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.\u003c\/p\u003e\u003cp\u003eWeight 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.\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\u003cbr\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 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.\u003c\/p\u003e\u003cp\u003eThe 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\u003cp\u003e\u003cstrong\u003eUser Instructions\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eFor comprehensive details including \u003ca href=\"http:\/\/www.ronstan.com\/marine\/orbitblock-instructions.asp\"\u003euser instructions\u003c\/a\u003e, and for spare part tables, and fastener sizes view in various languages using the following links \u003ca href=\"https:\/\/drive.google.com\/file\/d\/0B5-g_RY2uN1Fdm9Td0JnaWczTEE\/edit\"\u003eBB \u0026amp; RT OrbitBlock™ User Instructions\u003c\/a\u003e  (English),  \u003ca href=\"https:\/\/drive.google.com\/file\/d\/0B5-g_RY2uN1FUzlXMWEzYzZabDQ\/edit\"\u003eBB \u0026amp; RT OrbitBlock™ User Instructions\u003c\/a\u003e (French), \u003ca href=\"https:\/\/drive.google.com\/file\/d\/0B5-g_RY2uN1FSmFMellHMWN1VUk\/edit\"\u003eBB \u0026amp; RT OrbitBlock™ User Instructions (German)\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong minmax_bound=\"true\"\u003eDyneema Specialties\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTo gain peak performance, we engineered out the heavy steel load straps, head post, shackle, full-length fasteners, and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.\u003c\/p\u003e\u003cp\u003eThe Dyneema Link is produced from FSE Robline SK75 fibre, 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\u003eThe flexible Dyneema Link provides controlled rotation and 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height.\u003c\/p\u003e\u003cp\u003eIt is easily fitted and is retained securely by a moulded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins.\u003c\/p\u003e\u003cp\u003eThe system is compatible with Dyneema Spectra strops, webbing and carbon connection points - much more so than steel loop tops or shackles.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/www.ronstan.com.au\/assets\/images\/IDP\/IDP345-A.jpg\" style=\"border-width: 0px; border-style: solid; height: 130px; width: 130px;\"\u003e\u003cimg src=\"https:\/\/www.ronstan.com.au\/assets\/images\/IDP\/IDP345-B.jpg\" style=\"border-width: 0px; border-style: solid; height: 130px; width: 130px;\"\u003e\u003cimg src=\"https:\/\/www.ronstan.com.au\/assets\/images\/IDP\/IDP345-C.jpg\" style=\"border-width: 0px; border-style: solid; height: 130px; width: 130px;\"\u003e\u003cimg src=\"https:\/\/www.ronstan.com.au\/assets\/images\/IDP\/IDP345-D.jpg\" style=\"border-width: 0px; border-style: solid; height: 130px; width: 130px;\"\u003e\u003c\/p\u003e\u003ch3\u003e\n\u003cbr\u003e\u003cbr\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMainsheet systems on spinnaker sheet 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\u003ch3\u003e\n\u003cbr\u003e\u003cbr\u003eMaterials\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBall Bearings - High compression stregnth carbon black 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\u003cli\u003eSheave - Carbon fibre reinforced, PTFE impregnated Nylon\u003c\/li\u003e\n\u003cli\u003eRope\/Link - UV stabilised, multi-strand impregnated SK75 Dyneema®\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\n\u003cbr\u003e\u003cbr\u003eProduct Specifications\u003c\/h3\u003e\u003ctable border=\"1\" cellpadding=\"0\" cellspacing=\"0\" style=\"width:230px;\" width=\"100%\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth id=\"eight\"\u003eSheave Ø\u003c\/th\u003e\n\u003ctd id=\"eight\"\u003e40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax.
