{"product_id":"harken-12-integral-backstay-cylinder-40mm-bore-385mm-stroke","title":"Harken -12 Integral Backstay Cylinder - 40mm Bore, 385mm Stroke","description":"\u003cp\u003eHarken’s integral hydraulic backstay adjuster provides the power to optimize sail shape quickly. The cylinder features a built-in, double-acting pump that delivers oil when the handle is both pushed and pulled. This moves oil through the system twice as fast as single-acting pumps on other integrals.\u003cbr\u003e\r\nAssemblies include a hardcoat-anodized aluminum cylinder and pump, valve, and stainless pump handle with three attachment options: pin installs handle permanently; O-ring secures handle in socket, but is not permanent; nonlocking handle installs without O-ring and roll pin. All pins and plugs are stainless steel. Cylinders include a clevis on both ends. Standard eye-jaw toggles fit all Harken® cylinders.\u003cbr\u003e\r\nThe pressure release knob turns clockwise to close and pump, counterclockwise to release. When closing the pump, the knob cannot be over-tightened by hand, preventing damage to the valve. Release speed depends on how far open the knob is turned. Pressure relief is factory set to prevent crew from over-tensioning the backstay.\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cstrong\u003eFootnote:\u003c\/strong\u003e For pin center length open add stroke length to pin center length closed., Max relief setting is 5, 000 psi \/ 345 bar., Rod ends (forks) included in weights.\u003c\/p\u003e\r\n\r\n\u003ctable border=\"1\" cellpadding=\"1\" cellspacing=\"1\" style=\"width:500px;\"\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003e- Size\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e-12\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003ePull force @ 1000 psi\/69 bar (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e952 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003eMaximum wire Ø (mm)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e8  mm\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003ePull force @ 2000 psi\/138 bar (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e1904 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003eStroke (mm)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e385 mm\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003ePull force @ 3000 psi\/207 bar (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e2855 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003ePin center length (closed) (mm)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e832 mm\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003ePull force @ 4000 psi\/276 bar (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e3807 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003eWeight (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e4.92 kg\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003ePull force @ 5000 psi\/345 bar (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e4759 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003eGap\/pin Ø (mm)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e15.9 mm\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003eBreaking load (kg)\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e9518 kg\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ctable border=\"0\" cellpadding=\"1\" cellspacing=\"1\"\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003eDownload \/ View Drawing \u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\u003ca href=\"https:\/\/www.harken.co.uk\/UploadedFiles\/Products\/79f7677f-e674-4e5a-b8bf-5a11429fd952.pdf\" target=\"_blank\"\u003e\u003cimg alt=\"\" src=\"\/images\/source\/Icons_\/PDF_Button.gif\" style=\"width: 100px; height: 96px;\"\u003e\u003c\/a\u003e\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n","brand":"RIGGINGONLY","offers":[{"title":"Default Title","offer_id":40487922729151,"sku":"HCI040160385BCC.NG","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/7987\/0143\/products\/Integral_Backstay_Cylinder_69f111f4-30ae-4b5d-b1e7-6f1a89ece16e.jpg?v=1629486598","url":"https:\/\/justrigging.com\/products\/harken-12-integral-backstay-cylinder-40mm-bore-385mm-stroke","provider":"JUSTRIGGING.COM","version":"1.0","type":"link"}
