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-bagb\u00f8jningsk\u00e6der-til-at-skubbe-vindue-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>Dimensionsn\u00f8gle:<\/strong> P = Stigning (mm) | d1 maks = Rullediameter maks (b\u00f8sningsk\u00e6de: udvendig b\u00f8sningsdiameter) | b1 min = Indvendig bredde mellem pladerne min | d2 maks = Stiftdiameter maks | L maks = Stiftl\u00e6ngde maks | H maks = Samlet pladeh\u00f8jde maks (udvendig anti-bagb\u00f8jningspladeprofil) | h maks = Standard pladedybde maks | t\/T maks = Indvendig\/udvendig pladetykkelse maks | Q min = Min. tr\u00e6kstyrke kN\/lbf | q = V\u00e6gt kg\/m | * = B\u00f8sningsk\u00e6de (d1 er udvendig b\u00f8sningsdiameter)<\/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-backb\u00f8jningsk\u00e6de produktsortiment\" src=\"https:\/\/5speedtransmission.com\/wp-content\/uploads\/2026\/07\/types-of-chain-1.webp\" alt=\"Ever-Power anti-bagudb\u00f8jningsk\u00e6de til vinduesmotor EP-06BF EP-08BF-serien\" \/><\/p>\n<h2 style=\"color: #0d1b2e; font-size: clamp(20px,2.6vw,28px); border-bottom: 3px solid #e8a020; padding-bottom: 10px; margin-top: 0;\">Specifikationer for anti-bagudb\u00f8jningsk\u00e6de<\/h2>\n<p style=\"font-size: clamp(13px,1.5vw,15px); color: #475569; margin-bottom: 16px;\">Alle dimensioner er i mm.

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 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;\">Hvad er den maksimale trykkraft, som en given k\u00e6de kan overf\u00f8re?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">Den maksimale trykkraft er begr\u00e6nset af s\u00f8jlens bucklingstyrke i k\u00e6de-i-f\u00f8ringssystemet, ikke af k\u00e6dens tr\u00e6kstyrke. S\u00f8jlens styrke afh\u00e6nger af den uunderst\u00f8ttede l\u00e6ngde af k\u00e6den mellem f\u00f8ringens udgangspunkt og belastningspunktet (vinduesrammen), k\u00e6dens tv\u00e6rsnitsstivhed og slutforholdene. For de fleste vinduesaktuatorapplikationer er den uunderst\u00f8ttede l\u00e6ngde meget kort (mindre end 50 mm), og f\u00f8ringens udgang er t\u00e6t p\u00e5 vinduesrammen, s\u00e5 s\u00f8jlens styrke er meget h\u00f8j i forhold til den n\u00f8dvendige trykkraft. Hvis den uunderst\u00f8ttede l\u00e6ngde er l\u00e6ngere, b\u00f8r der anvendes en k\u00e6de med en st\u00f8rre H-dimension (h\u00f8jere pladeprofil), da den har st\u00f8rre sektionsstivhed.

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;\">Hvad er forskellen mellem EP-08BF20 og EP-08BF208?<\/summary>\n<div style=\"padding: 16px 18px; font-size: clamp(13px,1.5vw,15px); color: #334155; line-height: 1.75;\">B\u00e5de EP-08BF20 og EP-08BF208 deler samme stigning (12,700 mm), rullediameter (8,51 mm), indvendig bredde (7,75 mm), stiftdiameter (4,45 mm) og pladeh\u00f8jdedimensioner. Forskellen er den minimale tr\u00e6kstyrke: EP-08BF20 er klassificeret til 18,0 kN\/4046 lbf, og EP-08BF208 er klassificeret til 10,0 kN\/2248 lbf. Dette afspejler en forskel i pladetykkelse eller pladematerialebehandling mellem de to modeller. EP-08BF208 er specificeret til applikationer med lavere belastning eller til aktuatorer, hvor det originale design bruger en lettere pladespecifikation. EP-08BF20 er den h\u00f8jere styrkemulighed til applikationer, der kr\u00e6ver st\u00f8rre tryk- og tr\u00e6kkraftkapacitet.

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;\">Hvad vores kunder siger<\/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.
