxo \u00e9 limitada pela resist\u00eancia \u00e0 flambagem da coluna do sistema de corrente-guia, e n\u00e3o pela resist\u00eancia \u00e0 tra\u00e7\u00e3o da corrente. A resist\u00eancia da coluna depende do comprimento da corrente sem suporte entre o ponto de sa\u00edda da guia e o ponto de aplica\u00e7\u00e3o da carga (a moldura da janela), da rigidez da se\u00e7\u00e3o transversal da corrente e das condi\u00e7\u00f5es de extremidade. Para a maioria das aplica\u00e7\u00f5es de atuadores de janelas, o comprimento sem suporte \u00e9 muito curto (menos de 50 mm) e a sa\u00edda da guia fica pr\u00f3xima \u00e0 moldura da janela, portanto, a resist\u00eancia da coluna \u00e9 muito alta em rela\u00e7\u00e3o \u00e0 for\u00e7a de empuxo necess\u00e1ria. Se o comprimento sem suporte for maior, deve-se usar uma corrente com uma dimens\u00e3o H maior (perfil de placa mais alto), pois ela possui maior rigidez da se\u00e7\u00e3o transversal. Entre em contato com a EP informando a geometria do seu atuador e a for\u00e7a de empuxo necess\u00e1ria para obter uma recomenda\u00e7\u00e3o.<\/div>\n<\/details>\n
\nSer\u00e1 que as cadeias de fornecimento da EP conseguem atender \u00e0s especifica\u00e7\u00f5es existentes dos fabricantes de equipamentos originais (OEMs) de atuadores?<\/summary>\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
\nQual a diferen\u00e7a entre EP-08BF20 e EP-08BF208?<\/summary>\n
Tanto o EP-08BF20 quanto o EP-08BF208 compartilham o mesmo passo (12,700 mm), di\u00e2metro do rolete (8,51 mm), largura interna (7,75 mm), di\u00e2metro do pino (4,45 mm) e altura da placa. A diferen\u00e7a reside na resist\u00eancia m\u00ednima \u00e0 tra\u00e7\u00e3o: o EP-08BF20 possui uma resist\u00eancia de 18,0 kN\/4046 lbf, enquanto o EP-08BF208 possui uma resist\u00eancia de 10,0 kN\/2248 lbf. Essa diferen\u00e7a reflete uma varia\u00e7\u00e3o na espessura ou no tratamento do material da placa entre os dois modelos. O EP-08BF208 \u00e9 especificado para aplica\u00e7\u00f5es com cargas menores ou para atuadores cujo projeto original utiliza uma placa mais leve. O EP-08BF20 \u00e9 a op\u00e7\u00e3o de maior resist\u00eancia para aplica\u00e7\u00f5es que exigem maior capacidade de for\u00e7a de tra\u00e7\u00e3o e compress\u00e3o. O comprimento do pino do EP-08BF208 (17,00 mm) tamb\u00e9m \u00e9 ligeiramente maior que o do EP-08BF20 (16,70 mm), o que influencia o dimensionamento da largura do canal guia.<\/div>\n<\/details>\n
\nQual o comprimento ideal da corrente que devo encomendar e como ela deve ser armazenada?<\/summary>\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

“EP-*06CF30 chains for our compact roof light actuators. The bush chain variant allows a slimmer guide channel than a roller chain equivalent, which is important for our slim-profile product line. EP verified the chain against our sample within 2 working days and delivered 500 metres of cut-to-length chains within the week. Exactly what we needed for a product launch deadline.”<\/p>\n
