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. \u003cbr\u003e\u003cbr\u003e The Orbit sheave has captive Acetal 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.Head posts of swivel blocks can be locked at 0 or 90 degrees.\u003cbr\u003e\u003cbr\u003e\u003cspan class=\"subtitles_red\"\u003eApplications\u003c\/span\u003e\u003cli\u003ePrimary mainsheet, halyard and spinnaker systems on boats to 14 m (46 ft)\u003c\/li\u003e\n\u003cli\u003eSecondary mainsheet, vang blocks on boats to 15 m (50 ft)\u003c\/li\u003e\n\u003cli\u003eStandard and running backstay systems on boats to 12 m (40 ft)\u003c\/li\u003e\n\u003cli\u003eGeneral control line and lead block applications on larger yachts\u003c\/li\u003e\n\u003cspan class=\"subtitles_red\"\u003eMaterials\u003c\/span\u003e\u003cbr\u003e\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\u003cli\u003eForged grade 17-4PH stainless steel shackles\u003c\/li\u003e\n\u003cli\u003eGrade 316 stainless steel head post\u003c\/li\u003e\n\u003c\/div\u003e\n\u003c!-- FIN SCRIP PANLS--\u003e\n\u003c\/div\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594583925108,"sku":"RONRF79110","price":572.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF79110-2__66916.jpg.1428984928.jpg?v=1761730699","url":"https:\/\/velasailingsupply.com\/products\/ronstan-series-75-orbit-block-single-becket","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
