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=\"Anti-achteroverbuigingskettingen voor het openen van ramen 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>Dimensielegenda:<\/strong> P = Steek (mm) | d1 max = Maximale roldiameter (busketting: buitendiameter bus) | b1 min = Minimale binnenbreedte tussen platen | d2 max = Maximale pendiameter | L max = Maximale penlengte | H max = Maximale totale plaathoogte (buitenste anti-terugbuigingsplaatprofiel) | h max = Maximale standaard plaatdiepte | t\/T max = Maximale binnen-\/buitenplaatdikte | Q min = Minimale treksterkte kN\/lbf | q = Gewicht kg\/m | * = Busketting (d1 is de buitendiameter van de bus)<\/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=\"EP anti-terugbuigingsketting productassortiment\" src=\"https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/types-of-chain-1.webp\" alt=\"Ever-Power anti-terugbuiging duwketting voor raamaandrijving EP-06BF EP-08BF serie\" \/><\/p>\n<h2 style=\"color: #0d1b2e; font-size: clamp(20px,2.6vw,28px); border-bottom: 3px solid #e8a020; padding-bottom: 10px; margin-top: 0;\">Specificaties van de anti-terugbuigingsduwketting<\/h2>\n<p style=\"font-size: clamp(13px,1.5vw,15px); color: #475569; margin-bottom: 16px;\">Alle afmetingen in mm.

The chain is fully rigid in the push direction and normally flexible in the pull direction. This dual behaviour &#8211; rigid rod when pushed, flexible chain when pulled &#8211; 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<div style=\"background: rgba(255,255,255,0.06); border-left: 4px solid #e8a020; padding: 18px 16px; border-radius: 4px;\">\n<h3 style=\"color: #e8a020; font-size: clamp(13px,1.5vw,15px); margin: 0 0 8px; font-weight: bold;\">Compact opbergen in ingetrokken positie<\/h3>\n<p style=\"color: #a8bdd4; font-size: clamp(12px,1.4vw,13px); line-height: 1.65; margin: 0;\">Wanneer de raamaandrijving de ketting intrekt, hervat de normale kettingbeweging en vouwt de ketting zich compact op in het magazijn of opbergkanaal van de aandrijving achter het aandrijftandwiel. De behuizing van de aandrijving kan aanzienlijk korter zijn dan de maximale openingsslag van het raam, omdat de ketting in opgevouwen toestand wordt opgeborgen in plaats van uitgeschoven te blijven. De EP-06BF34 met een steek van 9,525 mm en de EP-08BF6 met een steek van 12,700 mm zijn de meest voorkomende maten voor compacte raamaandrijvingen in woningen en lichte commerci\u00eble gebouwen.<\/p>\n<\/div>\n<div style=\"background: rgba(255,255,255,0.06); border-left: 4px solid #e8a020; padding: 18px 16px; border-radius: 4px;\">\n<h3 style=\"color: #e8a020; font-size: clamp(13px,1.5vw,15px); margin: 0 0 8px; font-weight: bold;\">Compatibiliteit van geleidingskanalen en buizen<\/h3>\n<p style=\"color: #a8bdd4; font-size: clamp(12px,1.4vw,13px); line-height: 1.65; margin: 0;\">EP-anti-terugbuigingskettingen zijn ontworpen om te functioneren in een geleidingskanaal of -buis die de ketting over de gehele lengte ondersteunt en zo zijdelingse knik onder hoge drukbelastingen voorkomt. De afmetingen H en h in de specificatietabel zijn de belangrijkste parameters voor het bepalen van de doorsnede van het geleidingskanaal. H geeft de totale kettinghoogte inclusief de verlenging van de anti-terugbuigingsplaat, en h geeft de binnendiepte van de plaat. De boring van het geleidingskanaal moet vrij zijn van H op de kettinghoogte-as en b1 (plus penuitsteeksel) op de kettingbreedte-as om een \u200b\u200bsoepele beweging zonder vastlopen mogelijk te maken.<\/p>\n<\/div>\n<div style=\"background: rgba(255,255,255,0.06); border-left: 4px solid #e8a020; padding: 18px 16px; border-radius: 4px;\">\n<h3 style=\"color: #e8a020; font-size: clamp(13px,1.5vw,15px); margin: 0 0 8px; font-weight: bold;\">Bush Chain-varianten<\/h3>\n<p style=\"color: #a8bdd4; font-size: clamp(12px,1.4vw,13px); line-height: 1.65; margin: 0;\">Models marked * &#8211; EP-*06CF22, EP-*06CF30, and EP-*P9.525F1 &#8211; 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<div style=\"background: rgba(255,255,255,0.06); border-left: 4px solid #e8a020; padding: 18px 16px; border-radius: 4px;\">\n<h3 style=\"color: #e8a020; font-size: clamp(13px,1.5vw,15px); margin: 0 0 8px; font-weight: bold;\">Low Maintenance &#8211; Low Cycle Application<\/h3>\n<p style=\"color: #a8bdd4; font-size: clamp(12px,1.4vw,13px); line-height: 1.65; margin: 0;\">Window actuator push chains operate at very low cycle rates &#8211; typically 1 to 10 open-close operations per day &#8211; and at very low speeds (0.01 to 0.1 m\/s chain speed).

