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. Lightweight Kilogram 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. The Dyneema Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. Simple, versatile and secure attachment The single block is easily lashed to an attachment point, and can also accept Dyneema Links and shackles for a variety of efficient attachment alternatives. The Dyneema Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema Link can also be removed and replaced by a shackle, custom lashing or strop. These blocks are far more compatible with Dyneema\/Spectra lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles. Low profile and compact The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation. The flexible Dyneema Link used in multi-sheave blocks provides 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. High performance cleating Ronstan BB Orbit Blocks feature strong, lightweight fibre-reinforced cleat arms optimised at the required cleating angle. Race-proven, carbon-fibre reinforced Ronstan C-Cleats give secure rope holding with low entry and exit efforts, and are fitted with fairleads for fast action from any angle. *RF35100 \u0026amp; RF35100D have stainless steel head posts \u0026amp; shackles.\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\u003eSecure, versatile attachment.\u003c\/li\u003e\n\u003cli\u003eLow profile and compact.\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\u003eSP versions feature a Nylatron sheave suitable for both rope and wire\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\u003cli\u003eLink: UV stabilised, multi-strand impregnated SK75 Dyneema\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594330399092,"sku":"RONRF35100","price":24.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF35100-2__34573.jpg.1428984928.jpg?v=1761730267"},{"product_id":"ronstan-series-30-bb-orbit-block-single-slotted-head-post","title":"Ronstan Series 30 BB Orbit Block, Single Slotted Head Post","description":"\u003cp\u003e\u003cstrong\u003eRonstan Series 30 BB Orbit Block, Single Slotted Head Post\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBall Bearing Orbit Blocks boast the highest strength-to-weight ratio available.

The 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 The 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.

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\u003c\/p\u003e\n\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. The floating sheave and bearing system is supported by a fibre-reinforced load frame.

Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents The Dyneema Link is produced from Robline SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. The 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 It 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 The system is compatible with Dyneema Spectra strops, webbing and carbon connection points - much more so than steel loop tops or shackles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh performance cleating\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth Ronstan BB and RT Orbit Blocks feature strong, lightweight fibre-reinforced cleat arms.

The sophisticated CNC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. Its holding power is up to 20:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 20:1 holding power\u003c\/li\u003e\n\u003cli\u003eSmooth easing of sheets\u003c\/li\u003e\n\u003cli\u003eUltra-low profile integrated hollow hub becket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePin Ø (in): 3\/16\u003c\/li\u003e\n\u003cli\u003eSheave diameter (in): 2 5\/32 + 1 3\/8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRatchet Sheave: Anodised Aluminium\u003c\/li\u003e\n\u003cli\u003eBall Bearings: High compression strength carbon black Acetal\u003c\/li\u003e\n\u003cli\u003eFrame \/ Cheeks \/ Cleat Arms: Toughened, glass fibre reinforced Nylon\u003c\/li\u003e\n\u003cli\u003eSwivel shackle head fitting: Grade 316 stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594476020084,"sku":"RONRF56510","price":99.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF56510-2__27571.jpg.1428984928.jpg?v=1761730519"},{"product_id":"ronstan-series-55-orbit-block-ratchet-with-fiddle-becket-and-cam-cleat","title":"Ronstan Series 55 Orbit Block Ratchet with Fiddle Becket and Cam Cleat","description":"\u003cp\u003e\u003cstrong\u003eRonstan Series 55 Orbit Block Ratchet with Fiddle Becket and Cam Cleat\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAutomatic ratchet block\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNow you can enjoy the flexibility of setting up your ratchet blocks to suit yourself.
