This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLightweight\u003c\/strong\u003e: Kilogram for kilogram of working load, Ball Bearing Orbit Blocks are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHighest working load in its class:\u003c\/strong\u003e The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow profile and compact\u003c\/strong\u003e: The two way head in the single lashing block allows for alignment at 0° or 90° orientation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLightweight.\u003c\/li\u003e\n\u003cli\u003eHighest working load in its class.\u003c\/li\u003e\n\u003cli\u003eHigh performance cleating.\u003c\/li\u003e\n\u003cli\u003eSecure, versatile attachment.\u003c\/li\u003e\n\u003cli\u003eUltra low profile thru-sheave becket.\u003c\/li\u003e\n\u003cli\u003eLow friction 2-stage ball bearing system provides consistent performance over the full working load range.\u003c\/li\u003e\n\u003cli\u003eSelf-lubricating Nylatron sheave and full contact bearing for high dynamic loads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSheave: self-lubricating Nylatron.\u003c\/li\u003e\n\u003cli\u003eFrame\/Cheeks: toughened, glass fibre reinforced nylon.\u003c\/li\u003e\n\u003cli\u003eHub: 316 stainless steel.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594331644276,"sku":"RONRF35101D","price":32.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF35101D-2__00801.jpg.1428984928.jpg?v=1761730271","url":"https:\/\/velasailingsupply.com\/products\/ronstan-series-30-orbit-block-single-becket-fixed-head","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
