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\u003c\/p\u003e\n\u003cp\u003eKilogram for kilogram of working load BB 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. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHighest working load in its class\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe proven Ronstan 2-stage bearing system (Series 30 and larger) 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\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBase suits curved mounting base.\u003c\/li\u003e\n\u003cli\u003eLightweight.\u003c\/li\u003e\n\u003cli\u003eHighest working load in its class.\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\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSheave: High compression strength carbon black Acetal.\u003c\/li\u003e\n\u003cli\u003eBall Bearings: High compression strength Acetal.\u003c\/li\u003e\n\u003cli\u003eFrame\/Cheeks: Toughened, glass fibre reinforced Nylon.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594332856692,"sku":"RONRF35151","price":19.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF35151-2__72894.jpg.1428984928.jpg?v=1761730274","url":"https:\/\/velasailingsupply.com\/products\/ronstan-series-30-bb-orbit-block-cheek","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
