The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of the inactive return race and hub. 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. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHighest working load in its class\u003c\/strong\u003e\u003cbr\u003e. The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. 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 floating sheave and bearing system is supported by a fibre-reinforced load frame. The design was computer modelled to be stress optimised.\u003c\/p\u003e\n\u003cp\u003eRecommended fasteners - 3 x 4mm (5\/32\") countersunk head screws.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-size-guide\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"product-size-compare\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"tech-info spec-empty\"\u003e\n\u003ch2\u003eTECHNICAL INFORMATION\u003c\/h2\u003e\n\u003cdiv class=\"app-material\"\u003e\n\u003ch3\u003eAPPLICATIONS\u003c\/h3\u003e\n\u003cul class=\"bullet-list\"\u003e\n\u003cli\u003eMainsheet systems and spinnaker sheets on dinghies to 5m (16ft)\u003c\/li\u003e\n\u003cli\u003eSpinnaker sheets on dinghies, sportsboats and small keel boats to 5m (16ft)\u003c\/li\u003e\n\u003cli\u003eHalyard, vang and backstay applications on boats to 8m (26ft)\u003c\/li\u003e\n\u003cli\u003eControl line applications on larger yachts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eMATERIALS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSheave: Carbon fibre reinforced, PTFE impregnated nylon.\u003c\/li\u003e\n\u003cli\u003eBall bearings: High compression strength acetal.\u003c\/li\u003e\n\u003cli\u003eStage 2 bearing: Glass fibre reinforced, MoS2 impregnated nylon.\u003c\/li\u003e\n\u003cli\u003eFrame\/cheeks: Toughened, glass fibre reinforced nylon.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row collapse\"\u003e\n\u003cdiv class=\"large-9 columns\"\u003e\n\u003cdiv align=\"left\" minmax_bound=\"true\"\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":52812122718437,"sku":"RF45151","price":59.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0752\/6495\/0501\/files\/RF45151.jpg?v=1789271961","url":"https:\/\/www.stevestonmarine.com\/products\/block-cheek-40mm-series-40-bb-orbit-block","provider":"Steveston Marine and Hardware","version":"1.0","type":"link"}
