Series 30 Ball Bearing Block Single Becket Option Lashing
Ball Bearing Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.
Highest Working Load in its Class
The proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.
The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.
Simple, Versatile & Secure Attachment
The single block is easily lashed to an attachment point, and can also accept Dyneema® Links and shackles for a variety of efficient attachment alternatives. The Dyneema® Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema® Link can also be removed and replaced by a shackle, custom lashing or strop.
These blocks are far more compatible with Dyneema®/Spectra® lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles.
Low Profile & Compact
The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation.
The flexible Dyneema® Link used in multi-sheave blocks provides 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height.
Features:
Lightweight
Highest working load in its class
Secure, versatile and secure attachement
Low profile and compact
Ultra low profile thru-sheave becket
Self-lubricating Nylatron® sheave and full contact bearing for high dynamic loads
Applications:
Mainsheet systems and spinnaker sheets on dinghies to 5M(16')
Halyard, vang and backstay applications on boats to 5M(16')
Control line applications on larger yachts
