Poulie réa 55mm - Orbit - violon taquet coinceur - attache Dyneema
Réf. RF55521
Description
Fiddle block with adjustable cleat and Dyneema® Link Head.
FEATURES
Ultra Lightweight
Low friction 2-stage Orbital ball bearing system
Highest working load in its class
Low profile and compact
High performance cleating
Easily fitted and securely retained Dyneema® Link head
Composite C-Cleat™ and fairlead
Lightweight
Kilogram 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 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 fibre-reinforced load frame. The design was computer modelled to be stress optimised. 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.
High performance cleating
Both Ronstan BB and RT Orbit Blocks™ feature strong, lightweight fibre-reinforced cleat arms. They have a wide range of adjustment and calibration marks, per