De actuator wordt doorgaans aan de scharnierzijde van het dakraam gemonteerd en de ketting duwt langs het frameprofiel om het glaspaneel te openen, tegen de zwaartekracht en winddruk in.

Bij rookafzuiginstallaties moet de actuator de ventilatieopening onder normale omstandigheden betrouwbaar gesloten houden tegen winddruk, en deze vervolgens snel openen en volledig openhouden tegen windbelasting tijdens een brand. De anti-terugbuigingsvergrendeling zorgt voor de structurele stijfheid die nodig is om de open positie te behouden onder zijdelingse windbelasting, zonder dat een apart mechanisch vasthoudmechanisme nodig is.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; max-width: 370px; padding: 20px; background: #ffffff; border-left: 4px solid #1a6db5; border-radius: 6px; box-shadow: 0 2px 8px rgba(13,27,46,0.07);\">\n<h3 style=\"color: #0d1b2e; margin-top: 0; font-size: clamp(14px,1.7vw,17px);\">Industri\u00eble ventilatie- en lamellenactuatoren<\/h3>\n<p style=\"color: #334155; line-height: 1.7; font-size: clamp(12px,1.4vw,14px); margin-bottom: 0;\">De kettingen EP-08BF20, EP-P12.7F4 en EP-16AF101 zijn geschikt voor aandrijvingen van ventilatielamellen in industri\u00eble gebouwen, ventilatiepanelen in agrarische gebouwen, nokventilatie-openers voor kassen en gemotoriseerde ramen van groot formaat in fabrieken en magazijnen.

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;\">Welke afmetingen van de geleiderkanalen heb ik nodig voor een specifieke keten?<\/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;\">Wat is de maximale duwkracht die een bepaalde ketting kan overbrengen?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">De maximale duwkracht wordt beperkt door de kniksterkte van de kolom van het kettinggeleidingssysteem, niet door de treksterkte van de ketting. De kolomsterkte is afhankelijk van de onondersteunde lengte van de ketting tussen het uitgangspunt van de geleiding en het belastingspunt (het raamkozijn), de dwarsdoorsnedestijfheid van de ketting en de randvoorwaarden. Voor de meeste raamactuatoren is de onondersteunde lengte zeer kort (minder dan 50 mm) en bevindt het uitgangspunt van de geleiding zich dicht bij het raamkozijn, waardoor de kolomsterkte zeer hoog is ten opzichte van de benodigde duwkracht. Als de onondersteunde lengte langer is, moet een ketting met een grotere H-maat (hoger plaatprofiel) worden gebruikt, omdat deze een grotere dwarsdoorsnedestijfheid heeft.

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;\">Wat is het verschil tussen EP-08BF20 en EP-08BF208?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">Zowel de EP-08BF20 als de EP-08BF208 hebben dezelfde steek (12,700 mm), roldiameter (8,51 mm), binnenbreedte (7,75 mm), pendiameter (4,45 mm) en plaathoogte. Het verschil zit hem in de minimale treksterkte: de EP-08BF20 heeft een nominale treksterkte van 18,0 kN\/4046 lbf en de EP-08BF208 een nominale treksterkte van 10,0 kN\/2248 lbf. Dit verschil is te wijten aan een verschil in plaatdikte of materiaalbehandeling tussen de twee modellen. De EP-08BF208 is geschikt voor toepassingen met een lagere belasting of voor actuatoren waarbij het oorspronkelijke ontwerp een lichtere plaatspecificatie gebruikt. De EP-08BF20 is de sterkere variant voor toepassingen die een grotere duw- en trekkracht vereisen. De pinlengte van EP-08BF208 (17,00 mm) is ook iets langer dan die van EP-08BF20 (16,70 mm), wat van invloed is op de dimensionering van de geleidingskanaalbreedte.<\/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;\">Welke lengte moet ik bestellen en hoe wordt de ketting opgeborgen?<\/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;\">Wat onze klanten zeggen<\/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.
