Ronstan Series 60 Core Block, Fiddle, Cleat

De Ronstan Core blokken zijn voorzien van het unieke "dual stage bearing system" wat betekent dat het blok bij extreem hoge belastingen overschakelt van de kogellagering naar een hoog gepolijst glijlager. Hierdoor worden de ballen ontlast waardoor de werkbelasting van dit blok extreem hoog is en het blok minimale weerstand heeft bij zowel lage als hoge belastingen.

De blokken zijn gemaakt uit aluminium waardoor ze zeer solide zijn. De RVS harp kan swivelen of kan worden geblokkeerd. De blokken zijn gemaakt van hoogwaardig aluminium, rvs en bronzen onderdelen. De as van het blok kan worden gebruikt als hondsvot en de hoek van de arm met klem is instelbaar.

PRODUCT INFORMATION
Core Blocks® are a true all round solution. 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.

APPLICATIONS
• Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 11m (36ft).
• Various control line applications on larger yachts.
• Alloy sheave models are available for use with wire.
