Halyard blocks have a removable pin for attachment to deck padeyes or mast collar.\u003c\/p\u003e\n\u003cp\u003eOrbit Blocks are a no-compromise product range developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners.\u003c\/p\u003e\n\u003cp\u003eThe Orbit sheave has captive acetal or Torlon ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon needles – achieving a substantially higher strength-to-weight ratio.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe highest strength-to-weight ratio.\u003c\/li\u003e\n\u003cli\u003eMinimal friction loss, especially when working at high loads.\u003c\/li\u003e\n\u003cli\u003eTotally reliable and trouble free performance.\u003c\/li\u003e\n\u003cli\u003eSimplicity of design and construction to facilitate maintenance and servicing.\u003c\/li\u003e\n\u003cli\u003eElegant, functional styling and finish.Removable pin.\u003c\/li\u003e\n\u003cli\u003eBushed to 14mm (9\/16\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFully machined Alloy cheek plates.\u003c\/li\u003e\n\u003cli\u003eAlloy sheaves with captive ball races.\u003c\/li\u003e\n\u003cli\u003eTorlon needle rollers.\u003c\/li\u003e\n\u003cli\u003eCarbon black Acetal ball bearings.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594582974836,"sku":"RONRF79108","price":427.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF79108-2__14504.jpg.1428984928.jpg?v=1761730697","url":"https:\/\/velasailingsupply.com\/products\/ronstan-series-75-orbit-block-single-halyard","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
