    Product Description


     

    Features:
    Class leading performance and sleek, contemporary styling
    Excellent dynamic and high static load performance
    Less than half the friction of the nearest competitor
    Removable becket pin for fitting of pre-spliced lines
    ** Line load through cleat not to exceed 175kg (385lb)

    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 12m (40ft).
    Various control line applications on larger yachts.
    Alloy sheave models are available for use with wire.

    Materials:
    Sheave: U.V. stabilised Acetal or anodised aluminium (AW models)
    Cheek plates: Aluminium alloy
    Ball Bearings: High compression strength carbon black Acetal

    Product Description

    Patented system uses low profile cars running on twin races of Acetal ball bearings. Cars use the existing luff groove of the mast (no track or installation work required). Ball bearings are captive for easy loading and unloading of cars from mast. They can be easily switched between fully battened and "soft luff" mainsails. Minimum distance from mast to mainsail luff enhances mainsail efficiency.

    • Captive.
    • Low profile.
    • Lightweight alloy car bodies.
    • Alloy car bodies.
    • Carbon black Acetal ball bearings.
