composite fibre blocks

COMPOSITE FIBRE SERIES

The whole “composite fibre” range uses sheaves on composite fibre bearings and double self-captive Delrin ball thrust bearings.

The sheaves are easy to dismantle for cleaning and need no lubrication.
The sides are made of 3571 TA16 light alloy and are thickly anodized to ensure absolute wear-and corrosion proofing, with all the edges smoothed off for better handling.

The nuts and bolts have been replaced with recessed screws and pins, considerably reducing weight and eliminating any projecting parts.
The steel coupling revolves on a fibre washer and can easily be locked in one of two main positions.

HIGH-STRENGTH RESIN SHEAVES


All blocks in sizes 75, 90 and 120 mm have high-strength resin sheaves to reduce weight while retaining their capacity for very high work loads. Sizes 150, 180 and 225 mm still use thickly anodized aluminium sheaves.
The main bearing is made of high-strength composite fibre impregnated with self-lubricating substances. A double lateral Delrin ball bearing makes the sheaves slide perfectly smoothly.

Sheaves are supplied with the s.steel central hub, they are available separately.

  

WEB SERIES BLOCKS


This range is designed to achieve minimum weight while retaining strength and durability. The 17-4-PH high-strength stainless steel coupling means the block can be tied with webbing or thin Spectra or Kevlar lines giving the lightest connection possible.
New “strengthened” (/Z) models suitable to also higher loads.
 

S.STEEL BLOCKS


Blocks and deck blocks of this series can be supplied with s. steel cheekplates and hub (AISI 316).
