  • Sale -15% Ronstan Series 55 Ball Bearing Orbit Block - Single - Becket - Swivel Head [RF55110]

    Ronstan Series 55 Ball Bearing Orbit Block - Single - Becket - Swivel Head [RF55110]

    Series 55 Ball Bearing Orbit Block™ - Single - Becket - Swivel HeadLightweightKilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world's lightest. 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 ClassThe 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® 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.Features: Ultra Lightweight Low friction 2-stage Orbital ball bearing system Highest working load in its class Low profile and compact High performance cleating Swivel shackle head for unlimited block rotation Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points Ultra low profile integrated becket Applications: Mainsheet systems on dinghies, sportsboats and small keelboats to 9M(30') Spinnaker sheets on dinghies, sportsboats and small keel boats to 9M(30') Halyard, Vang and Backstay application on boats to 8M(26') Control line applications on larger yachts Ideal use for mainsheet systems and spinnaker sheets on dinghies, sportsboats and small keel boats to 9M(30') Also ideal with halyard, vang and backstay applications on boats to 8M(26') Spinnaker sheets on sportsboats and small keel boats (lateral lead blocks) Control line applications on larger yachts Materials: Ball bearings - High compression strength carbon black Acetal Stage 2 bearing - Carbon fiber reinforced, PTFE impregnated Nylon Frame/Cheeks - Toughened, glass fiber reinforced Nylon Rope Link: UV stabilized, multi-strand impregmented SK75 Dyneema® Sheave: Carbon fiber reinforced, PTFE impregnated Nylon Head fitting: Grade 316 stainless steel.

    Barton Tufnol Snatch Block f/Wire Fibreoptic Cables [T92100]

    Tufnol Snatch Block for Wire & Fibreoptic CablesThe Barton wire snatch block has been developed specifically as a low maintenance static free block. 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. The cheeks are made from marine grade 316 stainless steel as is the pin and retaining nuts. This block is ideal for commercial applications in the toughest of environments.Specifications: Safe Working Load: 350kg (770lbs) Break Load: 1500kg (3300lbs) Max Rope/Wire size: 10mm (3/8”) Weight: 78grms (2.8oz) Length: 190nn (7 ½”) Width: 115mm (4 ½”) Thickness (Maximum): 53mm (2 1/16”) Fibreoptic & Wire BendingFibreoptic cables and wire ropes require a minimum bend radius to stop failures. This block is suitable for both fibreoptics and wires up to 10mm in diameter. The large sheave means that the bend radius of the wire is not compromised and provides an additional engineered safety factor to prologue the life of wire if continual movement around the same section of wire is required.
