The sheave runs on a central stainless steel bush. Ideal for high static loads which are typical in yacht halyard systems. Plain-bearing sheaves are recommended for any system which is subject to winching.\u003c\/p\u003e \u003cp\u003eFor fast running and lower loaded lines take a look at the DB range.\u003c\/p\u003e \u003cp\u003eWe have rated the PB deck organiser range based on a 30-degree turning angle around the sheave. A 30-degree turn on a sheave will have a load factor of 50% of the line load.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eThree plain bearing sheaves.\u003c\/li\u003e \u003cli\u003eLightweight and easy to install.\u003c\/li\u003e \u003cli\u003eStackable.\u003c\/li\u003e \u003cli\u003eSuitable for boats up to 30ft.\u003c\/li\u003e \u003cli\u003eStylish and sleek design.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eExamples Of Use:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eGuiding halyards along a coach roof back to clutches, cleats and winches.\u003c\/li\u003e \u003cli\u003eDiverting control lines around a corner under or over deck.\u003c\/li\u003e \u003cli\u003eUnderdeck take-up systems.\u003c\/li\u003e \u003cli\u003eRedirecting a halyard, sheet or control line to have the correct lead angle into a winch or cleat.\u003c\/li\u003e \u003c\/ul\u003e \u003cdiv class=\"container\"\u003e \u003cdiv class=\"cabDes\"\u003eTechnical Description\u003c\/div\u003e \u003cdiv class=\"col-4 menu units\"\u003eFeatures\u003c\/div\u003e \u003cdiv class=\"col-4 menu units\"\u003eMetric\u003c\/div\u003e \u003cdiv class=\"col-4 menu units\"\u003eAmerican\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eSheave Diameter\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e1.97 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e50 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eLength\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e5.02 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e127.63 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eLine Diameter\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e0.31 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e8 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eShackle Pin\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e0.16 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e4 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eBreaking Load\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e1543.24 lb\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e700 kg\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eMWL\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e440.92 lb\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e200 kg\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eWeight\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e0.18 lb\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e80 g\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eBearing Detail\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e-\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003eDelrin\u003c\/div\u003e \u003c\/div\u003e","brand":"Allen Brothers","offers":[{"title":"Default Title","offer_id":53606411764084,"sku":"ALNA2150FIDDLE","price":112.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/A2160-FIDDLE__54957.jpg.1428984928.jpg?v=1761823940"}],"url":"https:\/\/velasailingsupply.com\/collections\/allen-50mm-pro-ratchet-blocks.oembed","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
