The Tufnol sheave means that static cannot build up in the block and cause electrical discharge. Tufnol is a bearing-grade material so it gives a low-friction surface for the wire to run on and minimizes the number of moving components, giving it reliability and durability.\u0026amp;nbsp; The cheeks are made from marine grade 316 stainless steel as is the pin and retaining nuts.

This block is suitable for both fibreoptics and wires up to 10mm in diameter.

A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Universal Bearing Dynamic and high static load performance The Ronstan Universal Bearing incorporates our proven 2-stage bearing system Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction. Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance. Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn't perfect. Particularly important for cheek blocks. Alloy Cheek Plates Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimisation and the cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimising rope wear. Universal head The head assembly incorporates a brass bearing washer to provide smooth 360\u0026amp;#153; rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0\u0026amp;#153; or 90\u0026amp;#153;. Shackles are high quality forged grade 316 stainless steel. Features: Class leading performance and sleek, contemporary styling Excellent dynamic and high static load performance Less than half the friction of the nearest competitor Universal head with full 3-axis articulation Head posts can be locked at 0 or 90 degrees, by using a 2.5mm Hex\/Allen Key Central hub hole can be used as a becket take-off or tie-up point Applications: Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 14M (46') Various control line applications on larger yachts Materials: Sheave: U.V. stabilized Acetal Cheek body: Aluminium Alloy Ball Bearings: High compression strength carbon black Acetal Shackle, head post \u0026amp; hub: Grade 316 stainless steel Specifications: Sheave \u0026amp;#216;: 75mm(3\") Max.

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. Highest Working Load In Its Class 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 fiber-reinforced load frame. The design was computer modelled to be stress optimised. The Dyneema\u0026amp;reg; 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.

This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers. Awesome Ratchet Block Holding Power Quite simply, Ronstan Ratchet Orbit Blocks\u0026amp;#153; have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor. The unique sheave design has 8 gripping faces which directly resist loaded line movement. Traditional designs have 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. Simple and Secure Attachment The Dyneema\u0026amp;reg; Link 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\u0026amp;reg;\/Spectra\u0026amp;reg; strops, webbing and carbon connection points - much more so than steel loop tops or shackles. Smooth Easing of Sheets With auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. Low Profile Stand-Up Kit Allows 0\u0026amp;#153; or 90\u0026amp;#153; Alignment Stand-up kits feature a clatter-free rubber boot. You can attach the Dyneema\u0026amp;reg; link so that the block is aligned with the stand-up base or across it. It's a neat low-profile solution which allows full articulation.

The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designs 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 minimize rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load Materials: Sheave: Anodized Aluminium Ball Bearings: High compression strength carbon black Acetal Frame\/Cheeks: Toughened, glass fiber reinforced Nylon Rope Link: UV stabilized, multi-strand impregnated SK75 Dyneema\u0026amp;reg;\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"dna-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eRonstan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part number\u003c\/th\u003e\n\u003ctd\u003eRF56510\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart type\u003c\/th\u003e\n\u003ctd\u003eBlocks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUPC \/ GTIN\u003c\/th\u003e\n\u003ctd\u003e9316800480241\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e0.27 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCategory\u003c\/th\u003e\n\u003ctd\u003eTools \u0026amp; Garage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eNew — genuine brand-name product\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eManufacturer warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eQuestions\u003c\/h3\u003e\n\u003cdiv class=\"dna-faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eHow fast does it ship?\u003c\/summary\u003e\u003cp\u003eOrders ship from the closest US warehouse, normally within 1–3 business days, with tracking by e-mail.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eIs this a genuine Ronstan product?\u003c\/summary\u003e\u003cp\u003eYes — new and genuine Ronstan, with the manufacturer warranty.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I return it?\u003c\/summary\u003e\u003cp\u003eYes.
