The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub.\u003c\/p\u003e\u003cp\u003eWeight and bulk are further reduced in the different block configurations. The ball bearing single and becket block have a through-sheave becket arrangement. The result? The lowest weight is possible.\u003c\/p\u003e\u003cp\u003eMulti-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\u003cp\u003e\u003cstrong\u003eHighest working load in its class\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes 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.\u003cbr\u003e\u003cbr\u003eThe floating sheave and bearing system are supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized. The Dyneema® Link is produced from FSE Robline SK75 fiber, which is 10 times stronger and lighter than steel and provides the final connection from the block to the load point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUltra Lightweight\u003c\/li\u003e\n\u003cli\u003eLow friction 2-stage Orbital ball bearing system\u003c\/li\u003e\n\u003cli\u003eHighest working load in its class\u003c\/li\u003e\n\u003cli\u003eLow profile and compact\u003c\/li\u003e\n\u003cli\u003eHigh performance cleating\u003c\/li\u003e\n\u003cli\u003eSwivel shackle head for unlimited block rotation\u003c\/li\u003e\n\u003cli\u003eStainless steel shackle head and compatibility with sharp fixing points\u003c\/li\u003e\n\u003cli\u003eUltra low profile integrated beckets\u003c\/li\u003e\n\u003c\/ul\u003e \u003c!--- cis2:m2hslppl ---\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":44445948936493,"sku":"U-9316800442645","price":166.16,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/1469\/6749\/products\/88900XL__31200.jpg?v=1675828096","url":"https:\/\/ibs-rvmarines.ca\/products\/ronstan-series-55-bb-orbit-block-double-becket-swivel","provider":"IBS RVMarines","version":"1.0","type":"link"}
